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)

• Display cache location in Dune log (#8974, @nojb)

• 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)

3.11.1

CHANGES:

• Fix dune rpc commands on Windows (#8806, fixes #8799, @nojb)

• Fix inline_tests when the partition list is empty (#8849, fixes #8848, @hhugo)

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)

• Remove warning against .dune files generated by pre dune 2.0 (#8611,
  @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

CHANGES:

• Turn internal promote rules into fallback rules when
  --ignore-promoted-rules is set (#8518, #8706, fix #8417, fix #8703,

  that prevents race condition around deletion. (#8262, fixes #8268, @emillon)
