CHANGES:

### Fixed

- Stop re-running cram tests after promotion when it's not necessary (ocaml/dune#11994,
  @rgrinberg)

- fix: `$ dune subst` should not fail when adding the version field in opam
  files (ocaml/dune#11801, fixes ocaml/dune#11045, @btjorge)

- Kill all processes in the process group after the main process has
  terminated; in particular this avoids background processes in cram tests to
  stick around after the test finished (ocaml/dune#11841, fixes ocaml/dune#11820, @Alizter,
  @Leonidas-from-XIV)

### Added

- `(tests)` stanzas now generate aliases with the test name. To run
  `(test (name a))` you can do `dune build @runtest-a`. (ocaml/dune#11558, grants part of ocaml/dune#10239,
  @Alizter)

- Inline test libraries now produce aliases `runtest-name_of_lib`
  allowing users to run specific inline tests as `dune build
  @runtest-name_of_lib`. (ocaml/dune#11109, partially fixes ocaml/dune#10239, @Alizter)

- feature: `$ dune subst` use version from `dune-project` when no version
  control repository has been detected (ocaml/dune#11801, @btjorge)

- Allow `dune exec` to run concurrently with another instance of dune in watch
  mode (ocaml/dune#11840, @gridbugs)

- Introduce `%{os}`, `%{os_version}`, `%{os_distribution}`, and `%{os_family}`
  percent forms. These have the same values as their opam counterparts.
  (ocaml/dune#11863, @rgrinberg)

- Introduce option `(implicit_transitive_deps false-if-hidden-includes-supported)`
  that is equivalent to `(implicit_transitive_deps false)` when `-H` is
  supported by the compiler (OCaml >= 5.2) and equivalent to
  `(implicit_transitive_deps true)` otherwise. (ocaml/dune#11866, fixes ocaml/dune#11212, @nojb)

- Add `dune describe location` for printing the path to the executable that
  would be run (ocaml/dune#11905, @gridbugs)

- `dune runtest` can now understand absolute paths as well as run tests in
  specific build contexts (ocaml/dune#11936, @Alizter).

- Added 'empty' alias which contains no targets. (ocaml/dune#11556 ocaml/dune#11952 ocaml/dune#11955 ocaml/dune#11956,
  grants ocaml/dune#4161, @Alizter and @rgrinberg)

- Allow `dune promote` to properly run while a watch mode server is running
  (ocaml/dune#12010, @ElectreAAS)

- Add `--alias` and `--alias-rec` flags as an alternative to the `@` and `@@`
  syntax in the command line (ocaml/dune#12043, fixes ocaml/dune#5775, @rgrinberg)

### Changed

- Format long lists in s-expressions to fill the line instead of
  formatting them in a vertical way (ocaml/dune#10892, fixes ocaml/dune#10860, @nojb)

- Switch from MD5 to BLAKE3 for digesting targets and rules. BLAKE3 is both more
  performant and difficult to break than MD5 (ocaml/dune#11735, @rgrinberg, @Alizter)

- Print a warning when `dune build` runs over RPC (ocaml/dune#11836, @gridbugs)

- Stop emitting empty module group wrapper `.js` file in `melange.emit`
  (ocaml/dune#11987, fixes ocaml/dune#11986, @anmonteiro)

  time limits. Tests exceeding the timeout are terminated with an error.
  (ocaml/dune#12041, @Alizter)
