This is a tracking issue for offering a migration solution for
--incompatible_string_is_not_iterable

This flag would disable iterating over skylark strings. (note indexing and len are still allowed)

What is missing for migration: migration docs, length of migration window. After these are done, please add "migration-ready" label.

Migration:

Either use string.elems():

for i in "abc".elems():
  ...

or use an index:

for i in range(len(s)):
  char = s[i]
  ...

Release 0.22.0 (2019-01-28)
2f82b33 
Baseline: deb028e

Cherry picks:

   + a3a5975:
     Fix a race condition in remote cache
   + b8d0e1b:
     Use a new GitHub token and KMS key for the release process.
   + 3759e38:
     remote: fix unexpected IO error (not a directory)
   + 4473bb1:
     Fix a race condition in Bazel's Windows process management.
   + 9137fb9:
     undo flag flip of --incompatible_strict_action_env
   + 12ab12e:
     Revert "Enabling Bazel to generate input symlinks as defined by
     RE AP?
   + 6345c74:
     Automated rollback of commit
     30536ba.

New features:

  - Add inputs filtering for aquery
  - https://docs.bazel.build now supports versioned
    documentation. Use the selector at the top of the navigation bar
    to
    switch between documentation for different Bazel releases.
  - build_tar.py in tools/build_defs/pkg now supports a json manifest
    that can be used to add paths that have symbols that can't be
    specified via the command line

Important changes:

  - Added `--incompatible_dont_emit_static_libgcc`
    (#6825)
    Added `--incompatible_linkopts_in_user_link_flags`
    (#6826)
  - mobile-install now works with aapt2. Try it out with `bazel
    mobile-install --android_aapt=aapt2 //my:target`
  - Fixed a mobile-install v1 bug when deploying to Android 9 Pie
    devices. #6814
  - Add a new option --xbinary_fdo to pass xbinary profile.
  - --runs_per_test: place in TESTING documentation category.
  - Adds a clarifying message to test case summary output when all
    test cases pass but the target fails.
  - Fixed mobile-install v1 error when installing an app with native
    libraries onto an Android 9 (Pie) device. See
    bazelbuild/examples#77
  - Fixed issue where error messages from Android manifest merging
    actions were not propagated fully.
  - Add outputs and mnemonic filtering to aquery
  - New incompatible change flag for defaulting to aapt2 in Android
    builds: `--incompatible_use_aapt2_by_default`. To build with
    aapt2 today, pass the flag
    `--incompatible_use_aapt2_by_default=true` or
    `--android_aapt=aapt2`, or set the `aapt_version`  to `aapt2` on
    your `android_binary` or `android_local_test` target.
  - set projectId in all PublishBuildToolEventStreamRequest
  - Flip flag --incompatible_string_is_not_iterable
    (#5830)
  - cc_toolchain.(static|dynamic)_runtime_libs attributes are now
    optional
  - Added --incompatible_disable_runtimes_filegroups
    (#6942).
  - objc_bundle has been removed. Please migrate to rules_apple's
    [apple_bundle_import](https://github.com/bazelbuild/rules_apple/bl
    ob/master/doc/rules-resources.md#apple_bundle_import).
  - The apple_stub_binary rule has been deleted.
  - Incompatible flag `--incompatible_dont_emit_static_libgcc` has
    been flipped (#6825)
  - Incompatible flag `--incompatible_linkopts_in_user_link_flags`
    has been flipped (#6826)
  - Open source aquery & cquery query2 tests
  - Fixed a mobile-install bug where `arm64-v8a` libraries were not
    deployed correctly on `arm64` devices. This was done by enabling
    incremental native lib deployment by default. A previously
    undocumented `--android_incremental_native_libs` flag is removed,
    and is now the regular behavior. See
    #2239
  - Incompatible flag `--incompatible_linkopts_in_user_link_flags`
    has been flipped (#6826)
  - Incompatible flag `--incompatible_dont_emit_static_libgcc` has
    been flipped (#6825)
  - Added --incompatible_disable_legacy_crosstool_fields. See the
    migration notes at
    #6861.
  - In the Query HowTo, recommend ":*" instead of ":all". "all" might
    be the name of a target.
  - The default value for --incompatible_strict_action_env has been
    flipped to 'false' again, as we discovered breakages for local
    execution users. We'll need some more time to figure out the best
    way to make this work for local and remote execution. Follow
    #7026 for more details.

This release contains contributions from many people at Google, as well as Benjamin Peterson, Dave Lee, George Gensure, Gert van Dijk, Gustavo Storti Salibi, Keith Smiley, Loo Rong Jie, Lukasz Tekieli, Mikhail Mazurskiy, Thi, Travis Cline, Vladimir Chebotarev, Yannic.
