CHANGES:

3.20.2

CHANGES:

Fixed

• Fix jsoo separate compilation with modules_without_implementation. Regression
  introduced in #10767. (#12320, fixes #12306 @hhugo)

• Fix runtest-js mistakenly using wrong dependencies (#12324, @vouillon)

• Remove empty .cram.test.t directory during the running of a cram test.
  (#12329, fixes #12321, @Alizter)

• Fix Cygwin bootstrap (#12325, fixes #12316, @Alizter)

3.20.1

CHANGES:

Fixed

• Fix runtest-js mistakenly depending on byte (fixes #12243, #12242,
  @vouillon and @Alizter)

• Fix the interpretation of paths in dune runtest when running from within a
  subdirectory. (#12251, fixes #12250, @Alizter)

Changed

• Revert formatting change introduced in 3.20.0 making long lists in
  s-expressions fill the line instead of formatting them in a vertical way
  (#12245, reverts #10892, @nojb)

3.20.0

CHANGES:

Fixed

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

• fix: $ dune subst should not fail when adding the version field in opam
  files (#11801, fixes #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 (#11841, fixes #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. (#11558, grants part of #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. (#11109, partially fixes #10239, @Alizter)

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

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

• Introduce %{os}, %{os_version}, %{os_distribution}, and %{os_family}
  percent forms. These have the same values as their opam counterparts.
  (#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. (#11866, fixes #11212, @nojb)

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

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

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

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

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

• Added a (timeout <float>) field to the (cram) stanza to specify per-test
  time limits. Tests exceeding the timeout are terminated with an error.
  (#12041, @Alizter)

Changed

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

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

• Print a warning when dune build runs over RPC (#11833, @gridbugs)

• Stop emitting empty module group wrapper .js file in melange.emit
  (#11987, fixes #11986, @anmonteiro)
