Release 3.19.1
CHANGES:
- Revert changes in `dune exec` behaviour introduced in 3.19.0. (#11879, fixes
  #11870, #11867 and #11881, @Alizter)

Release 3.19.0
CHANGES:
- Fixed a bug that was causing cram tests attached to multiple aliases to be run multiple
  times. (#11547, @Alizter)

  flag would result in pkgconf not finding libraries in some contexts. (#11619, @MisterDA)
- Fix: Evaluate `enabled_if` when computing the stubs for stanzas such as
  `foreign_library` (#11707, @Alizter, @rgrinberg)
- Fix $ dune describe pp for libraries in the presence of `(include_subdirs
  unqualified)` (#11729, fixes #10999, @rgrinberg)
- Fix `$ dune subst` in sub directories of a git repository (#11760, fixes
  #11045, @Richard-Degenne)
- Fix a crash involving `Path.drop_prefix` when using Melange on Windows
  (#11767, @nojb)
- Added detection and warning for common typos in package dependency
  constraints (#11600, fixes #11575, @kemsguy7)
- Added `(extra_objects)` field to `(foreign_library)` stanza with `(:include)` support.
  (#11683, @Alizter)
- Allow build RPC messages to be handled by dune's RPC server in eager watch
  mode (#11622, @gridbugs)
- Allow concurrent build with RPC server (#11712, @gridbugs)

Release 3.18.2
CHANGES:
- fix compatibility with `ocaml.5.4.0` by avoiding shadowing sigwinch (@nojb,
  #11639)

Release 3.18.1
CHANGES:
- fix: pass pkg-config (extra) args in all pkgconfig invocations. A missing
  `--personality` flag would result in pkgconf not finding libraries in some
  contexts. (#11619, @MisterDA)

Release 3.18.0
CHANGES:
- Support HaikuOS: don't call `execve` since it's not allowed if other pthreads
  have been created. The fact that Haiku can't call `execve` from other threads
  than the principal thread of a process (a team in haiku jargon), is a
  discrepancy to POSIX and hence there is a [bug about
  it](https://dev.haiku-os.org/ticket/18665). (@Sylvain78, #10953)
- Fix flag ordering in generated Merlin configurations (#11503, @voodoos, fixes
  ocaml/merlin#1900, reported by @vouillon)
- Add `(format-dune-file <src> <dst>)` action. It provides a replacement to
  `dune format-dune-file` command.  (#11166, @nojb)
- Allow the `--prefix` flag when configuring dune with `ocaml configure.ml`.
  This allows to set the prefix just like `$ dune install --prefix`. (#11172,
  @rgrinberg)
- Allow arguments starting with `+` in preprocessing definitions (starting with
  `(lang dune 3.18)`). (@amonteiro, #11234)
- Support for opam `(maintenance_intent ...)` in dune-project (#11274, @art-w)
- Validate opam `maintenance_intent` (#11308, @art-w)
- Support `not` in package dependencies constraints (#11404, @art-w, reported
  by @hannesm)
- Warn when failing to discover root due to reads failing. The previous
  behavior was to abort. (@KoviRobi, #11173)
- Use shorter path for inline-tests artifacts. (@hhugo, #11307)
- Allow dash in `dune init` project name (#11402, @art-w, reported by @saroupille)
- On Windows, under heavy load, file delete operations can sometimes fail due to
  AV programs, etc. Guard against it by retrying the operation up to 30x with a
  1s waiting gap (#11437, fixes #11425, @MSoegtropIMC)
- Cache: we now only store the executable permission bit for files (#11541,
  fixes #11533, @ElectreAAS)
- Display negative error codes on Windows in hex which is the more customary
  way to display `NTSTATUS` codes (#11504, @MisterDA)

Release 3.17.2
CHANGES:
- Fix a crash in the Melange rules that would prevent compiling public library
implementations of virtual libraries. (@amonteiro, #11248)
- Pass `melange.emit`'s `compile_flags` to the JS emission phase. (@amonteiro,

Release 3.17.1
CHANGES:
- When a library declares `(no_dynlink)`, then the `.cmxs` file for it
  is no longer built. (#11176, @nojb)
- Fix bug that could result in corrupted file copies by Dune, for example when
  using the `copy_files#` stanza or the `copy#` action. (@nojb, #11194, fixes
  #11193)
- Remove useless error message when running `$ dune subst` in empty projects.
  (@rgrinberg, #11204, fixes #11200)

Release 3.17.0
CHANGES:
- Show the context name for errors happening in non-default contexts.
  (#10414, fixes #10378, @jchavarri)
- Correctly declare dependencies of indexes so that they are rebuilt when
  needed. (#10623, @voodoos)
- Don't depend on coq-stdlib being installed when expanding variables
  of the `coq.version` family (#10631, fixes #10629, @gares)
- Error out if no files are found when using `copy_files`. (#10649, @jchavarri)
- Re_export dune-section private library in the dune-site library stanza,
  in order to avoid failure when generating and building sites modules
  with implicit_transitive_deps = false. (#10650, fixes #9661, @MA0100)
- Expect test fixes: support multiple modes and fix dependencies when there is
  a custom runner (#10671, @vouillon)
- In a `(library)` stanza with `(extra_objects)` and `(foreign_stubs)`, avoid
  double linking the extra object files in the final executable.
  (#10783, fixes #10785, @nojb)
- Map `(re_export)` library dependencies to the `exports` field in `META` files,
  and vice-versa. This field was proposed in to
  https://discuss.ocaml.org/t/proposal-a-new-exports-field-in-findlib-meta-files/13947.
  The field is included in Dune-generated `META` files only when the Dune lang
  version is >= 3.17.
  (#10831, fixes #10830, @nojb)
- Fix staged pps preprocessors on Windows (which were not working at all
  previously) (#10869, fixes #10867, @nojb)
- Fix `dune describe` when an executable is disabled with `enabled_if`.
  (#10881, fixes #10779, @moyodiallo)
- Fix an issue where C stubs would be rebuilt whenever the stderr of Dune was
  redirected. (#10883, fixes #10882, @nojb)
- Fix the URL opened by the command `dune ocaml doc`. (#10897, @gridbugs)
- Fix the file referred to in the error/warning message displayed due to the
  dune configuration version not supporting a particular configuration
  stanza in use. (#10923, @H-ANSEN)
- Fix `enabled_if` when it uses `env` variable. (#10936, fixes #10905, @moyodiallo)
- Fix exec -w for relative paths with --root argument (#10982, @gridbugs)
- Do not ignore the `(locks ..)` field in the `test` and `tests` stanza
  (#11081, @rgrinberg)
- Tolerate files without extension when generating merlin rules.
  (#11128, @anmonteiro)
- Make Merlin/OCaml-LSP aware of "hidden" dependencies used by
  `(implicit_transitive_deps false)` via the `-H` compiler flag. (#10535, @voodoos)
- Add support for the -H flag (introduced in OCaml compiler 5.2) in dune
  (requires lang versions 3.17). This adaptation gives
  the correct semantics for `(implicit_transitive_deps false)`.
  (#10644, fixes #9333, ocsigen/tyxml#274, #2733, #4963, @MA0100)
- Add support for specifying Gitlab organization repositories in `source`
  stanzas (#10766, fixes #6723, @H-ANSEN)
- New option to control jsoo sourcemap generation in env and executable stanza
  (#10777, fixes #10673, @hhugo)
- One can now control jsoo compilation_mode inside an executable stanza
  (#10777, fixes #10673, @hhugo)
- Add support for specifying default values of the `authors`, `maintainers`, and
  `license` stanzas of the `dune-project` file via the dune config file. Default
  values are set using the `(project_defaults)` stanza (#10835, @H-ANSEN)
- Add names to source tree events in performance traces (#10884, @jchavarri)
- Add `codeberg` as an option for defining project sources in dune-project
  files. For example, `(source (codeberg user/repo))`. (#10904, @nlordell)
- `dune runtest` can now run individual tests with `dune runtest mytest.t`
  (#11041, @Alizter).
- Wasm_of_ocaml support (#11093, @vouillon)
- Add a `coqdep_flags` field to the `coq` field of the `env` stanza, and to the `coq.theory` stanza, allowing to configure `coqdep` flags.
  (#11094, @rlepigre)
- Remove all remnants of the experimental `patch-back-source-tree`. (#10771,
  @rgrinberg)
- Change the preset value for author and maintainer fields in the
  `dune-project` file to encourage including emails. (#10848, @punchagan)
- Tweak the preset value for tags in the `dune-project` file to hint at topics
  not having a special meaning. (#10849, @punchagan)
- Change some colors to improve readability in light-mode terminals
  (#10890, @gridbugs)
- Forward the linkall flag to jsoo in whole program compilation as well (#10935, @hhugo)
- Configurator uses `pkgconf` as pkg-config implementation when available
  and forwards it the `target` of `ocamlc -config`. (#10937, @pirbo)
- Enable Dune cache by default. Add a new Dune cache setting
  `enabled-except-user-rules`, which enables the Dune cache, but excludes
  user-written rules from it. This is a conservative choice that can avoid
  breaking rules whose dependencies are not correctly specified. This is the
  current default. (#10944, #10710, @nojb, @ElectreAAS)
- Do not add `dune` dependency in `dune-project` when creating projects with
  `dune init proj`. The Dune dependency is implicitely added when generating
  opam files (#11129, @Leonidas-from-XIV)
