[emillon]

Fast, portable, and opinionated build system

• Project page: https://github.com/ocaml/dune
• Documentation: https://dune.readthedocs.io/

CHANGES:

• Add dune show rules as alias of the dune rules command. (show: print_rules now part of show command dune#8000, @Alizter)

• Fix %{deps} to expand properly in (cat ...) when containing 2 or more
  items. (test: expand %{deps} in (cat) dune#8196, @Alizter)

• Add dune show installed-libraries as an alias of the dune installed-libraries command. (show: add Installed_libraries to show dune#8135, @Alizter)

• Fix the severity of error messages sent over RPC which was missing. (fix(rpc): correct severity of error diagnostic dune#8193,
  @Alizter)

• Add dune build --dump-gc-stats FILE argument to dump garbage collection
  stats to a named file. (feature: add --dump-gc-stats option to dune build dune#8072, @Alizter)

• Fix bug with ppx and Reason syntax due to missing dependency in sandboxed
  action (fix: ppx and reason bug dune#7932, fixes ppx_expect + reason is broken after dune lang 3.2 dune#7930, @Alizter)

• Add dune describe package-entries to print all package entries (Add "dune describe package-entries" dune#7480,
  @moyodiallo)

• Improve dune describe external-lib-deps by adding the internal dependencies
  for more information. (Improve "dune describe external-lib-deps" : printing out more information  dune#7478, @moyodiallo)

• Re-enable background file digests on Windows. The files are now open in a way
  that prevents race condition around deletion. (fix: pass O_SHARE_DELETE when digesting files dune#8262, fixes background digests crash on Windows dune#8268, @emillon)

No regressions here, this is good to go as well.

Looks like ocamlformat-rpc could use a upper bound constraint on cmdliner to avoid its tests failing, but not a blocker to merge.
