• Project page: https://github.com/ocaml/dune
• Documentation: https://dune.readthedocs.io/

CHANGES:

• Do not ignore (formatting ..) settings in context or workspace files
  (refactor: introduce simpler env stanza db dune#8447, @rgrinberg)

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

• Fixed a bug where Dune was incorrectly parsing the output of coqdep when it
  was escaped, as is the case on Windows. (fix(coq): unescape \: to : dune#9231, fixes dune does not recognise paths starting with C:/ as absolute on Windows dune#9218, @Alizter)

• Copying mode for sandboxes will now follow symbolic links (fix: copy sandboxes should copy symlinks as well dune#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.
  ([coq] Correctly handle composed stdlib after coq lang 0.8 dune#9347, fixes [coq] Composition with (boot) theories is not working in Dune 3.8 dune#7909, @ejgallego)

• Fixed a bug where the (select) field of the (libraries) field of the
  (test) stanza wasn't working properly. (fix: dir_contents from select library dep in test stanza dune#9387, fixes select doesn't work in test stanza dune#9365, @Alizter)

• Allow to disable Coq 0.8 deprecation warning ([coq] Allow to disable Coq language deprecation warning. dune#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. (fix(init): correct behavior of PATH argument for dune init project dune#9447, fixes Initialize new project in current directory dune#9209, @shonfeder)

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

• Experimental doc rules: Correctly handle the case when a package depends upon
  its own sublibraries (Fix for #9456 dune#9461, fixes Incorrect dependency handling in new odoc rules. dune#9456, @jonludlam)

• Resolve various public binaries to their build location, rather than to where
  they're copied in the _build/install directory (fix: resolve installed binaries to local paths dune#9496, fixes [coq] Composition with (boot) theories hangs with a cycle in Dune > 3.7 when coq lang > 0.6 dune#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. (Add (explain) field to (menhir) stanza dune#9512, @nojb)

• Correctly ignore warning flags in vendored projects (refactor: introduce inherited fields in stanza db dune#9515, @rgrinberg)

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

• Remove warning 30 from default set for projects where dune lang is at least
  3.13 (Remove warning 30 from the standard set. dune#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. (Allow expansion in (modules) field dune#9578, @nojb)

• Use watch exclusions in watch mode on MacOS (fix: use standard_watch_exclusions with fsevents dune#9643, fixes dune build -w exclusion does not work in Mac OS dune#9517,
  @PoorlyDefinedBehaviour)

• Fix merlin configuration for (include_subdirs qualified) modules (fix: correctly output -open flags in merlin dune#9659,
  fixes (include_subdirs qualified) leads to some spurious ocaml-lsp errors dune#8297, @rgrinberg)

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

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

• ctypes: fix an error where (ctypes) with no (function_description) would
  cause an error trying refer to a nonexistent _stubs.a dependency (fix(ctypes): only function descriptions have stubs dune#9302,
  fix ctypes: missing rule for stubs when only using a type description dune#9300, @emillon)
