CHANGES:

• Forbid multiple instances of dune running concurrently in the same workspace. (#6360, fixes #236, @rgrinberg)

• Allow promoting into source directories specified by subdir (#6404, fixes #3502, @rgrinberg)

• Make dune describe workspace return the correct root path (#6380, fixes #6379, @esope)

• Introduce a $ dune ocaml top-module subcommand to load modules directly without sealing them behind the signature. (#5940, @rgrinberg)

• [ctypes] do not mangle user written names in the ctypes stanza (#6374, fixes #5561, @rgrinberg)

• Support CLICOLOR and CLICOLOR_FORCE to enable/disable/force ANSI colors. (#6340, fixes #6323, @MisterDA).

• Forbid private libraries with (package ..) set from depending on private libraries that don't belong to a package (#6385, fixes #6153, @rgrinberg)

• Allow Byte_complete binaries to be installable (#4873, @AltGr, @rgrinberg)

• Revive $ dune external-lib-deps under $ dune describe external-lib-deps. (#6045, @moyodiallo)

• Fix running inline tests in bytecode mode (#5622, fixes #5515, @dariusf)

• [ctypes] always re-run pkg-config because we aren't tracking its external dependencies (#6052, @rgrinberg)

• [ctypes] remove dependency on configurator in the generated rules (#6052, @rgrinberg)

• Build progress status now shows number of failed jobs (#6242, @Alizter)

• Allow absolute build directories to find public executables. For example, those specified with (deps %{bin:...}) (#6326, @anmonteiro)

• Create a fake socket file _build/.rpc/dune on windows to allow rpc clients to connect using the build directory. (#6329, @rgrinberg)

• Prevent crash if absolute paths are used in the install stanza and in recursive globs. These cases now result in a user error. (#6331, @gridbugs)

• Add (glob_files <glob>) and (glob_files_rec <glob>) terms to the files field of the install stanza (#6250, closes #6018, @gridbugs)

• Allow :standard in the (modules) field of the coq.pp stanza (#6229, fixes #2414, @Alizter)

• Fix passing of flags to dune coq top (#6369, fixes #6366, @Alizter)

• Extend the promotion CLI to a dune promotion group: dune promote is moved to dune promotion apply (the former still works) and the new dune promotion diff command can be used to just display the promotion without applying it. (#6160, fixes #5368, @emillon)
