• Do not ignore libraries named bigarray when they are defined in conjunction
  with OCaml 5.0 (fix: ignore [bigarray] correctly dune#8902, fixes Local libraries named bigarray are incorrectly removed dune#8901, @rgrinberg)

• Dependencies in the copying sandbox are now writeable (fix: make copying sandbox files writeable dune#8920, @rgrinberg)

• Absent packages shouldn't prevent all rules from being loaded (fix: load rules even if some packages aren't found dune#8948, fixes
  dune shouldn't require dependencies to be installed in order to run @fmt dune#8630, @rgrinberg)

• Correctly determine the stanza of menhir modules when (include_subdirs qualified) is enabled (@rgrinberg, fix(menhir): include_subdirs qualified dune#8949, fixes (include_subdirs qualified) clashes with nested Menhir parsers dune#7610)

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

• Re-run actions whenever (expand_aliases_in_sandbox) changes (fix: include expand aliases in digest dune#8990,
  @rgrinberg)

• Rules that only use internal dune actions (write-file, echo, etc.) can
  now be sandboxed. (fix: allow internal dune actions to be sandboxed dune#9041, fixes rfc(engine): sandbox only when needed rather than throwing an error dune#8854, @rgrinberg)

• Correctly ignore bigarray on recent version of OCaml (fix: properly ignore bigarray if it shouldn't exist dune#9076, @rgrinberg)

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

• 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)

• [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. (fix: failing coq --config dune#8966, fix
  [Coq] (stdlib no) broken since 3.8.0 dune#8958, @Alizter, reported by Lasse Blaauwbroek)

• Dune will now run at a lower framerate of 15 fps rather than 60 when
  INSIDE_EMACS. (dune_console: make refresh rate configurable and default INSIDE_EMACS to 15 dune#8812, @Alizter)

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

• Dune can now be built and installed on Haiku (feature: Haiku support dune#8795, fix unable to bootstrap on Haiku dune#8551, @Alizter)

• Mark installed directories in dune-package files. This fixes (package)
  dependencies against packages that contain such directories. (feat: record installed directories in dune-package dune#8953, fixes
  (package) dependencies do not work when directory targets are used dune#8915, @emillon)
