3.13.0~alpha1

CHANGES:

• Do not ignore (formatting ..) settings in context or workspace files
  (#8447, @rgrinberg)

• Add command dune cache clear to completely delete all traces of the Dune
  cache. (#8975, @nojb)

• Fixed a bug where Dune was incorrectly parsing the output of coqdep when it
  was escaped, as is the case on Windows. (#9231, fixes #9218, @Alizter)

• Copying mode for sandboxes will now follow symbolic links (#9282, @rgrinberg)

• Forbid the empty (binaries ..) field in the env stanza in the workspace
  file unless language version is at least 3.2.

• [coq] Fix bug in computation of flags when composed with boot theories.
  (#9347, fixes #7909, @ejgallego)

• Fixed a bug where the (select) field of the (libraries) field of the
  (test) stanza wasn't working properly. (#9387, fixes #9365, @Alizter)

• Allow to disable Coq 0.8 deprecation warning (#9439, @ejgallego)

• Fix handling of the PATH argument to dune init proj NAME PATH. An
  intermediate directory called NAME is no longer created if PATH is
  supplied, so dune init proj my_project . will now initialize a project in
  the current working directory. (#9447, fixes #9209, @shonfeder)

• Allow OCAMLFIND_TOOLCHAIN to be set per context in the workspace file
  through the env stanza. (#9449, @rgrinberg)

• Experimental doc rules: Correctly handle the case when a package depends upon
  its own sublibraries (#9461, fixes #9456, @jonludlam)

• Resolve various public binaries to their build location, rather than to where
  they're copied in the _build/install directory (#9496, fixes #7908,
  @rgrinberg).

• Menhir: generate .conflicts file by default. Add new field to the
  (menhir) stanza to control the generation of this file: (explain <blang expression>). Introduce (menhir (flags ...) (explain ...)) field in the
  (env) stanza, delete (menhir_flags) field. All changes are guarded under
  a new version of the Menhir extension, 3.0. (#9512, @nojb)

• Correctly ignore warning flags in vendored projects (#9515, @rgrinberg)

• Directory targets can now be caches. (#9535, @rleshchinskiy)

• Remove warning 30 from default set for projects where dune lang is at least
  3.13 (#9568, @gasche)

• It is now possible to use special forms such as (:include) and variables
  %{read-lines:} in (modules) and similar fields. Note that the
  dependencies introduced in this way (ie the files being read) must live in a
  different directory than the stanza making use of them. (#9578, @nojb)

• Use watch exclusions in watch mode on MacOS (#9643, fixes #9517,
  @PoorlyDefinedBehaviour)

• Fix merlin configuration for (include_subdirs qualified) modules (#9659,
  fixes #8297, @rgrinberg)

• Fix handling of enabled_if in binary install stanzas. Previously, we'd
  ignore the result of enabled_if when evaluating %{bin:..} (#9707,
  @rgrinberg)

• Add coqdoc_flags field to coq field of env stanza allowing the setting
  of workspace-wide defaults for coqdoc_flags. (#9280, fixes #9139, @Alizter)

• ctypes: fix an error where (ctypes) with no (function_description) would
  cause an error trying refer to a nonexistent _stubs.a dependency (#9302,
  fix #9300, @emillon)

3.12.2

CHANGES:

• Fix version check in runtest_alias for cram stanza (#9454, @emillon)

• Fix stack overflow when a (run) action can not be parsed. (#9530, fixes
  #9529, @gridbugs)

CHANGES:

• Revert unintended inclusion of #9250 and #9280 (@emillon)

3.12.0

CHANGES:

• Introduce $ dune ocaml doc to open and browse documentation. (#7262, fixes
  #6831, @EmileTrotignon)

• dune cache trim now accepts binary byte units: KiB, MiB, etc. (#8618,
  @Alizter)

• No longer force colors for OCaml 4.03 and 4.04 (#8778, @rgrinberg)

• Introduce new experimental odoc rules (#8803, @jonjudlam)

• Introduce the runtest_alias field to the cram stanza. This allows
  removing default runtest alias from tests. (@rgrinberg, #8887)

• Do not ignore libraries named bigarray when they are defined in conjunction
  with OCaml 5.0 (#8902, fixes #8901, @rgrinberg)

• Dependencies in the copying sandbox are now writeable (#8920, @rgrinberg)

• Absent packages shouldn't prevent all rules from being loaded (#8948, fixes
  #8630, @rgrinberg)

• Correctly determine the stanza of menhir modules when (include_subdirs qualified) is enabled (@rgrinberg, #8949, fixes #7610)

• Re-run actions whenever (expand_aliases_in_sandbox) changes (#8990,
  @rgrinberg)

• Rules that only use internal dune actions (write-file, echo, etc.) can
  now be sandboxed. (#9041, fixes #8854, @rgrinberg)

• Do not re-run rules when their location changes (#9052, @rgrinberg)

• Correctly ignore bigarray on recent version of OCaml (#9076, @rgrinberg)

• Add test_ prefix to default test name in dune init project (#9257, fixes
  #9131, @9sako6)

• Add coqdoc_flags field to coq field of env stanza allowing the setting
  of workspace-wide defaults for coqdoc_flags. (#9280, fixes #9139, @Alizter)

• [coq rules] Be more tolerant when coqc --print-version / --config don't work
  properly, and fallback to a reasonable default. This fixes problems when
  building Coq projects with (stdlib no) and likely other cases. (#8966, fix
  #8958, @Alizter, reported by Lasse Blaauwbroek)

• Dune will now run at a lower framerate of 15 fps rather than 60 when
  INSIDE_EMACS. (#8812, @Alizter)

• dune-build-info: when version="" is found in a META file, we now return
  None as a version string (#9177, @emillon)

• Dune can now be built and installed on Haiku (#8795, fix #8551, @Alizter)

• Mark installed directories in dune-package files. This fixes (package)
  dependencies against packages that contain such directories. (#8953, fixes
  #8915, @emillon)

3.11.0

CHANGES:

• enabled_if now supports arch_sixtyfour variable (#8023, fixes #7997,
  @Alizter)

• Use posix_spawn instead of fork on MacOS. This gives us a performance
  boost and allows us to re-enable thread. (#8090, @rgrinberg)

• Experimental: Added a $ dune monitor command that can connect to a running
  dune build in watch mode and display the errors and progress. (#8152,
  @Alizter)

• The progress RPC procedure now has an extra field for the In_progress
  constructor for the number of failed jobs. (#8212, @Alizter)

• Add a --preview flag to dune fmt which causes it to print out the changes
  it would make without applying them (#8289, @gridbugs)

• Introduce (source_trees ..) to the install stanza to allow installing
  entire source trees. (#8349, @rgrinberg)

• Add --stop-on-first-error option to dune build which will terminate the
  build when the first error is encountered. (#8400, @pmwhite and @Alizter)

• Dune now displays the number of errors when waiting for changes in watch
  mode. (#8408, fixes #6889, @Alizter)

• Add with_prefix keyword for changing the prefix of the destination of
  installed files matched by globs. (#8416, @gridbugs)

• Added experimental --display tui option for Dune that opens an interactive
  Terminal User Interface (TUI) when Dune is running. Press '?' to open up a
  help screen when running for more information. (#8429, @Alizter and
  @rgrinberg)

• Add a warnings field to dune-project files as a unified mechanism to
  enable or disable dune warnings (@rgrinberg, 8448)

• dune exec: support syntax like %{bin:program}. This can appear anywhere
  in the command line, so things like dune exec time %{bin:program} now work.
  (#6035, #8474, fixes #2691, @emillon, @Leonidas-from-XIV)

• Make copy sandbox support directory targets. (#8705, fixes #7724, @emillon)

• Add a new alias @doc-json to build odoc documentation in JSON format. This
  output can be consumed by external tools. (#8178, @emillon)

• Modules that were declared in (modules_without_implementation),
  (private_modules) or (virtual_modules) but not declared in (modules)
  will raise an error. (#7674, @Alizter)

• No longer emit linkopts(javascript) in META files (#8168, @hhugo)

• Deprecate install destination paths beginning with ".." to prevent packages
  escaping their designated installation directories. (#8350, @gridbugs)

• RPC message styles are now serialised meaning that RPC diagnostics keep their
  Ansi styling. (#8516, fixes #6921, @Alizter)

• Truncate output from actions that produce too much output (@tov, #8351)

• Allow libraries to shadow OCaml builtin libraries. Previously, builtin
  libraries would always take precedence. (@rgrinberg, #8558)

  @rgrinberg)

• dune utop no longer links utop in "custom" mode, which should make this
  command considerably faster. (#8631, fixes #6894, @nojb)

• Ensure that package names in dune-project are valid opam package names.
  (#8331, @emillon)

• init: check that module names are valid (#8644, fixes #8252, @emillon)

• dune init: parse --public as a public name (#8603, fixes #7108, @emillon)

• Stop signing source files with substitutions. Sign only binaries instead
  (#8361, fixes #8360, @anmonteiro)

• Remove versions 0.1 and 0.2 of the experimental ctypes extension. (#8293,
  @emillon)

3.11.0~alpha3
