[ANN] dune.3.12.1

The Dune team is pleased to announce the release of Dune 3.12.

Note that due to a mistake during the release process, version 3.12.0 was not published to opam and should not be used. So here’s the changelog for 3.12.1.

Added

  • 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)

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

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

  • 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)

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

Changed

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

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

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

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

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

Fixed

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

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

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

  • [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)
