Visibility on config_setting isn't historically enforced. This is purely for legacy reasons. There's no philosophical reason to distinguish them.

This flag starts the process of removing the distinction.

Values:

  • --incompatible_enforce_config_setting_visibility=off: every config_setting is visible to every target, regardless of visibility settings
  • --incompatible_enforce_config_setting_visibility=on: config_setting follows the policy set by --incompatible_config_setting_private_default_visibility (incompatible_config_setting_private_default_visibility #12933).

Incompatibility error:

ERROR: myapp/BUILD:4:1: in config_setting rule //myapp:my_config: target 'myapp:my_config' is not visible from target '//some:other_target. Check the visibility declaration of the former target if you think the dependency is legitimate

Migration:

Treat all config_settings as if they follow standard visibility logic at https://docs.bazel.build/versions/master/visibility.html: have them set visibility explicitly if they'll be used anywhere outside their own package. The ultimate goal of this migration is to fully enforce that expectation.

Release 5.0.0-pre.20210510.2 (2021-05-31)
e7d3480 
Baseline: 8a42645

Cherry picks:

   + e3c78c4:
     Ensure that test status artifacts are reported as top-level
     artifacts.
   + 1f52e9a:
     Support rolling releases in Bazel release scripts.

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    #7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See #11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    #12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.

497a848 
Baseline: 37a429a

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

     Add incompatible flag to guard top-level aspects dependencies

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    #7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
  - Native libraries in data attribute are not collected. See
    #13550 for details
  - Enforce the `--profile` path to be absolute.
  - Enforce the --memory_profile path to be absolute.
  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
  - --apple_sdk has been deleted.  It is a no-op.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See #11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    #12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
  - Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
  - Remove obsolete --incompatible_prohibit_aapt1
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
  - --experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
  - Forward coverage-instrumented files from non-tool dependencies by
    default.
  - The used_heap_size_post_build field in BEP is populated when the
    --memory_profile flag is set
  - --run_validations defaults to true.
  - Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
  - Remove flag
    --experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
  - When using MemoryProfiler with multiple GCs via the
    --memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
  - --bep_publish_used_heap_size_post_build is deprecated. Use
    --memory_profile=/dev/null instead.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Release 5.0.0-pre.20210826.1 (2021-09-03)
d13f58b 
Baseline: f53c389

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    #7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
  - Native libraries in data attribute are not collected. See
    #13550 for details
  - Enforce the `--profile` path to be absolute.
  - Enforce the --memory_profile path to be absolute.
  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
  - --apple_sdk has been deleted.  It is a no-op.
  - --bep_publish_used_heap_size_post_build is now a no-op and will
    be deleted in a future release. Use --memory_profile=/dev/null
    instead.
  - Flipped --incompatible_disallow_resource_jars (see
    #13221).

New features:

  - Args.add_all and Args.add_joined can now accept closures in
    map_each if explicitly enabled via allow_closure.
  - Add `--bes_header` flag to pass extra headers to the BES server.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See #11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    #12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
  - Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
  - Remove obsolete --incompatible_prohibit_aapt1
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
  - --experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
  - Forward coverage-instrumented files from non-tool dependencies by
    default.
  - The used_heap_size_post_build field in BEP is populated when the
    --memory_profile flag is set
  - --run_validations defaults to true.
  - Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
  - Remove flag
    --experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
  - When using MemoryProfiler with multiple GCs via the
    --memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
  - --bep_publish_used_heap_size_post_build is deprecated. Use

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

26cb401 
Baseline: 37a429a

Cherry picks:

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.
     getRootRelativePath doesn't return a valid runfiles path for
     external source files anymore after the recent external source
     root change. Also, it won't work for external labels either once
     the --nolegacy_external_runfiles becomes default. This fixes
     issue #12545.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

10218e7 
Baseline: 37a429a

Cherry picks:

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.
     getRootRelativePath doesn't return a valid runfiles path for
     external source files anymore after the recent external source
     root change. Also, it won't work for external labels either once
     the --nolegacy_external_runfiles becomes default. This fixes
     issue #12545.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Cherry picks:

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.
     getRootRelativePath doesn't return a valid runfiles path for
     external source files anymore after the recent external source
     root change. Also, it won't work for external labels either once
     the --nolegacy_external_runfiles becomes default. This fixes
     issue #12545.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Release 6.0.0-pre.20211117.1 (2021-12-07)
139081f 
Baseline: e5b3536

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    #7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
  - Native libraries in data attribute are not collected. See
    #13550 for details
  - Enforce the `--profile` path to be absolute.
  - Enforce the --memory_profile path to be absolute.
  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
  - --apple_sdk has been deleted.  It is a no-op.
  - --bep_publish_used_heap_size_post_build is now a no-op and will
    be deleted in a future release. Use --memory_profile=/dev/null
    instead.
  - Flipped --incompatible_disallow_resource_jars (see
    #13221).
  - Remove --bep_publish_used_heap_size_post_build
  - JSON trace profile: rename counter names.
  - Removed --action_graph from the dump command.
  - Remove `--{experimental_,}json_trace_compression` option.
  - Remove `--experimental_profile_cpu_usage`.
  - flipped --incompatible_java_common_parameters (see #12373)

New features:

  - Args.add_all and Args.add_joined can now accept closures in
    map_each if explicitly enabled via allow_closure.
  - Add `--bes_header` flag to pass extra headers to the BES server.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See #11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    #12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
  - Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
  - Remove obsolete --incompatible_prohibit_aapt1
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
  - --experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
  - Forward coverage-instrumented files from non-tool dependencies by
    default.
  - The used_heap_size_post_build field in BEP is populated when the
    --memory_profile flag is set
  - --run_validations defaults to true.
  - Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
  - Remove flag
    --experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
  - When using MemoryProfiler with multiple GCs via the
    --memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
  - --bep_publish_used_heap_size_post_build is deprecated. Use
    --memory_profile=/dev/null instead.
  - Disable --all_incompatible_changes flag.
  - The --all_incompatible_changes flag is now a no-op
  - The `--toolchain_resolution_debug` flag now accepts regexes
    matching targets, as well as toolchain types, when choosing what
    debug messages to print.
  - Adds --experimental_existing_rules_immutable_view flag to make the
    native.existing_rule and native.existing_rules functions more
    efficient by
    returning immutable, lightweight dict-like view objects instead
    of mutable
    dicts.
  - Add support to length-delimited protos as undeclared output
    annotations []
  - The deprecated "relative_to_caller_repository" parameter has been
    removed from the Label constructor.
  - The toolchain transition is now enabled for all toolchains.
  - incompatible_disable_depset_items is flipped
  - The --experimental_existing_rules_immutable_view flag has been
    renamed to  --incompatible_existing_rules_immutable_view
  - Bazel no longer supports Java 8. From this version on, the
    minimum required JDK is OpenJDK 11.
  - Deprecate --incompatible_applicable_licenses flag, in preparation
    for removal in Bazel 6.x.
  - Treat py_*.srcs_version="PY2" the same as "PY2ONLY".
  - The Build Event Protocol now contains file digests and sizes
    along with the file name and URI.
  - Refactor system suspend event handling.

Baseline: 37a429a

Cherry picks:

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.
     getRootRelativePath doesn't return a valid runfiles path for

     the --nolegacy_external_runfiles becomes default. This fixes
     issue bazelbuild#12545.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

9ab9e5d 
Baseline: 37a429a

Cherry picks:

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.
     getRootRelativePath doesn't return a valid runfiles path for

     root change. Also, it won't work for external labels either once
     the --nolegacy_external_runfiles becomes default. This fixes
     issue bazelbuild#12545.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Release 6.0.0-pre.20211117.1 (2021-12-07)
a7a4fb4 
Baseline: e5b3536

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    bazelbuild#7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (bazelbuild#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
  - Native libraries in data attribute are not collected. See
    bazelbuild#13550 for details
  - Enforce the `--profile` path to be absolute.
  - Enforce the --memory_profile path to be absolute.
  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
  - --apple_sdk has been deleted.  It is a no-op.
  - --bep_publish_used_heap_size_post_build is now a no-op and will
    be deleted in a future release. Use --memory_profile=/dev/null
    instead.
  - Flipped --incompatible_disallow_resource_jars (see
    bazelbuild#13221).
  - Remove --bep_publish_used_heap_size_post_build
  - JSON trace profile: rename counter names.
  - Removed --action_graph from the dump command.
  - Remove `--{experimental_,}json_trace_compression` option.
  - Remove `--experimental_profile_cpu_usage`.
  - flipped --incompatible_java_common_parameters (see bazelbuild#12373)

New features:

  - Args.add_all and Args.add_joined can now accept closures in
    map_each if explicitly enabled via allow_closure.
  - Add `--bes_header` flag to pass extra headers to the BES server.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    bazelbuild#10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    bazelbuild#10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    bazelbuild#10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See bazelbuild#11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
  - Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
  - Remove obsolete --incompatible_prohibit_aapt1
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
  - --experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
  - Forward coverage-instrumented files from non-tool dependencies by
    default.
  - The used_heap_size_post_build field in BEP is populated when the
    --memory_profile flag is set
  - --run_validations defaults to true.
  - Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
  - Remove flag
    --experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
  - When using MemoryProfiler with multiple GCs via the
    --memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
  - --bep_publish_used_heap_size_post_build is deprecated. Use
    --memory_profile=/dev/null instead.
  - Disable --all_incompatible_changes flag.
  - The --all_incompatible_changes flag is now a no-op
  - The `--toolchain_resolution_debug` flag now accepts regexes
    matching targets, as well as toolchain types, when choosing what
    debug messages to print.
  - Adds --experimental_existing_rules_immutable_view flag to make the
    native.existing_rule and native.existing_rules functions more
    efficient by
    returning immutable, lightweight dict-like view objects instead
    of mutable
    dicts.
  - Add support to length-delimited protos as undeclared output
    annotations []
  - The deprecated "relative_to_caller_repository" parameter has been
    removed from the Label constructor.
  - The toolchain transition is now enabled for all toolchains.
  - incompatible_disable_depset_items is flipped
  - The --experimental_existing_rules_immutable_view flag has been
    renamed to  --incompatible_existing_rules_immutable_view
  - Bazel no longer supports Java 8. From this version on, the
    minimum required JDK is OpenJDK 11.
  - Deprecate --incompatible_applicable_licenses flag, in preparation
    for removal in Bazel 6.x.
  - Treat py_*.srcs_version="PY2" the same as "PY2ONLY".
  - The Build Event Protocol now contains file digests and sizes
    along with the file name and URI.
  - Refactor system suspend event handling.

     [4.2.3] Update GrpcRemoteDownloader to only include relevant
     headers. (#16450) (#16459)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes #16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

     (#16253)
   + f6cccae:
     * add change to allow blaze info to skip Starlark build settings
     that start with --no prefix * add unit tests for both info and
     clean commands
   + 59b8b8f:
     Release 5.3.1 (2022-09-19)
   + 77f0233:
     Update GrpcRemoteDownloader to only include relevant headers.
     (#16450)
   + 42ff95a:
     Avoid unnecessary iteration on action inputs.
   + d29034e:
     Update flag `--experimental_remote_download_regex` to accept
     multiple regular expressions. (#16478)

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    #7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
  - Native libraries in data attribute are not collected. See
    #13550 for details
  - Enforce the `--profile` path to be absolute.
  - Enforce the --memory_profile path to be absolute.
  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
  - --apple_sdk has been deleted.  It is a no-op.
  - --bep_publish_used_heap_size_post_build is now a no-op and will
    be deleted in a future release. Use --memory_profile=/dev/null
    instead.
  - Flipped --incompatible_disallow_resource_jars (see
    #13221).
  - Remove --bep_publish_used_heap_size_post_build
  - JSON trace profile: rename counter names.
  - Removed --action_graph from the dump command.
  - Remove `--{experimental_,}json_trace_compression` option.
  - Remove `--experimental_profile_cpu_usage`.
  - flipped --incompatible_java_common_parameters (see #12373)
  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes #16439.

New features:

  - Args.add_all and Args.add_joined can now accept closures in
    map_each if explicitly enabled via allow_closure.
  - Add `--bes_header` flag to pass extra headers to the BES server.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See #11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    #12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
  - Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
  - Remove obsolete --incompatible_prohibit_aapt1
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
  - --experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
  - Forward coverage-instrumented files from non-tool dependencies by
    default.
  - The used_heap_size_post_build field in BEP is populated when the
    --memory_profile flag is set
  - --run_validations defaults to true.
  - Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
  - Remove flag
    --experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
  - When using MemoryProfiler with multiple GCs via the
    --memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
  - --bep_publish_used_heap_size_post_build is deprecated. Use
    --memory_profile=/dev/null instead.
  - Disable --all_incompatible_changes flag.
  - The --all_incompatible_changes flag is now a no-op
  - The `--toolchain_resolution_debug` flag now accepts regexes
    matching targets, as well as toolchain types, when choosing what
    debug messages to print.
  - Adds --experimental_existing_rules_immutable_view flag to make the
    native.existing_rule and native.existing_rules functions more
    efficient by
    returning immutable, lightweight dict-like view objects instead
    of mutable
    dicts.
  - Add support to length-delimited protos as undeclared output
    annotations []
  - The deprecated "relative_to_caller_repository" parameter has been
    removed from the Label constructor.
  - The toolchain transition is now enabled for all toolchains.
  - incompatible_disable_depset_items is flipped
  - The --experimental_existing_rules_immutable_view flag has been
    renamed to  --incompatible_existing_rules_immutable_view
  - Bazel no longer supports Java 8. From this version on, the
    minimum required JDK is OpenJDK 11.
  - alias() can now select() directly on constraint_value()

    Fixes #13047.

    Closes #14310.
  - Fixed an issue where Bazel could erroneously report a test passes
    in coverage mode without actually running the test.
  - Make protocOpts() publicly accessible.
  - Add coverage configuration fragment, used to expose
    output_generator label.
  - Bazel now no longer includes system headers on macOS in coverage
    reports (#14969).

    Closes #14971.
  - Starlark test rules can use the new inherited_environment
    parameter of testing.TestEnvironment to specify environment
    variables
    whose values should be inherited from the shell environment.

    Closes #14849.
  - none
    RELNOTES:none
  - Enable merging permissions during Android manifest merging with
    the --merge_android_manifest_permissions flag.
  - Added new register_{execution_platforms,toolchains} directives to
    the MODULE.bazel file, to replace the
    {execution_platforms,toolchains}_to_register attributes on the
    module() directive.
  - Add support for fetching RPC credentials from credential helper.

    Progress on #15856

    Closes #15947.
  - `cquery`'s new output mode
    [`--output=files`](https://bazel.build/docs/cquery#files-output)
    lists the output files of the targets matching the query. It
    takes the current value of `--output_groups` into account.

    Closes #15552.
  - Fix for desugaring failure on Bazel+Android+Windows build
    scenario.

Incompatible changes:

-   Removing java_common.javac_jar Starlark call.
-   native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
-   flipped incompatible_use_toolchain_resolution_for_java_rules, see
    [#&#8203;7849](https://togithub.com/bazelbuild/bazel/issues/7849)
-   Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
-   Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
-   Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
-   In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
-   //visibility:legacy_public has been removed.
-   Flip and remove incompatible_dont_collect_so_artifacts

[https://github.com/bazelbuild/bazel/issues/13043](https://togithub.com/bazelbuild/bazel/issues/13043)3043).
-   Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
-   The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
-   Native libraries in data attribute are not collected. See

-   Enforce the `--profile` path to be absolute.
-   Enforce the --memory_profile path to be absolute.
-   JavaToolchainInfo.jvm_opt returns Depset instead of a list.
-   \--apple_sdk has been deleted.  It is a no-op.
-   \--bep_publish_used_heap_size_post_build is now a no-op and will
    be deleted in a future release. Use --memory_profile=/dev/null
    instead.
-   Flipped --incompatible_disallow_resource_jars (see

[https://github.com/bazelbuild/bazel/issues/13221](https://togithub.com/bazelbuild/bazel/issues/13221)3221).
-   Remove --bep_publish_used_heap_size_post_build
-   JSON trace profile: rename counter names.
-   Removed --action_graph from the dump command.
-   Remove `--{experimental_,}json_trace_compression` option.
-   Remove `--experimental_profile_cpu_usage`.
- flipped --incompatible_java_common_parameters (see
[#&#8203;12373](https://togithub.com/bazelbuild/bazel/issues/12373))
-   GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

Closes
[#&#8203;16439](https://togithub.com/bazelbuild/bazel/issues/16439).

New features:

-   Args.add_all and Args.add_joined can now accept closures in
    map_each if explicitly enabled via allow_closure.
-   Add `--bes_header` flag to pass extra headers to the BES server.

Important changes:

-   Flag --incompatible_objc_compile_info_migration is removed.  See
    [#&#8203;10854](https://togithub.com/bazelbuild/bazel/issues/10854).
-   Flag --incompatible_objc_compile_info_migration is removed.  See

-   none
    PAIR=cmita
-   The --incompatible_load_python_rules_from_bzl flag is now a no-op.
-   Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    \--instrument_test_targets.
-   The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
-   The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
-   dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
-   Flag --incompatible_objc_provider_remove_compile_info is removed.
See [#&#8203;11359](https://togithub.com/bazelbuild/bazel/issues/11359).
-   Starlark now permits def statements to be nested (closures).
-   native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
-   Starlark now supports lambda (anonymous function) expressions.
-   The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
-   The undocumented ctx.expand feature no longer exists.
-   Make --legacy_dynamic_scheduler a no-op flag.
-   Multiplex persistent workers can now use the JSON protocol.
-   native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
-   Roll back change to have native.existing_rules use list instead
    of tuple.
-   BEP includes test suite expansions.
-   config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
-   Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios\_" + cpu.
-   enforce config_setting visibility. See

[https://github.com/bazelbuild/bazel/issues/12932](https://togithub.com/bazelbuild/bazel/issues/12932)2932
for details.
-   add a flag to build v4 signature file
-   Added \_direct_source_jars output group to Java related targets.
    END_PUBLIC
- pkg_deb is no longer part of
@&#8203;bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
-   Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
-   Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
-   Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
-   BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
-   In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
-   The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
-   Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
-   runfiles.merge() and merge_all() now respect
    \--nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
-   Bazel will no longer create a bazel-out symlink if
    \--symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    \--experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
-   Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
-   Simplify build failure output by always using `NNN arguments`.
-   trim_test_configuration now defaults to on
-   Mark genrule.srcs as a source attribute for coverage.
-   When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
-   cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
-   Sign apks deterministically.
-   Make gcov optional in cc_toolchain tools.
-   If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
-   Remove java_lite_proto_library.strict_deps attribute.
-   Generate proguard configurations deterministically.
-   Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
-   Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
-   If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
-   Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
-   Remove obsolete --incompatible_prohibit_aapt1
-   The minimum Android build tools version for the Android rules is
    now 30.0.0
-   Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
-   \--experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
-   Forward coverage-instrumented files from non-tool dependencies by
    default.
-   The used_heap_size_post_build field in BEP is populated when the
    \--memory_profile flag is set
-   \--run_validations defaults to true.
-   Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
-   Remove flag
    \--experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
-   When using MemoryProfiler with multiple GCs via the
    \--memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
-   \--bep_publish_used_heap_size_post_build is deprecated. Use
    \--memory_profile=/dev/null instead.
-   Disable --all_incompatible_changes flag.
-   The --all_incompatible_changes flag is now a no-op
-   The `--toolchain_resolution_debug` flag now accepts regexes
    matching targets, as well as toolchain types, when choosing what
    debug messages to print.
-   Adds --experimental_existing_rules_immutable_view flag to make the
    native.existing_rule and native.existing_rules functions more
    efficient by
    returning immutable, lightweight dict-like view objects instead
    of mutable
    dicts.
-   Add support to length-delimited protos as undeclared output
    annotations \[]
-   The deprecated "relative_to_caller_repository" parameter has been
    removed from the Label constructor.
-   The toolchain transition is now enabled for all toolchains.
-   incompatible_disable_depset_items is flipped
-   The --experimental_existing_rules_immutable_view flag has been
    renamed to  --incompatible_existing_rules_immutable_view
-   Bazel no longer supports Java 8. From this version on, the
    minimum required JDK is OpenJDK 11.
-   alias() can now select() directly on constraint_value()

Fixes
[https://github.com/bazelbuild/bazel/issues/13047](https://togithub.com/bazelbuild/bazel/issues/13047).

Closes
[#&#8203;14310](https://togithub.com/bazelbuild/bazel/issues/14310).
-   Fixed an issue where Bazel could erroneously report a test passes
    in coverage mode without actually running the test.
-   Make protocOpts() publicly accessible.
-   Add coverage configuration fragment, used to expose
    output_generator label.
-   Bazel now no longer includes system headers on macOS in coverage
reports
([#&#8203;14969](https://togithub.com/bazelbuild/bazel/issues/14969)).

Closes
[#&#8203;14971](https://togithub.com/bazelbuild/bazel/issues/14971).
-   Starlark test rules can use the new inherited_environment
    parameter of testing.TestEnvironment to specify environment
    variables
    whose values should be inherited from the shell environment.

Closes
[#&#8203;14849](https://togithub.com/bazelbuild/bazel/issues/14849).
-   none
    RELNOTES:none
-   Enable merging permissions during Android manifest merging with
    the --merge_android_manifest_permissions flag.
-   Added new register\_{execution_platforms,toolchains} directives to
    the MODULE.bazel file, to replace the
    {execution_platforms,toolchains}\_to_register attributes on the
    module() directive.
-   Add support for fetching RPC credentials from credential helper.

Progress on
[https://github.com/bazelbuild/bazel/issues/15856](https://togithub.com/bazelbuild/bazel/issues/15856)

Closes
[#&#8203;15947](https://togithub.com/bazelbuild/bazel/issues/15947).
-   `cquery`'s new output mode
    [`--output=files`](https://bazel.build/docs/cquery#files-output)
    lists the output files of the targets matching the query. It
    takes the current value of `--output_groups` into account.

Closes
[#&#8203;15552](https://togithub.com/bazelbuild/bazel/issues/15552).
-   Fix for desugaring failure on Bazel+Android+Windows build
    scenario.

     [4.2.3] Update GrpcRemoteDownloader to only include relevant
     headers. (#16450) (#16459)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes #16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

     [4.2.4] Bump minimum supported macOS versions to 10.13 (#18047)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes #16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

     [4.2.4] Bump minimum supported macOS versions to 10.13 (#18047)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes #16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    #12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Release 7.0.0-pre.20230417.1 (2023-04-25)
a333dc1 
Baseline: 0a47a1f

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    #7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
  - Native libraries in data attribute are not collected. See
    #13550 for details
  - Enforce the `--profile` path to be absolute.
  - Enforce the --memory_profile path to be absolute.
  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
  - --apple_sdk has been deleted.  It is a no-op.
  - --bep_publish_used_heap_size_post_build is now a no-op and will
    be deleted in a future release. Use --memory_profile=/dev/null
    instead.
  - Flipped --incompatible_disallow_resource_jars (see
    #13221).
  - Remove --bep_publish_used_heap_size_post_build
  - JSON trace profile: rename counter names.
  - Removed --action_graph from the dump command.
  - Remove `--{experimental_,}json_trace_compression` option.
  - Remove `--experimental_profile_cpu_usage`.
  - flipped --incompatible_java_common_parameters (see #12373)
  - this incompatible change breaks old instances of http_archive
    that specified netrc as an absolute path. It is unlikely there
    are many instances in the wild since the path would refer to a
    netrc file inside the external repository by absolute path.
    Migration should be straightforward.
  - genrule switched to use exec transition instead of host. This can
    break targets with hardcoded output paths. To avoid using
    hardcoded paths use make variables, see
    https://docs.bazel.build/versions/4.2.2/be/make-variables.html#pre
    defined_label_variables
  - this incompatible change breaks old instances of http_archive
    that specified netrc as an absolute path. It is unlikely there
    are many instances in the wild since...
  - Error Prone now checks for unused return values of additional
    methods on `java.lang.Object`, which can be disabled using
    `--javacopts=-Xep:ReturnValueIgnored:OFF`
  - Error Prone now checks for unused return values of additional
    methods on `java.lang.Object`, which can be disabled using
    `--javacopts=-Xep:ReturnValueIgnored:OFF`
  - The --incompatible_existing_rules_immutable_view flag has been
    flipped to true. See
    #13907 for
    migration notes.
  - Split up the C++ archive from the C++ link action and set
    `CppArchive` as mnemonic.
  - workspace(managed_directories=) is not available anymore.
  - --legacy_important_outputs now has a default of false.
  - --legacy_important_outputs default reverted to true.
  - objc_library now requires CcInfo in its deps.  If this breaks
    you, add empty CcInfo() to your rule.
  - Flag --experimental_local_memory_estimate removed.
  - Added a new flag
    --incompatible_unambiguous_label_stringification, which causes
    labels in the main repo to stringify into unambiguous forms
    starting with an @. See
    #15916 for more
    information.
  - analysis_test moved into testing.analysis_test
  - Flip incompatible_enable_cc_toolchain_resolution
    (#7260)
  - (Rollback) Flip incompatible_enable_cc_toolchain_resolution
    (#7260)
  - name parameter is removed from rule call
    (#16301)
  - name parameter is removed from rule call
    (#16301)
  - name parameter is removed from rule call
    (#16301)
  - --incompatible_remote_downloader_send_all_headers is flipped to
    true. See #16356 for details.
  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.
  - In package_group's `packages` attribute, the syntax "//..." now
    refers to all packages in the same repository as the package
    group, rather than all packages everywhere. The new item "public"
    can be used instead to obtain the old behavior. In `bazel query
    --output=proto` (and `--output=xml`), the `packages` attribute
    now serializes with the leading double slash included (for
    instance, `//foo/bar/...` instead of `foo/bar/...`). See also
    #16355, #16323, and #16391.
  - This has the side effect of changing the message on unsuccessful
    builds from
    ```
    FAILED: Build did NOT complete successfully (0 packages loaded)
    ```
    to
    ```
    ERROR: Build did NOT complete successfully
    ```
  - Bazel no longer increases the delay between progress updates when
    there is no cursor control.
  - This has the side effect of changing the message on unsuccessful
    builds from
    ```
    FAILED: Build did NOT complete successfully (0 packages loaded)
    ```
    to
    ```
    ERROR: Build did NOT complete successfully
    ```
  - the --experimental_async_execution flag is now a no-op.
  - --experimental_replay_action_out_err is not a no-op.
  - `cquery --output=files` also outputs source files.
  - `--incompatible_strict_conflict_checks` is flipped to true. See
    #16729 for details.
  - `--incompatible_strict_conflict_checks` is flipped to true. See
    #16729 for details.
  - `--incompatible_always_include_files_in_data` is flipped to true.
    See #16654 for details.
  - This changes the behavior of Python version in exec/host
    configuration. Mitigation is to set Python version on the targets.
  - When multiple --deleted_packages options are passed on the
    command line, they will be concatenated instead of the latest one
    taking effect.
  - This has the side effect of changing the message on unsuccessful
    builds from
  - JSON profile: Use doubles instead of strings for counter series.
  - query --output=proto --order_output=deps now returns targets in
    topological order (previously there was no ordering).
  - --experimental_build_transitive_python_runfiles is flipped to
    false. See #16303 for details
  - --incompatible_python_disable_py2 is flipped to true. See #17293
    for details.
  - When remote cache evicts blobs, Bazel will exit with code 39.
  - `--features` only applies to targets built in the target
    configuration, and `--host_features` is used for the host / exec
    configuration (gated behind `--incompatible_use_host_features`)
  - `--incompatible_strict_conflict_checks` is flipped to true. See
    #16729 for details.
  - Bazel's local CPU resource on Linux is now container aware. Use
    `--local_cpu_resources`, `--loading_phase_threads` or `--jobs` to
    override.
  - `copy_from_rule` is exec_groups is deprecated
    (#17668).
  - --legacy_bazel_java_test is now a no-op
  - --legacy_bazel_java_test is now a no-op
  - --legacy_bazel_java_test is now a no-op
  - `--experimental_execution_graph_log` no longer exists. Current
    users that want local logs need to pass
    `--experimental_enable_execution_graph_log
    --experimental_execution_graph_log_path=/some/local/path`.
    Current users that want logs uploaded to BEP need to pass
    `--experimental_enable_execution_graph_log
    --experimental_stream_log_file_uploads`.
  - Remove 'darwin' as a CPU value, use 'darwin_x86_64' instead
  - Remove high priority workers functionality from blaze.

New features:

  - Args.add_all and Args.add_joined can now accept closures in
    map_each if explicitly enabled via allow_closure.
  - Add `--bes_header` flag to pass extra headers to the BES server.
  - Support local_repository in Bazel Registry's source.json file
  - The `aquery` and `cquery` commands now respect the
    `--query_file` flag just like the `query` command.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    #10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See #11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    #12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
  - Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
  - Remove obsolete --incompatible_prohibit_aapt1
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
  - --experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
  - Forward coverage-instrumented files from non-tool dependencies by
    default.
  - The used_heap_size_post_build field in BEP is populated when the
    --memory_profile flag is set
  - --run_validations defaults to true.
  - Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
  - Remove flag
    --experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
  - When using MemoryProfiler with multiple GCs via the
    --memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
  - --bep_publish_used_heap_size_post_build is deprecated. Use
    --memory_profile=/dev/null instead.
  - Disable --all_incompatible_changes flag.
  - The --all_incompatible_changes flag is now a no-op
  - The `--toolchain_resolution_debug` flag now accepts regexes
    matching targets, as well as toolchain types, when choosing what
    debug messages to print.
  - Adds --experimental_existing_rules_immutable_view flag to make the
    native.existing_rule and native.existing_rules functions more
    efficient by
    returning immutable, lightweight dict-like view objects instead
    of mutable
    dicts.
  - Add support to length-delimited protos as undeclared output
    annotations []
  - The deprecated "relative_to_caller_repository" parameter has been
    removed from the Label constructor.
  - The toolchain transition is now enabled for all toolchains.
  - incompatible_disable_depset_items is flipped
  - The --experimental_existing_rules_immutable_view flag has been
    renamed to  --incompatible_existing_rules_immutable_view
  - Bazel no longer supports Java 8. From this version on, the
    minimum required JDK is OpenJDK 11.
  - Deprecate --incompatible_applicable_licenses flag, in preparation
    for removal in Bazel 6.x.
  - Treat py_*.srcs_version="PY2" the same as "PY2ONLY".
  - The Build Event Protocol now contains file digests and sizes
    along with the file name and URI.
  - Refactor system suspend event handling.
  - alias() can now select() directly on constraint_value()
  - Allow \a \b \f \v escape sequences in Starlark.
  - Match remote and local xcode version by most granular version.
  - Adds `--experimental_worker_multiplex_sandboxing` flag that
    controls whether to sandbox multiplex workers that support it.
  - provider() has a new parameter: init, a callback for performing
    pre-processing and validation of field values. Iff this parameter
    is set,
    provider() returns a tuple of 2 elements: the usual provider
    symbol (which,
    when called, invokes init) and a raw constructor (which bypasses
    init).
  - Tests that fail to create or complete their
    `TestAttemptContinuation` by
    throwing an `ExecException` will report an `INCOMPLETE` status.
    Previously, Bazel
    would fail to report any status for the test attempt.
  - Fixed an issue where Bazel could erroneously report a test passes
    in coverage mode without actually running the test.
  - Include more information about configurations in cquery proto
    formatted output. This deprecates the configuration field of
    AnalysisProtosV2.ConfiguredTarget, and adds a new field,
    configuration_id, to
    be used instead.
  - experimental cc_library.implementation_deps inverted to
    interface_deps
  - In aquery and cquery proto output, indicate if a configuration is
    a
    tool or non-tool configuration.
  - Include complete configurations in cquery proto output.
  - experimental cc_library.implementation_deps inverted to
    interface_deps
  - Make protocOpts() publicly accessible.
  - Add some documentation about how configuration information is
    conveyed in cquery proto output.
  - Introduces experimental static library linking API under
    apple_common.link_multi_arch_static_library
  - Further deprecation and removal of pkg_tar. Stop supporting
    legacy use of 'files' attribute, where it could be a list of
    labels instead of a map of paths to labels.
  - Removed --incompatible_no_build_defs_pkg flag. It never fulfilled
    its purpose because --all_incompatible_changes would never set
    it. The last rule it gated (pkg_tar) is scheduled to be removed
    in Bazel 6.x.
  - Add coverage configuration fragment, used to expose
    output_generator label.
  - Bazel now no longer includes system headers on macOS in coverage
    reports (#14969).
  - android_sdk_repository read $ANDROID_SDK_ROOT in addition to
    $ANDROID_HOME.
  - The default dexer is now d8. dx can be optionally enabled using:
      --define=android_dexmerger_tool=dx_dexmerger \
      --define=android_incremental_dexing_tool=dx_dexbuilder \
      --define=android_standalone_dexing_tool=dx_compat_dx \
      --use_workers_with_dexbuilder
  - Packaging support for deploy JAR embedded JDK files (hermetic
    Java).
  - Don't stamp cc_common.link actions for tool dependencies.
  - Starlark test rules can use the new inherited_environment
    parameter of testing.TestEnvironment to specify environment
    variables
    whose values should be inherited from the shell environment.
  - Enable merging permissions during Android manifest merging with
    the --merge_android_manifest_permissions flag.
  - Allow specialization to work with constraint_values.
  - Bazel uses the D8 jar from Maven instead of the SDK.
  - Make ijar / java_import preserve classes with `@kotlin.Metadata`
    annotations
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather than always linking statically when Windows is
    the _host_).
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather than always linking statically when Windows is
    the _host_).
  - Add devtools/build/lib/worker:work_request_handlers to the remote
    android tools release package. This will be transitively packaged
    into all_android_tools.
  - Bazel uses the D8 jar from Maven instead of the SDK.
  - android_sdk_repository read $ANDROID_SDK_ROOT in addition to
    $ANDROID_HOME.
  - Advance android_tools_pkg version to 0.24.0.
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather
    than always linking statically when Windows is the _host_).
  - Bazel uses the D8 jar from Maven instead of the SDK.
  - "blaze config" now only reports info from the last build. To
    compare configurations across multiple builds, redirect "blaze
    config" output to a file and run your favorite diff tool.
  - The --incompatible_override_toolchain_transition flag is now
    always set, and will be removed in the future. Thus,
    --noincompatible_override_toolchain_transition has no effect, and
    the value of the incompatible_use_toolchain_transition parameter
    in aspect() and rule() builtins is ignored.
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather
    than always linking statically when Windows is the _host_).
  - Toolchain types may now be optional, in addition to mandatory.
    See https://bazel.build/docs/toolchains#optional-toolchains for
    further details.
  - Add six to deps of has_services=1 py_proto_librarys.
  - pkg_tar(symlinks) has been removed. Users needing that feature
    should
    migrate to @rules_pkg.
  - Aspects can now define and use exec groups using the same API as
    rules.
  - Removed the obsolete --incompatible_applicable_licenses flag. The
    feature is permanently enabled.
  - embedded_tools packages R8 desugarer again
  - Bazel now selects sh path based on execution platform instead of
    host platform, making it possible to execute sh actions in
    multiplatform builds. --shell_executable now only applies to
    actions configured for host.
  - labels in genquery.scope are no longer configured.
  - When Bzlmod is enabled, all Bzlmod-generated repos will have an
    extra '@' prepended to their names. This effectively enables the
    canonical label literal syntax for Bzlmod-generated repos
    (`@@canonicalRepoName//pkg:target`; see
    https://docs.google.com/document/d/1N81qfCa8oskCk5LqTW-LNthy6EBrDo
    t7bdUsjz6JFC4/edit?usp=sharing).
  - Exposed `CcSharedLibraryInfo` to Starlark builtins.
  - Enable --use_top_level_targets_for_symlinks by default.
  - Singlejar accepts runtime Created-By field
  - --noincompatible_disable_managed_directories, and with that,
    workspace(managed_directories=) is not supported anymore.
  - Bazel supports D8 desugaring, albeit without persistent workers
  - Remove mtime options from pkg_tar. Users should migrate to
    @rules_pkg.
  - Test for experimental multiplexed persistent resource processor.
  - Added new register_{execution_platforms,toolchains} directives to
    the MODULE.bazel file, to replace the
    {execution_platforms,toolchains}_to_register attributes on the
    module() directive.
  - The legacy pkg_tar no longer supports the ability to untar and
    repackage an input tar file (`deps` attribute). Users needed that
    capability must switch to github.com/bazelbuild/rules_pkg.
  - `cquery`'s new output mode
    [`--output=files`](https://bazel.build/docs/cquery#files-output)
    lists the output files of the targets matching the query. It
    takes the current value of `--output_groups` into account.
  - Change singlejar metadata to report Created-By Bazel
  - Add support for fetching RPC credentials from credential helper.
  - Revert interface_deps back to implementation_deps after problem
    reported in. Use `buildozer 'rename deps implementation_deps'
    //...:%cc_library; buildozer 'rename interface_deps deps'
    //...:%cc_library`
  - Fix for desugaring failure on Bazel+Android+Windows build
    scenario.
  - D8 is the default desugarer
  - Migrate main_dex_list_creator to D8 (DX deprecation)
  - --experimental_enable_bzlmod has been renamed --enable_bzlmod,
    and still defaults to false.
  - selects() no longer produce irrelevant duplicate label checks
  - Adds a dexer output cache to CompatDexBuilder to improve build
    speed.
  - Improved error messages when analyzing inline bzl code
  - Improved error messages when analyzing inline bzl code
  - The `@bazel_tools//tools/cpp:compiler` flag now has the value
    `gcc` if the configured compiler is detected to be gcc rather
    than the generic value `compiler`. A branch for `gcc` may have to
    be added to `select` statements that do not have a default case
    that handles gcc appropriately.
  - The `get_child` method of `path` now accepts an arbitrary
    number of relative path strings as positional arguments.
  - SourceManifestAction supports `Action.content`
  - Add --incompatible_build_transitive_python_runfiles alias. See
    #16303
  - The @bazel_tools//tools/cpp:compiler flag now has the value
    `clang` for the auto-configured Xcode toolchain rather than the
    generic value compiler. A branch for `clang` may have to be added
    to select statements that do not have a default case that handles
    this toolchain appropriately.
  - added additional debug message to warn of skipped toolchains
    during resolution
  - The deprecated --remote_allow_symlink_upload flag has been
    removed. Symlinks in local action outputs are always permitted,
    even with remote caching. Whether they're uploaded as symlinks or
    as the files/directories they point to is still determined by the
    --incompatible_remote_symlinks flag.
  - Added `struct`, `json`, `proto`, and `depset` to the starlark
    environment of Bazel's cquery (--output=starlark) command
  - Added three `package_group`-related flags:
    `--incompatible_package_group_includes_double_slash` (#16391),
    `--incompatible_package_group_has_public_syntax` (#16355), and
    `--incompatible_fix_package_group_reporoot_syntax` (#16323). With
    these flags, `package_group` can now easily specify "all
    packages", "no packages", and "all packages in the current repo".
  - Record hermetic packaged JDK modules file size in deploy JAR
    manifest 'JDK-Lib-Modules-Size' attribute.
  - .bzl files may now set a visibility to guard what other .bzl and
    BUILD files may load them. See [...] for more information.
  - Deletes the --extra_proguard_specs Blaze flag
  - The new path variable `$(rlocationpath ...)` and its plural form
    `$(rlocationpaths ...)` can be used to expand labels to the paths
    accepted by the `Rlocation` function of runfiles libraries. This
    is the preferred way to access data dependencies at runtime and
    works on all platforms, even when runfiles are not enabled (e.g.,
    on Windows by default).
  - Starlark `print()` statements are now emitted iff the line of
    code is executed. They are no longer replayed on subsequent
    invocations unless the Starlark code is re-executed.
    Additionally, multiple identical `print()` statements (same
    string from the same line of code, e.g. from a loop) are all
    emitted and no longer deduplicated.
  - Fixes a bug where some compilation flags would not be applied to
    a cc_test
  - removed outdated ctx.host_fragments
  - removed outdated ctx.host_configuration
  - Now that the host configuration is finished, `genrule` should
    prefer the use of `tools` and stop using `exec_tools`.
  - Added a `native.package_relative_label()` function, which
    converts a label string to a Label object in the context of the
    calling package, in contrast to `Label()`, which does so in the
    context of the current .bzl file. Both functions now also accept
    relative labels such as `:foo`, and are idempotent.
  - Update Android manifest merger to v30.1.3, and also drop support
    for legacy (pre-D8) desugaring.
  - Adds coverage metric support to android_local_test
  - Correctly encode double value positive infinity as "inf" instead
    of "+inf" for textprotos.
  - Add --use_target_platform_for_tests which uses the target
    platform for executing tests instead of the execution platform.
  - Custom C++ rules on Windows calling
    cc_common.create_linking_context_from_compilation_outputs should
    review whether each target of the rule type should produce a
    dynamic library since a condition which blocked their creation
    has been moved to the rules from behind the API.
  - Add flag `--experimental_remote_cache_ttl` and set the default
    value to 3 hours.
  - making --incompatible_use_platforms_repo_for_constraints do
    nothing. Using constraints from @bazel_tools//platforms with or
    without the flag will throw error with message "Constraints from
    @bazel_tools//platforms have been removed. Please use constraints
    from @platforms repository embedded in Bazel, or preferably
    declare dependency on https://github.com/bazelbuild/platforms"
  - Fixed an issue where WORKSPACE and WORKSPACE-loaded .bzl files
    couldn't see the Bzlmod root module's mappings when Bzlmod is
    enabled.
  - Subsequent settings of --extra_execution_platforms now override
    previous settings, instead of adding them to a list. If you
    currently set --extra_execution_platforms more than once, please
    migrate by passing a list of values to
    --extra_execution_platforms instead so that earlier values aren't
    overwritten.
  - @bazel_tools//config:common_settings.bzl has been removed.
    Use @bazel_skylib//rules:common_settings.bzl instead.
  - cc_shared_library is no longer experimental, see
    #16709 for details
  - The flag `--distinct_host_configuration` is removed. It has been
    a no-op since Bazel 6.0.0.
  - Added `native.module_name()` and `native.module_version()` to
    allow BUILD macro authors to acquire information about which
    Bazel module the current repo is associated with.
  - Add `--skip_incompatible_explicit_targets` option
  - Remove 'darwin' as a CPU value, use 'darwin_x86_64' instead
  - cc_test can now be configured by using a native.toolchain().
  - `@foo` labels can now be used on the command line as the
    top-level target (that is, `bazel build @foo` now works).
    Double-dot syntax is now forbidden (`bazel build ../foo` will no
    longer work).
  - The location of rules that explicitly specify `generator_name`
    and/or `generator_function` attributes (typically because they
    are incidentally copied from `native.existing_rule()`) is now the
    top-level call in the `BUILD` file, which is consistent with
    rules that do not explicitly specify these attributes.
  - Warnings (most notably those associated with the `deprecation`
    rule attribute) are no longer replayed on subsequent invocations
    unless the target in question is re-analyzed. Warnings are purely
    informational, so this change has no bearing on the correctness
    of the build. Downstream tests that break due to this change
    should update their expectations.
  - `--experimental_remote_build_event_upload` has been renamed to
    `--remote_build_event_upload`
  - [Breaking change] platform, constraint_setting, and
    constraint_value can no longer take an applicable_licenses value.
    Remediation is to remove the attribute and rely on the package
    level default.
  - `--experimental_action_cache_store_output_metadata` has been
    renamed to `--action_cache_store_output_metadata`
  - Changed the default value for `--remote_build_event_upload` to
    `minimal`.
  - `--experimental_remote_cache_compression` has been renamed to
    `--remote_cache_compression`
  - The REPO.bazel and MODULE.bazel files are now also considered
    workspace boundary markers.

Hey, uh, guys...I definitely have config_setttings with unset visibility that aren't erroring when used from selects() outside their packages. That's unexpected, right?

(True with --incompatible_enforce_config_setting_visibility and on bazel rolling 7.0.0-pre.20230426.1.)

This migration is confusing (sorry) because there are two flags.

--incompatible_enforce_config_setting_visibility is already set to default at head. With that flag every config_setting is public unless it specifically overrides.

#12933 changes the default to private. This is not yet flipped at head. As I understand from the comment thread @keertk is working through CI fixups.

Sorry--on a second read, I'm realizing you'd said above. Sorry for the false alarm, Greg, and thanks as always for being patient, informative, and great.

In recompense, I'll work to make sure our deps (like rules_boost, where I have a commit bit) all work with it and update the issue that brought me here.

Release 4.2.4 (2023-04-20)
8919977 
Baseline: 37a429a

Cherry picks:

   + a689d67:
     Use getRunfilesPath for run_under executable path generation.
     getRootRelativePath doesn't return a valid runfiles path for
     external source files anymore after the recent external source
     root change. Also, it won't work for external labels either once
     the --nolegacy_external_runfiles becomes default. This fixes
     issue bazelbuild#12545.
   + d90ec67:
     Fix NPE when coveragerunner is not set on the toolchain.
   + 8555789:
     Fix the classic query package-loading cutoff optimization with
     external workspaces.
   + d113d74:
     Update turbine
   + 1489f0f:
     Support Scala3 .tasty files
   + 0d2d95c:
     Update to java_tools javac11 release 10.5 (bazelbuild#12647)
   + a9419f3:
     Fix common prefix for instrumentation filter
   + 84fadcf:
     Fix builds for filegroup targets with incompatible dependencies
   + e43825d:
     Revert "Remove
     --incompatible_blacklisted_protos_requires_proto_info"
   + 082d58d:
     Transform roots along with paths during output deletion.
   + e8835c1:
     AttributeContainer.Large now handles more than 127 attributes.
   + e1e8734:
     Add an env attribute to all test and binary rule classes
   + a87d7ed:
     Take no action to prefetch empty artifacts.
   + 3e969ff:
     Fix a couple of bugs with Incompatible Target Skipping

   + 1962a59:
     Fix the case where if all strategies for one branch of `dynamic`
     execution fail to accept (that is, refuse to even take) the

     [4.2.4] Bump minimum supported macOS versions to 10.13 (bazelbuild#18047)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes bazelbuild#16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Incompatible changes:

  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.

    Closes bazelbuild#16439.

Important changes:

  - Multiplex persistent workers can now use the JSON protocol.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)

Release 7.0.0-pre.20230417.1 (2023-04-25)
e5e597f 
Baseline: 0a47a1f

Incompatible changes:

  - Removing java_common.javac_jar Starlark call.
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change
    because there is some code that relies on the precise type
    returned, including brittle workarounds for this bug specifically
    and insufficiently flexible workarounds for other issues with the
    intersection of select and native.existing_rule.
  - flipped incompatible_use_toolchain_resolution_for_java_rules, see
    bazelbuild#7849
  - Query output=xml/proto/location for source files will now show
    the location of line 1 of the source file (as the new default)
    instead of its location in the BUILD file.
  - Specifying a target pattern underneath a directory specified by
    .bazelignore will now emit a warning, not an error.
  - Query `--order_output=auto` will now sort lexicographically.
    However, when `somepath` is used as a top level function (e.g.
    `query 'somepath(a, b)'`), it will continue to output in
    dependency order. If you do not want the lexicographical output
    ordering, specify another `--order_output` value (`no`, `deps` or
    `full`) based on what ordering you require.
  - In the build event stream,
    BuildMetrics.TargetMetrics.targets_loaded is no longer populated.
    Its value was always mostly meaningless.
    BuildMetrics.TargetMetrics.targets_configured and
    BuildMetrics.ActionSummary.actions_created now include configured
    aspect data.
  - //visibility:legacy_public has been removed.
  - Flip and remove incompatible_dont_collect_so_artifacts
    (bazelbuild#13043).
  - Remove flag --experimental_no_product_name_out_symlink: it is
    always true.
  - The Starlark method generate_dsym in objc fragment has
    been deleted.  Please use the equivalent apple_generate_dsym in
    cpp
    fragment instead.
  - Native libraries in data attribute are not collected. See
    bazelbuild#13550 for details
  - Enforce the `--profile` path to be absolute.
  - Enforce the --memory_profile path to be absolute.
  - JavaToolchainInfo.jvm_opt returns Depset instead of a list.
  - --apple_sdk has been deleted.  It is a no-op.
  - --bep_publish_used_heap_size_post_build is now a no-op and will
    be deleted in a future release. Use --memory_profile=/dev/null
    instead.
  - Flipped --incompatible_disallow_resource_jars (see
    bazelbuild#13221).
  - Remove --bep_publish_used_heap_size_post_build
  - JSON trace profile: rename counter names.
  - Removed --action_graph from the dump command.
  - Remove `--{experimental_,}json_trace_compression` option.
  - Remove `--experimental_profile_cpu_usage`.
  - flipped --incompatible_java_common_parameters (see bazelbuild#12373)
  - this incompatible change breaks old instances of http_archive
    that specified netrc as an absolute path. It is unlikely there
    are many instances in the wild since the path would refer to a
    netrc file inside the external repository by absolute path.
    Migration should be straightforward.
  - genrule switched to use exec transition instead of host. This can
    break targets with hardcoded output paths. To avoid using
    hardcoded paths use make variables, see
    https://docs.bazel.build/versions/4.2.2/be/make-variables.html#pre
    defined_label_variables
  - this incompatible change breaks old instances of http_archive
    that specified netrc as an absolute path. It is unlikely there
    are many instances in the wild since...
  - Error Prone now checks for unused return values of additional
    methods on `java.lang.Object`, which can be disabled using
    `--javacopts=-Xep:ReturnValueIgnored:OFF`
  - Error Prone now checks for unused return values of additional
    methods on `java.lang.Object`, which can be disabled using
    `--javacopts=-Xep:ReturnValueIgnored:OFF`
  - The --incompatible_existing_rules_immutable_view flag has been
    flipped to true. See
    bazelbuild#13907 for
    migration notes.
  - Split up the C++ archive from the C++ link action and set
    `CppArchive` as mnemonic.
  - workspace(managed_directories=) is not available anymore.
  - --legacy_important_outputs now has a default of false.
  - --legacy_important_outputs default reverted to true.
  - objc_library now requires CcInfo in its deps.  If this breaks
    you, add empty CcInfo() to your rule.
  - Flag --experimental_local_memory_estimate removed.
  - Added a new flag
    --incompatible_unambiguous_label_stringification, which causes
    labels in the main repo to stringify into unambiguous forms
    starting with an @. See
    bazelbuild#15916 for more
    information.
  - analysis_test moved into testing.analysis_test
  - Flip incompatible_enable_cc_toolchain_resolution
    (bazelbuild#7260)
  - (Rollback) Flip incompatible_enable_cc_toolchain_resolution
    (bazelbuild#7260)
  - name parameter is removed from rule call
    (bazelbuild#16301)
  - name parameter is removed from rule call
    (bazelbuild#16301)
  - name parameter is removed from rule call
    (bazelbuild#16301)
  - --incompatible_remote_downloader_send_all_headers is flipped to
    true. See bazelbuild#16356 for details.
  - GrpcRemoteDownloader only includes relevant headers instead of
    sending all credentials.
  - In package_group's `packages` attribute, the syntax "//..." now
    refers to all packages in the same repository as the package
    group, rather than all packages everywhere. The new item "public"
    can be used instead to obtain the old behavior. In `bazel query
    --output=proto` (and `--output=xml`), the `packages` attribute
    now serializes with the leading double slash included (for
    instance, `//foo/bar/...` instead of `foo/bar/...`). See also
    bazelbuild#16355, bazelbuild#16323, and bazelbuild#16391.
  - This has the side effect of changing the message on unsuccessful
    builds from
    ```
    FAILED: Build did NOT complete successfully (0 packages loaded)
    ```
    to
    ```
    ERROR: Build did NOT complete successfully
    ```
  - Bazel no longer increases the delay between progress updates when
    there is no cursor control.
  - This has the side effect of changing the message on unsuccessful
    builds from
    ```
    FAILED: Build did NOT complete successfully (0 packages loaded)
    ```
    to
    ```
    ERROR: Build did NOT complete successfully
    ```
  - the --experimental_async_execution flag is now a no-op.
  - --experimental_replay_action_out_err is not a no-op.
  - `cquery --output=files` also outputs source files.
  - `--incompatible_strict_conflict_checks` is flipped to true. See
    bazelbuild#16729 for details.
  - `--incompatible_strict_conflict_checks` is flipped to true. See
    bazelbuild#16729 for details.
  - `--incompatible_always_include_files_in_data` is flipped to true.
    See bazelbuild#16654 for details.
  - This changes the behavior of Python version in exec/host
    configuration. Mitigation is to set Python version on the targets.
  - When multiple --deleted_packages options are passed on the
    command line, they will be concatenated instead of the latest one
    taking effect.
  - This has the side effect of changing the message on unsuccessful
    builds from
  - JSON profile: Use doubles instead of strings for counter series.
  - query --output=proto --order_output=deps now returns targets in
    topological order (previously there was no ordering).
  - --experimental_build_transitive_python_runfiles is flipped to
    false. See bazelbuild#16303 for details
  - --incompatible_python_disable_py2 is flipped to true. See bazelbuild#17293
    for details.
  - When remote cache evicts blobs, Bazel will exit with code 39.
  - `--features` only applies to targets built in the target
    configuration, and `--host_features` is used for the host / exec
    configuration (gated behind `--incompatible_use_host_features`)
  - `--incompatible_strict_conflict_checks` is flipped to true. See
    bazelbuild#16729 for details.
  - Bazel's local CPU resource on Linux is now container aware. Use
    `--local_cpu_resources`, `--loading_phase_threads` or `--jobs` to
    override.
  - `copy_from_rule` is exec_groups is deprecated
    (bazelbuild#17668).
  - --legacy_bazel_java_test is now a no-op
  - --legacy_bazel_java_test is now a no-op
  - --legacy_bazel_java_test is now a no-op
  - `--experimental_execution_graph_log` no longer exists. Current
    users that want local logs need to pass
    `--experimental_enable_execution_graph_log
    --experimental_execution_graph_log_path=/some/local/path`.
    Current users that want logs uploaded to BEP need to pass
    `--experimental_enable_execution_graph_log
    --experimental_stream_log_file_uploads`.
  - Remove 'darwin' as a CPU value, use 'darwin_x86_64' instead
  - Remove high priority workers functionality from blaze.

New features:

  - Args.add_all and Args.add_joined can now accept closures in
    map_each if explicitly enabled via allow_closure.
  - Add `--bes_header` flag to pass extra headers to the BES server.
  - Support local_repository in Bazel Registry's source.json file
  - The `aquery` and `cquery` commands now respect the
    `--query_file` flag just like the `query` command.

Important changes:

  - Flag --incompatible_objc_compile_info_migration is removed.  See
    bazelbuild#10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    bazelbuild#10854.
  - Flag --incompatible_objc_compile_info_migration is removed.  See
    bazelbuild#10854.
  - none
    PAIR=cmita
  - The --incompatible_load_python_rules_from_bzl flag is now a no-op.
  - Filter all (instead of just C++) source files for coverage output
    according to --instrumentation_filter and
    --instrument_test_targets.
  - The `--incompatible_disable_native_apple_binary_rule` flag has
    been added which disables the native `apple_binary` rule. Users
    who need to use `apple_binary` directly (if they cannot use one
    of the more specific Apple rules) should load it from
    https://github.com/bazelbuild/rules_apple.
  - The Android rules' --use_singlejar_apkbuilder is now a no-op.
    SingleJar will always be used to build APKs.
  - dict.setdefault(key, ...) now fails if dict is frozen, even if it
    already contains key. This is an incompatible API change.
  - Flag --incompatible_objc_provider_remove_compile_info is removed.
     See bazelbuild#11359.
  - Starlark now permits def statements to be nested (closures).
  - native.existing_rule now returns select values in a form that is
    accepted by rule instantiation. This is a breaking API change,
    though the fallout is expected to be small.
  - Starlark now supports lambda (anonymous function) expressions.
  - The "test" and "coverage" commands no longer return 3 when a
    test action fails because of a system error. Instead, the exit
    code
    reflects the type of system error.
  - The undocumented ctx.expand feature no longer exists.
  - Make --legacy_dynamic_scheduler a no-op flag.
  - Multiplex persistent workers can now use the JSON protocol.
  - native.existing_rule now returns a mutable list, not a tuple, for
    a list-valued attributes. This is an incompatible API change.
  - Roll back change to have native.existing_rules use list instead
    of tuple.
  - BEP includes test suite expansions.
  - config_setting now honors `visibility` attribute (and defaults to
    `//visibility:public`)
  - Change the MultiArchSplitTransitionProvider to be based on
    platform type + CPU instead of fixed "ios_" + cpu.
  - enforce config_setting visibility. See
    bazelbuild#12932 for details.
  - add a flag to build v4 signature file
  - Added _direct_source_jars output group to Java related targets.
    END_PUBLIC
  - pkg_deb is no longer part of @bazel_tools//build_defs/pkg:pkg.bzl.
    Use https://github.com/bazelbuild/rules_pkg/tree/main/pkg instead
  - Allowing the lipo operations to be conditional in the
    linkMultiArchBinary API for Apple binaries. Single architecture
    slices are now returned through AppleBinaryOutput and the
    Starlark API.
  - Release restriction for "-" in the package name for Python
    sources. Now `py_binary` and `py_test` targets can have main
    source file with "-" in the path.
  - Users consuming BEP may assume that a `named_set_of_files` event
    will
    appear before any event referencing that `named_set` by ID. This
    allows consumers
    to process the files for such events (eg. `TargetCompleted`)
    immediately.
  - BEP includes all files from successful actions in requested
    output groups.
    Previously, an output group's files were excluded if any file in
    the output group
    was not produced due to a failing action. Users can expect BEP
    output to be larger
    for failed builds.
  - In BEP, TargetComplete.output_group has a new field `incomplete`
    indicating that the file_sets field is missing one or more
    declared artifacts
    whose generating actions failed.
  - The flag `--toolchain_resolution_debug` now takes a regex
    argument, which is used to check which toolchain types should
    have debug info printed. You may use `.*` as an argument to keep
    the current behavior of debugging every toolchain type.
  - Add runfiles.merge_all() for merging a sequence of runfiles
    objects.
  - runfiles.merge() and merge_all() now respect
    --nested_set_depth_limit.
    If you hit the depth limit because you were calling merge() in a
    loop, use
    merge_all() on a sequence of runfiles objects instead.
  - Bazel will no longer create a bazel-out symlink if
    --symlink_prefix is specified: the directory pointed to via the
    bazel-out symlink is accessible via ${symlink_prefix}-out. If
    this causes problems for you, set
    --experimental_no_product_name_out_symlink=false in your builds
    and file an issue.
  - Updates worker protocol with cancellation fields, and adds
    experimental_worker_cancellation flag to control cancellation.
  - Simplify build failure output by always using `NNN arguments`.
  - trim_test_configuration now defaults to on
  - Mark genrule.srcs as a source attribute for coverage.
  - When using --allow_analysis_failures (for example, via
    bazel-skylib's
    analysistest with `expect_failure = True`), analysis-time
    failures in aspect
    implementation functions will now be propagated and saved in
    AnalysisFailureInfo, just like analysis-time failures in rules.
  - cquery --noimplicit_deps now correctly filters out resolved
    cc_toolchains
  - Sign apks deterministically.
  - Make gcov optional in cc_toolchain tools.
  - If --experimental_prefer_mutual_xcode is passed, Bazel will
    choose the local default (instead of the newest mutually
    available version) if it's available both locally and remotely.
  - Remove java_lite_proto_library.strict_deps attribute.
  - Generate proguard configurations deterministically.
  - Adds a new flag, `--incompatible_enable_cc_test_feature` which
    switches from the use of build variables to the feature of the
    same name.
  - Dropped fragile xz support from built in pkg_tar. Users requiring
    xz
    compression should switch to bazlebuild/rules_pkg.
  - If all strategies of one branch (the local or remote execution
    branch) of the `dynamic` strategy fail to even accept (via the
    response they give from `canExec`) the action, `dynamic` will now
    try to see if the other branch can accept it. (Trying to run it
    and it failing will still cause a failure if it was the first
    result, this is about strategies claiming they can't even try the
    action)
  - Add `disable_annotation_processing` option to
    `java_common.compile`, which disables any annotation processors
    passed to `plugins` or in `exported_plugins` of `deps`
  - Remove obsolete --incompatible_prohibit_aapt1
  - The minimum Android build tools version for the Android rules is
    now 30.0.0
  - Adds --experimental_reuse_sandbox_directories flag to reuse
    already-created non-worker sandboxes with cleanup.
  - --experimental_force_gc_after_build is deprecated and will be
    removed soon. Use --bep_publish_used_heap_size_post_build instead
  - Forward coverage-instrumented files from non-tool dependencies by
    default.
  - The used_heap_size_post_build field in BEP is populated when the
    --memory_profile flag is set
  - --run_validations defaults to true.
  - Consider label_keyed_string_dict attributes when gathering
    instrumented files for coverage.
  - Remove flag
    --experimental_forward_instrumented_files_info_by_default, now
    that this behavior is the default.
  - When using MemoryProfiler with multiple GCs via the
    --memory_profile_stable_heap_parameters flag, we do a more
    precise calculation of heap used at the end of the build. This
    will generally result in lower values.
  - --bep_publish_used_heap_size_post_build is deprecated. Use
    --memory_profile=/dev/null instead.
  - Disable --all_incompatible_changes flag.
  - The --all_incompatible_changes flag is now a no-op
  - The `--toolchain_resolution_debug` flag now accepts regexes
    matching targets, as well as toolchain types, when choosing what
    debug messages to print.
  - Adds --experimental_existing_rules_immutable_view flag to make the
    native.existing_rule and native.existing_rules functions more
    efficient by
    returning immutable, lightweight dict-like view objects instead
    of mutable
    dicts.
  - Add support to length-delimited protos as undeclared output
    annotations []
  - The deprecated "relative_to_caller_repository" parameter has been
    removed from the Label constructor.
  - The toolchain transition is now enabled for all toolchains.
  - incompatible_disable_depset_items is flipped
  - The --experimental_existing_rules_immutable_view flag has been
    renamed to  --incompatible_existing_rules_immutable_view
  - Bazel no longer supports Java 8. From this version on, the
    minimum required JDK is OpenJDK 11.
  - Deprecate --incompatible_applicable_licenses flag, in preparation
    for removal in Bazel 6.x.
  - Treat py_*.srcs_version="PY2" the same as "PY2ONLY".
  - The Build Event Protocol now contains file digests and sizes
    along with the file name and URI.
  - Refactor system suspend event handling.
  - alias() can now select() directly on constraint_value()
  - Allow \a \b \f \v escape sequences in Starlark.
  - Match remote and local xcode version by most granular version.
  - Adds `--experimental_worker_multiplex_sandboxing` flag that
    controls whether to sandbox multiplex workers that support it.
  - provider() has a new parameter: init, a callback for performing
    pre-processing and validation of field values. Iff this parameter
    is set,
    provider() returns a tuple of 2 elements: the usual provider
    symbol (which,
    when called, invokes init) and a raw constructor (which bypasses
    init).
  - Tests that fail to create or complete their
    `TestAttemptContinuation` by
    throwing an `ExecException` will report an `INCOMPLETE` status.
    Previously, Bazel
    would fail to report any status for the test attempt.
  - Fixed an issue where Bazel could erroneously report a test passes
    in coverage mode without actually running the test.
  - Include more information about configurations in cquery proto
    formatted output. This deprecates the configuration field of
    AnalysisProtosV2.ConfiguredTarget, and adds a new field,
    configuration_id, to
    be used instead.
  - experimental cc_library.implementation_deps inverted to
    interface_deps
  - In aquery and cquery proto output, indicate if a configuration is
    a
    tool or non-tool configuration.
  - Include complete configurations in cquery proto output.
  - experimental cc_library.implementation_deps inverted to
    interface_deps
  - Make protocOpts() publicly accessible.
  - Add some documentation about how configuration information is
    conveyed in cquery proto output.
  - Introduces experimental static library linking API under
    apple_common.link_multi_arch_static_library
  - Further deprecation and removal of pkg_tar. Stop supporting
    legacy use of 'files' attribute, where it could be a list of
    labels instead of a map of paths to labels.
  - Removed --incompatible_no_build_defs_pkg flag. It never fulfilled
    its purpose because --all_incompatible_changes would never set
    it. The last rule it gated (pkg_tar) is scheduled to be removed
    in Bazel 6.x.
  - Add coverage configuration fragment, used to expose
    output_generator label.
  - Bazel now no longer includes system headers on macOS in coverage
    reports (bazelbuild#14969).
  - android_sdk_repository read $ANDROID_SDK_ROOT in addition to
    $ANDROID_HOME.
  - The default dexer is now d8. dx can be optionally enabled using:
      --define=android_dexmerger_tool=dx_dexmerger \
      --define=android_incremental_dexing_tool=dx_dexbuilder \
      --define=android_standalone_dexing_tool=dx_compat_dx \
      --use_workers_with_dexbuilder
  - Packaging support for deploy JAR embedded JDK files (hermetic
    Java).
  - Don't stamp cc_common.link actions for tool dependencies.
  - Starlark test rules can use the new inherited_environment
    parameter of testing.TestEnvironment to specify environment
    variables
    whose values should be inherited from the shell environment.
  - Enable merging permissions during Android manifest merging with
    the --merge_android_manifest_permissions flag.
  - Allow specialization to work with constraint_values.
  - Bazel uses the D8 jar from Maven instead of the SDK.
  - Make ijar / java_import preserve classes with `@kotlin.Metadata`
    annotations
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather than always linking statically when Windows is
    the _host_).
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather than always linking statically when Windows is
    the _host_).
  - Add devtools/build/lib/worker:work_request_handlers to the remote
    android tools release package. This will be transitively packaged
    into all_android_tools.
  - Bazel uses the D8 jar from Maven instead of the SDK.
  - android_sdk_repository read $ANDROID_SDK_ROOT in addition to
    $ANDROID_HOME.
  - Advance android_tools_pkg version to 0.24.0.
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather
    than always linking statically when Windows is the _host_).
  - Bazel uses the D8 jar from Maven instead of the SDK.
  - "blaze config" now only reports info from the last build. To
    compare configurations across multiple builds, redirect "blaze
    config" output to a file and run your favorite diff tool.
  - The --incompatible_override_toolchain_transition flag is now
    always set, and will be removed in the future. Thus,
    --noincompatible_override_toolchain_transition has no effect, and
    the value of the incompatible_use_toolchain_transition parameter
    in aspect() and rule() builtins is ignored.
  - Switch cc_test implementation to Starlark. Note: cc_test will now
    link statically when _targeting_ Windows regardless of host
    platform (rather
    than always linking statically when Windows is the _host_).
  - Toolchain types may now be optional, in addition to mandatory.
    See https://bazel.build/docs/toolchains#optional-toolchains for
    further details.
  - Add six to deps of has_services=1 py_proto_librarys.
  - pkg_tar(symlinks) has been removed. Users needing that feature
    should
    migrate to @rules_pkg.
  - Aspects can now define and use exec groups using the same API as
    rules.
  - Removed the obsolete --incompatible_applicable_licenses flag. The
    feature is permanently enabled.
  - embedded_tools packages R8 desugarer again
  - Bazel now selects sh path based on execution platform instead of
    host platform, making it possible to execute sh actions in
    multiplatform builds. --shell_executable now only applies to
    actions configured for host.
  - labels in genquery.scope are no longer configured.
  - When Bzlmod is enabled, all Bzlmod-generated repos will have an
    extra '@' prepended to their names. This effectively enables the
    canonical label literal syntax for Bzlmod-generated repos
    (`@@canonicalRepoName//pkg:target`; see
    https://docs.google.com/document/d/1N81qfCa8oskCk5LqTW-LNthy6EBrDo
    t7bdUsjz6JFC4/edit?usp=sharing).
  - Exposed `CcSharedLibraryInfo` to Starlark builtins.
  - Enable --use_top_level_targets_for_symlinks by default.
  - Singlejar accepts runtime Created-By field
  - --noincompatible_disable_managed_directories, and with that,
    workspace(managed_directories=) is not supported anymore.
  - Bazel supports D8 desugaring, albeit without persistent workers
  - Remove mtime options from pkg_tar. Users should migrate to
    @rules_pkg.
  - Test for experimental multiplexed persistent resource processor.
  - Added new register_{execution_platforms,toolchains} directives to
    the MODULE.bazel file, to replace the
    {execution_platforms,toolchains}_to_register attributes on the
    module() directive.
  - The legacy pkg_tar no longer supports the ability to untar and
    repackage an input tar file (`deps` attribute). Users needed that
    capability must switch to github.com/bazelbuild/rules_pkg.
  - `cquery`'s new output mode
    [`--output=files`](https://bazel.build/docs/cquery#files-output)
    lists the output files of the targets matching the query. It
    takes the current value of `--output_groups` into account.
  - Change singlejar metadata to report Created-By Bazel
  - Add support for fetching RPC credentials from credential helper.
  - Revert interface_deps back to implementation_deps after problem
    reported in. Use `buildozer 'rename deps implementation_deps'
    //...:%cc_library; buildozer 'rename interface_deps deps'
    //...:%cc_library`
  - Fix for desugaring failure on Bazel+Android+Windows build
    scenario.
  - D8 is the default desugarer
  - Migrate main_dex_list_creator to D8 (DX deprecation)
  - --experimental_enable_bzlmod has been renamed --enable_bzlmod,
    and still defaults to false.
  - selects() no longer produce irrelevant duplicate label checks
  - Adds a dexer output cache to CompatDexBuilder to improve build
    speed.
  - Improved error messages when analyzing inline bzl code
  - Improved error messages when analyzing inline bzl code
  - The `@bazel_tools//tools/cpp:compiler` flag now has the value
    `gcc` if the configured compiler is detected to be gcc rather
    than the generic value `compiler`. A branch for `gcc` may have to
    be added to `select` statements that do not have a default case
    that handles gcc appropriately.
  - The `get_child` method of `path` now accepts an arbitrary
    number of relative path strings as positional arguments.
  - SourceManifestAction supports `Action.content`
  - Add --incompatible_build_transitive_python_runfiles alias. See
    bazelbuild#16303
  - The @bazel_tools//tools/cpp:compiler flag now has the value
    `clang` for the auto-configured Xcode toolchain rather than the
    generic value compiler. A branch for `clang` may have to be added
    to select statements that do not have a default case that handles
    this toolchain appropriately.
  - added additional debug message to warn of skipped toolchains
    during resolution
  - The deprecated --remote_allow_symlink_upload flag has been
    removed. Symlinks in local action outputs are always permitted,
    even with remote caching. Whether they're uploaded as symlinks or
    as the files/directories they point to is still determined by the
    --incompatible_remote_symlinks flag.
  - Added `struct`, `json`, `proto`, and `depset` to the starlark
    environment of Bazel's cquery (--output=starlark) command
  - Added three `package_group`-related flags:
    `--incompatible_package_group_includes_double_slash` (bazelbuild#16391),
    `--incompatible_package_group_has_public_syntax` (bazelbuild#16355), and
    `--incompatible_fix_package_group_reporoot_syntax` (bazelbuild#16323). With
    these flags, `package_group` can now easily specify "all
    packages", "no packages", and "all packages in the current repo".
  - Record hermetic packaged JDK modules file size in deploy JAR
    manifest 'JDK-Lib-Modules-Size' attribute.
  - .bzl files may now set a visibility to guard what other .bzl and
    BUILD files may load them. See [...] for more information.
  - Deletes the --extra_proguard_specs Blaze flag
  - The new path variable `$(rlocationpath ...)` and its plural form
    `$(rlocationpaths ...)` can be used to expand labels to the paths
    accepted by the `Rlocation` function of runfiles libraries. This
    is the preferred way to access data dependencies at runtime and
    works on all platforms, even when runfiles are not enabled (e.g.,
    on Windows by default).
  - Starlark `print()` statements are now emitted iff the line of
    code is executed. They are no longer replayed on subsequent
    invocations unless the Starlark code is re-executed.
    Additionally, multiple identical `print()` statements (same
    string from the same line of code, e.g. from a loop) are all
    emitted and no longer deduplicated.
  - Fixes a bug where some compilation flags would not be applied to
    a cc_test
  - removed outdated ctx.host_fragments
  - removed outdated ctx.host_configuration
  - Now that the host configuration is finished, `genrule` should
    prefer the use of `tools` and stop using `exec_tools`.
  - Added a `native.package_relative_label()` function, which
    converts a label string to a Label object in the context of the
    calling package, in contrast to `Label()`, which does so in the
    context of the current .bzl file. Both functions now also accept
    relative labels such as `:foo`, and are idempotent.
  - Update Android manifest merger to v30.1.3, and also drop support
    for legacy (pre-D8) desugaring.
  - Adds coverage metric support to android_local_test
  - Correctly encode double value positive infinity as "inf" instead
    of "+inf" for textprotos.
  - Add --use_target_platform_for_tests which uses the target
    platform for executing tests instead of the execution platform.
  - Custom C++ rules on Windows calling
    cc_common.create_linking_context_from_compilation_outputs should
    review whether each target of the rule type should produce a
    dynamic library since a condition which blocked their creation
    has been moved to the rules from behind the API.
  - Add flag `--experimental_remote_cache_ttl` and set the default
    value to 3 hours.
  - making --incompatible_use_platforms_repo_for_constraints do
    nothing. Using constraints from @bazel_tools//platforms with or
    without the flag will throw error with message "Constraints from
    @bazel_tools//platforms have been removed. Please use constraints
    from @platforms repository embedded in Bazel, or preferably
    declare dependency on https://github.com/bazelbuild/platforms"
  - Fixed an issue where WORKSPACE and WORKSPACE-loaded .bzl files
    couldn't see the Bzlmod root module's mappings when Bzlmod is
    enabled.
  - Subsequent settings of --extra_execution_platforms now override
    previous settings, instead of adding them to a list. If you
    currently set --extra_execution_platforms more than once, please
    migrate by passing a list of values to
    --extra_execution_platforms instead so that earlier values aren't
    overwritten.
  - @bazel_tools//config:common_settings.bzl has been removed.
    Use @bazel_skylib//rules:common_settings.bzl instead.
  - cc_shared_library is no longer experimental, see
    bazelbuild#16709 for details
  - The flag `--distinct_host_configuration` is removed. It has been
    a no-op since Bazel 6.0.0.
  - Added `native.module_name()` and `native.module_version()` to
    allow BUILD macro authors to acquire information about which
    Bazel module the current repo is associated with.
  - Add `--skip_incompatible_explicit_targets` option
  - Remove 'darwin' as a CPU value, use 'darwin_x86_64' instead
  - cc_test can now be configured by using a native.toolchain().
  - `@foo` labels can now be used on the command line as the
    top-level target (that is, `bazel build @foo` now works).
    Double-dot syntax is now forbidden (`bazel build ../foo` will no
    longer work).
  - The location of rules that explicitly specify `generator_name`
    and/or `generator_function` attributes (typically because they
    are incidentally copied from `native.existing_rule()`) is now the
    top-level call in the `BUILD` file, which is consistent with
    rules that do not explicitly specify these attributes.
  - Warnings (most notably those associated with the `deprecation`
    rule attribute) are no longer replayed on subsequent invocations
    unless the target in question is re-analyzed. Warnings are purely
    informational, so this change has no bearing on the correctness
    of the build. Downstream tests that break due to this change
    should update their expectations.
  - `--experimental_remote_build_event_upload` has been renamed to
    `--remote_build_event_upload`
  - [Breaking change] platform, constraint_setting, and
    constraint_value can no longer take an applicable_licenses value.
    Remediation is to remove the attribute and rely on the package
    level default.
  - `--experimental_action_cache_store_output_metadata` has been
    renamed to `--action_cache_store_output_metadata`
  - Changed the default value for `--remote_build_event_upload` to
    `minimal`.
  - `--experimental_remote_cache_compression` has been renamed to
    `--remote_cache_compression`
  - The REPO.bazel and MODULE.bazel files are now also considered
    workspace boundary markers.
