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)
