Dune 3.3.0

On behalf of the dune team, I’m pleased to announce the release of version 3.3.0. This is the first version that supports the upcoming OCaml 5.0. It also improves safety by sandboxing more rules and enabling more warnings, and there's a bunch of new features on the coq side too. Full changelog follows.

Note that as usual, dune works hard not to break existing packages. So even if it mentions that rules require precise dependencies, for example, this new safety net is only enabled for project that use (lang dune 3.3).

Happy hacking.

See full changelog
  • Sandbox preprocessing, lint, and dialect rules by default. All these rules now require precise dependency specifications (#5807, @rgrinberg)

  • Allow list expansion in the pps specification for preprocessing (#5820, @Firobe)

  • Add warnings 67-69 to dune's default set of warnings. These are warnings of the form "unused X.." (#5844, @rgrinberg)

  • Introduce project "composition" for coq theories. Coq theories in separate projects can now refer to each other when in the same workspace (#5784, @Alizter, @rgrinberg)

  • Fix hint message for data_only_dirs that wrongly mentions the unknown constructor data_only (#5803, @lambdaxdotx)

  • Fix creating sandbox directory trees by getting rid of buggy memoization (#5794, @rgrinberg, @snowleopard)

  • Handle directory dependencies in sandboxed rules. Previously, the parents of these directory dependencies weren't created. (#5754, @rgrinberg)

  • Set the exit code to 130 when dune is terminated with a signal (#5769, fixes #5757)

  • Support new locations of unix, str, dynlink in OCaml >= 5.0 (#5582, @dra27)

  • The coq.theory stanza now produces rules for running coqdoc. Given a theory named mytheory, the directory targets mytheory.html/ and mytheory.tex/ or additionally the aliases @doc and @doc-latex will build the HTML and LaTeX documentation repsectively. (#5695, fixes #3760, @Alizter)

  • Coq theories marked as (boot) cannot depend on other theories (#5867, @ejgallego)

  • Ignore bigarray in (libraries) with OCaml >= 5.0. (#5526, fixes #5494, @moyodiallo)

  • Start with :standard when building the ctypes generated foreign stubs so that we include important compiler flags, such as -fPIC (#5816, fixes #5809).
