1.11.0

CHANGES:

• Don't select all local implementations in dune utop. Instead, let the
  default implementation selection do its job. (#2327, fixes #2323, @TheLortex,
  review by @rgrinberg)

• Check that selected implementations (either by variants or default
  implementations) are indeed implementations. (#2328, @TheLortex, review by
  @rgrinberg)

• Don't reserve the Ppx toplevel module name for ppx rewriters (#2242, @diml)

• Redesign of the library variant feature according to the #2134 proposal. The
  set of variants is now computed when the virtual library is installed.
  Introducing a new external_variant stanza. (#2169, fixes #2134, @TheLortex,
  review by @diml)

• Add proper line directives when copying .cc and .cxx sources (#2275,
  @rgrinberg)

• Fix error message for missing C++ sources. The .cc extension was always
  ignored before. (#2275, @rgrinberg)

• Add $ dune init project subcommand to create project boilerplate according
  to a common template. (#2185, fixes #159, @shonfeder)

• Allow to run inline tests in javascript with nodejs (#2266, @hhugo)

• Build ppx.exe as compiling host binary. (#2286, fixes #2252, @toots, review
  by @rgrinberg and @diml)

• Add a cinaps extension and stanza for better integration with the
  cinaps tool tool (#2269,
  @diml)

• Allow to embed build info in executables such as version and list
  and version of statically linked libraries (#2224, @diml)

• Set version in META and dune-package files to the one read from
  the vcs when no other version is available (#2224, @diml)

• Add a variable %{target} to be used in situations where the context
  requires at most one word, so %{targets} can be confusing; stdout
  redirections and "-o" arguments of various tools are the main use
  case; also, introduce a separate field target that must be used
  instead of targets in those situations. (#2341, @aalekseyev)

• Fix dependency graph of wrapped_compat modules. Previously, the dependency on
  the user written entry module was omitted. (#2305, @rgrinberg)

• Allow to promote executables built with an executable stanza
  (#2379, @diml)

• When instantiating an implementation with a variant, make sure it matches
  virtual library's list of known implementations. (#2361, fixes #2322,
  @TheLortex, review by @rgrinberg)

• Add a variable %{ignoring_promoted_rules} that is true when
  --ingore-promoted-rules is passed on the command line and false
  otherwise (#2382, @diml)

• Fix a bug in future_syntax where the characters @ and & were
  not distinguished in the names of binding operators (let@ was the
  same as let&) (#2376, @aalekseyev, @diml)

• Workspaces with non unique project names are now supported. (#2377, fix #2325,
  @rgrinberg)

• Improve opam generation to include the dune dependncies with the minimum
  constraint set based on the dune language version specified in the
  dune-project file. (2383, @avsm)

• The order of fields in the generated opam file now follows order preferred in
  opam-lib. (@avsm, #2380)

• Fix coloring of error messages from the compiler (@diml, #2384)

• Add warning 66 to default set of warnings starting for dune projects with
  language verison >= 1.11 (@rgrinberg, @diml, fixes #2299)

• Add (dialect ...) stanza
  (@nojb, #2404)

• Add a --context argument to dune install/uninstall (@diml, #2412)

• Do not warn about merlin files pre 1.9. This warning can only be disabled in
  1.9 (#2421, fixes #2399, @emillon)

• Add a new inline_tests field in the env stanza to control inline_tests
  framework with a variable (#2313, @mlasson, original idea by @diml, review
  by @rgrinberg).

• New binary kind js for executables in order to explicitly enable Javascript
  targets, and a switch (explicit_js_mode) to require this mode in order to
  declare JS targets corresponding to executables. (#1941, @nojb)

1.10.0

CHANGES:

• Restricted the set of variables available for expansion in the destination
  filename of install stanza to simplify implementation and avoid dependency
  cycles. (#2073, @aalekseyev, @diml)

• [menhir] call menhir from context root build_dir (#2067, @ejgallego,
  review by @diml, @rgrinberg)

• [coq] Add coq.pp stanza to help with pre-processing of grammar
  files (#2054, @ejgallego, review by @rgrinberg)

• Add a new more generic form for the promote mode: (promote (until-clean) (into <dir>)) (#2068, @diml)

• Allow to promote only a subset of the targets via (promote (only <pred>)). For instance: (promote (only *.mli)) (#2068, @diml)

• Improve the behavior when a strict subset of the targets of a rule is already
  in the source tree for projects using the dune language < 1.10 (#2068, fixes
  #2061, @diml)

• With lang dune >= 1.10, rules in standard mode are no longer allowed to
  produce targets that are present in the source tree. This has been a warning
  for long enough (#2068, @diml)

• Allow %{...} variables in pps flags (#2076, @mlasson review by @diml and
  @aalekseyev).

• Add a 'cookies' option to ppx_rewriter/deriver flags in library stanzas. This
  allow to specify cookie requests from variables expanded at each invocation of
  the preprocessor. (#2106, @mlasson @diml)

• Add more opam metadata and use it to generate .opam files. In particular, a
  package field has been added to specify package specific information.
  (#2017, #2091, @avsm, @jonludlam, @rgrinberg)

• Clean up the special support for findlib.dynload. Before, Dune would simply
  match on the library name. Now, we only match on the findlib package name when
  the library doesn't come from Dune. Someone writing a library called
  findlib.dynload with Dune would have to add (special_builtin_support findlib_dynload) to trigger the special behavior. (#2115, @diml)

• Install the future_syntax preprocessor as ocaml-syntax-shims.exe (#2125,
  @rgrinberg)

• Hide full command on errors and warnings in development and show them in CI.
  (detected using the CI environment variable). Commands for which the
  invocation might be omitted must output an error prefixed with File . Add an
  --always-show-command-line option to disable this behavior and always show
  the full command. (#2120, fixes #1733, @rgrinberg)

• In dune-workspace files, add the ability to choose the host context and to
  create duplicates of the default context with different settings. (#2098,
  @TheLortex, review by @diml, @rgrinberg and @aalekseyev)

• Add support for hg in dune subst (#2135, @diml)

• Don't build documentation for implementations of virtual libraries (#2141,
  fixes #2138, @jonludlam)

• Fix generation of the -pp flag in .merlin (#2142, @rgrinberg)

• Make dune subst add a (version ...) field to the dune-project
  file (#2148, @diml)

• Add the %{os_type} variable, which is a short-hand for
  %{ocaml-config:os_type} (#1764, @diml)

• Allow enabled_if fields in library stanzas, restricted to the
  %{os_type}, %{model}, %{architecture}, %{system} variables (#1764,
  #2164 @diml, @rgrinberg)

• Fix chdir on external and source paths. Dune will also fail gracefully if
  the external or source path does not exist (#2165, fixes #2158, @rgrinberg)

• Support the .cc extension fro C++ sources (#2195, fixes #83, @rgrinberg)

• Run ocamlformat relative to the context root. This improves the locations of
  errors. (#2196, fixes #1370, @rgrinberg)

• Fix detection of README, LICENSE, CHANGE, and HISTORY files. These
  would be undetected whenever the project was nested in another workspace.
  (#2194, @rgrinberg)

• Fix generation of .merlin whenever there's more than one stanza with the
  same ppx preprocessing specification (#2209 ,fixes #2206, @rgrinberg)

• Fix generation of .merlin in the presence of the copy_files stanza and
  preprocessing specifications of other stanazs. (#2211, fixes #2206,
  @rgrinberg)

• Run refmt from the context's root directory. This improves error messages in
  case of syntax errors. (#2223, @rgrinberg)

• In .merlin files, don't pass -dump-ast to the future_syntax preprocessor.
  Merlin doesn't seem to like it when binary AST is generated by a -pp
  preprocessor. (#2236, @aalekseyev)

• dune install will verify that all files mentioned in all .install files
  exist before trying to install anything. This prevents partial installation of
  packages (#2230, @rgrinberg)

1.9.3

CHANGES:

• Fix .install files not being generated (#2124, fixes #2123, @rgrinberg)

1.9.2

CHANGES:

• Put back library variants in development mode. We discovered a
  serious unexpected issue and we might need to adjust the design of
  this feature before we are ready to commit to a final version. Users
  will need to write (using library_variants 0.1) in their
  dune-project file if they want to use it before the design is
  finalized. (#2116, @diml)

• Forbid to attach a variant to a library that implements a virtual
  library outside the current project (#2104, @rgrinberg)

• Fix a bug where dune install would install man pages to incorrect
  paths when compared to opam-installer. For example dune now
  installs (foo.1 as man1/foo.1) correctly and previously that was
  installed to man1/man1/foo.1. (#2105, @aalekseyev)

• Do not fail when a findlib directory doesn't exist (#2101, fix #2099, @diml)

• [coq] Rename (coqlib ...) to (coq.theory ...), support for
  coqlib will be dropped in the 1.0 version of the Coq language
  (#2055, @ejgallego)

• Fix crash when calculating library dependency closure (#2090, fixes #2085,
  @rgrinberg)

1.9.1

CHANGES:

• Fix invocation of odoc to add previously missing include paths, impacting
  mld files that are not in directories containing libraries (#2016, fixes
  #2007, @jonludlam)

1.9.0

CHANGES:

• Warn when generated .merlin does not reflect the preprocessing
  specification. This occurs when multiple stanzas in the same directory use
  different preprocessing specifications. This warning can now be disabled with
  allow_approx_merlin (#1947, fix #1946, @rgrinberg)

• Watch mode: display "Success" in green and "Had errors" in red (#1956,
  @emillon)

• Fix glob dependencies on installed directories (#1965, @rgrinberg)

• Add support for library variants and default implementations. (#1900,
  @TheLortex)

• Add experimental $ dune init command. This command is used to create or
  update project boilerplate. (#1448, fixes #159, @shonfeder)

• Experimental Coq support (fix #1466, @ejgallego)

• Install .cmi files of private modules in a .private directory (#1983, fix
  #1973 @rgrinberg)

• Fix dune subst attempting to substitute on directories. (#2000, fix #1997,
  @rgrinberg)

• Do not list private modules in the generated index. (#2009, fix #2008,
  @rgrinberg)

• Warn instead of failing if an opam file fails to parse. This opam file can
  still be used to define scope. (#2023, @rgrinberg)

• Do not crash if unable to read a directory when traversing to find root
  (#2024, @rgrinberg)

• Do not exit dune if some source directories are unreadable. Instead, warn the
  user that such directories need to be ignored (#2004, fix #310, @rgrinberg)

• Fix nested (binaries ..) fields in the env stanza. Previously, parent
  binaries fields would be ignored, but instead they should be combined.
  (#2029, @rgrinberg)

• Allow "." in c_names and cxx_names (#2036, fix #2033, @rgrinberg)

• Format rules: if a dune file uses OCaml syntax, do not format it.
  (#2014, fix #2012, @emillon)

1.8.2

CHANGES:

• Fix auto-generated index.mld. Use correct headings for the listing. (#1925,
  @rgrinberg, @aantron)

1.8.1

CHANGES:

• Correctly write dune-package when version is empty string (#1919, fix #1918,
  @rgrinberg)

1.8.0

CHANGES:

• Clean up watch mode polling loop: improves signal handling and error handling
  during polling (#1912, fix #1907, fix #1671, @aalekseyev)

• Change status messages during polling to be one-line, so that the messages are
  correctly erased by ^K. (#1912, @aalekseyev)

• Add support for .cxx extension for C++ stubs (#1831, @rgrinberg)

• Add DUNE_WORKSPACE variable. This variable is equivalent to setting
  --workspace in the command line. (#1711, fix #1503, @rgrinberg)

• Add c_flags and cxx_flags to env profile settings (#1700 and #1800,
  @gretay-js)

• Format dune printenv output (#1867, fix #1862, @emillon)

• Add the (promote-into <dir>) and `(promote-until-clean-into

  )` modes for `(rule ...)` stanzas, so that files can be promoted in another directory than the current one. For instance, this is used in merlin to promote menhir generated files in a directory that depends on the version of the compiler (#1890, @diml)

• Improve error message when dune subst fails (#1898, fix #1897, @rgrinberg)

• Add more GC counters to catapult traces (fix908, @rgrinberg)

• Add a preprocessor shim for the let+ syntax of OCaml 4.08 (#1899,
  implements #1891, @diml)

• Fix generation of .merlin files on Windows. \ characters needed
  to be escaped (#1869, @mlasson)

• Fix 0 error code when $ dune format-dune-file fails. (#1915, fix #1914,
  @rgrinberg)

• Configurator: deprecated query_expr and introduced query_expr_err which is
  the same but with a better error in case it fails. (#1886, @ejgallego)

• Make sure (menhir (mode promote) ...) stanzas are ignored when
  using --ignore-promoted-rules or -p (#1917, @diml)

1.7.3

CHANGES:

• Fix interpretation of META files containing archives with / in
  the filename. For instance, this was causing llvm to be unusable
  with dune (#1889, fix #1885, @diml)

• Make errors about menhir stanzas be located (#1881, fix #1876,
  @diml)
