3.16.0~alpha1

CHANGES:

Added

• allow libraries with the same (name ..) in projects as long as they don't
  conflict during resolution (via enabled_if). (#10307, @anmonteiro,
  @jchavarri)

• dune describe pp now finds the exact module and the stanza it belongs to,
  instead of guessing the name of the preprocessed file. (#10321, @anmonteiro)

• Print the result of dune describe pp with the respective dialect printer.
  (#10322, @anmonteiro)

• Add new flag --context to dune ocaml-merlin, which allows to select a
  Dune context when requesting Merlin config. Add dune describe contexts
  subcommand. Introduce a field generate_merlin_rules for contexts declared
  in the workspace, that allows to optionally produce Merlin rules for other
  contexts besides the one selected for Merlin (#10324, @jchavarri)

• melange: add include paths for private library .cmj files during JS
  emission. (#10416, @anmonteiro)

• dune ocaml-merlin: communicate additional directives SOURCE_ROOT,
  UNIT_NAME (the actual name with wrapping) and INDEX with the paths to the
  index(es). (#10422, @voodoos)

• Add a new alias @ocaml-index that uses the ocaml-index binary to generate
  indexes that can be read by tools such as Merlin to provide project-wide
  references search. (#10422, @voodoos)

• merlin: add optional (merlin_reader CMD) construct to (dialect) stanza to
  configure a merlin reader (#8567, @andreypopp)

Changed

• melange: treat private libraries with (package ..) as public libraries,
  fixing an issue where import paths were wrongly emitted. (#10415,
  @anmonteiro)

• install .glob files for Coq theories too (#10602, @ejgallego)

Fixed

• Don't try to document non-existent libraries in doc-new target (#10319, fixes
  #10056, @jonludlam)

• Make dune-site's load_all function look for META files so that it
  doesn't fail on empty directories in the plugin directory (#10458, fixes
  #10457, @shym)

• Fix incorrect warning for libraries defined inside non-existant directories
  using (subdir ..) and used by executables using dune-build-info (#10525,
  @rgrinberg)

• Don't try to take build lock when running coq top --no-build (#10547, fixes
  #7671, @lzy0505)

• Make sure to truncate dune's lock file after locking and unlocking so that
  users cannot observe incorrect pid's (#10575, @rgrinberg)

• mdx: link mdx binary with byte_complete. This fixes (libraries) with
  foreign archives on Linux. (#10586, fixes #10582, @anmonteiro)

3.15.3

CHANGES:

Fixed

• Fix interpretation of exists_if predicate in META files of installed
  libraries containing more than one element. (#10564, fixes #10563, @dbuenzli,
  @nojb)

• Fix TSAN warning in wait4 stubs (#10554, fixes #10553, @emillon)

3.15.2

CHANGES:

Fixed

• If no directory targets are defined, then do not evaluate enabled_if
  (#10442, @rgrinberg)

• Fix a bug where Coq projects were being rebuilt from scratch each time the
  dependency graph changed. (#10446, fixes #10149, @Alizter)

3.15.1

CHANGES:

Fixed

• Fix overflow in sendfile stubs (copy of large files could fail or end with
  truncated files) (#10333, @tonyfettes)

• Fix crash when a rule with a directory target is disabled with enabled_if
  (#10382, fixes #10310, @gridbugs)

• melange: remove all restrictions around virtual libraries in Melange. They
  may be used as otherwise in libraries and executables. (#10412, @anmonteiro)

• spawn: fix compatibility with RHEL7 (#10428, @emillon)

3.15.0

CHANGES:

Added

• Add link flags to to ocamlmklib for ctypes stubs (#8784, @frejsoya)

• Remove some unnecessary limitations in the expansions of percent forms in
  install stanza. For example, the %{env:..} form can be used to select files
  to be installed. (#10160, @rgrinberg)

• Allow artifact expansion percent forms (%{cma:..}, %{cmo:..}, etc.) in
  more contexts. Previously, they would be randomly forbidden in some fields.
  (#10169, @rgrinberg)

• Allow %{inline_tests} in more contexts (#10191, @rgrinberg)

• Remove limitations on percent forms in the (enabled_if ..) field of
  libraries (#10250, @rgrinberg)

• Support dialects in dune describe pp (#10283, @emillon)

• Allow defining executables or melange emit stanzas with the same name in the
  same folder under different contexts. (#10220, @rgrinberg, @jchavarri)

Fixed

• coq: Delay Coq rule setup checks so OCaml-only packages can build in hybrid
  Coq/OCaml projects when coqc is not present. Thanks to @vzaliva for the
  test case and report (#9845, fixes #9818, @rgrinberg, @ejgallego)

• Fix conditional source selection with select on bigarray in OCaml 5
  (#10011, @moyodiallo)

• melange: fix inconsistency in virtual library implementation. Concrete
  modules within a virtual library can now refer to its virtual modules too
  (#10051, fixes #7104, @anmonteiro)

• melange: fix a bug that would cause stale import paths to be emitted when
  moving source files within (include_subdirs ..) (#10286, fixes #9190,
  @anmonteiro)

• Dune file formatting: output utf8 if input is correctly encoded (#10113,
  fixes #9728, @moyodiallo)

• Fix expanding dependencies and locks specified in the cram stanza.
  Previously, they would be installed in the context of the cram test, rather
  than the cram stanza itself (#10165, @rgrinberg)

• Fix bug with dune exec --watch where the working directory would always be
  set to the project root rather than the directory where the command was run
  (#10262, @gridbugs)

• Regression fix: sign executables that are promoted into the source tree
  (#10263, fixes #9272, @emillon)

• Fix crash when decoding dune-package for libraries with (include_subdirs qualified) (#10269, fixes #10264, @emillon)

Changed

• Remove the --react-to-insignificant-changes option. (#10083, @rgrinberg)

3.15.0~alpha2

CHANGES:

Fixed

• Backport #10327: fix a regression in dune install not performing artifact
  substitution.

3.14.2

CHANGES:

Fixed

• fix compilation on non-glibc systems due to signal.h not being pulled in
  spawn stubs. (#10256, @emillon)

3.14.1

CHANGES:

Fixed

• When a directory is changed to a file, correctly remove it in subsequent
  dune build runs. (#9327, fix #6575, @emillon)

• Fix a problem with the doc-new target where transitive dependencies were
  missed during compile. This leads to missing expansions in the output docs.
  (#9955, @jonludlam)

• coq: fix performance regression in coqdep unescaping (#10115, fixes #10088,
  @ejgallego, thanks to Dan Christensen for the report)

• coq: memoize coqdep parsing, this will reduce build times for Coq users, in
  particular for those with many .v files (#10116, @ejgallego, see also #10088)

• on Windows, use an unicode-aware version of CreateProcess to avoid crashes
  when paths contains non-ascii characters. (#10212, fixes #10180, @emillon)

3.14.0

CHANGES:

Added

• Introduce a (dynamic_include ..) stanza. This is like (include foo) but
  allows foo to be the target of a rule. Currently, there are some
  limitations on the stanzas that can be generated. For example, public
  executables, libraries are currently forbidden. (#9913, @rgrinberg)

• Introduce $ dune promotion list to print the list of available promotions.
  (#9705, @moyodiallo)

• If Sherlodoc is installed, add a search bar in generated HTML docs (#9772,
  @EmileTrotignon)

• Add only_sources field to copy_files stanza (#9827, fixes #9709,
  @jchavarri)

• The (foreign_library) stanza now supports the (enabled_if) field. (#9914,
  @nojb)

Fixed

• Fix $ dune install -p incorrectly recognizing packages that are supposed to
  be filtered (#9879, fixes #4814, @rgrinberg)

• subst: correctly handle opam files in opam/ subdirectory (#9895, fixes #9862,
  @emillon)

• Odoc private rules are not set up if a library is not available due to
  enabled_if (#9897, @rgrinberg and @jchavarri)

Changed

• When dune language 3.14 is enabled, resolve the binary in (run %{bin:..} ..) from where the binary is built. (#9708, @rgrinberg)

• boot: remove single-command bootstrap. This was an alternative bootstrap
  strategy that was used in certain conditions. Removal makes the bootstrap a
  bit slower on Linux when only a single core is available, but bootstrap is
  now reproducible in all cases. (#9735, fixes #9507, @emillon)
