3.11.0~alpha2

CHANGES:

• init: check that module names are valid (#8644, fixes #8252, @emillon)

• Add a new alias @doc-json to build odoc documentation in JSON format. This
  output can be consumed by external tools. (#8178, @emillon)

3.11.0~alpha1

CHANGES:

• Modules that were declared in (modules_without_implementation),
  (private_modules) or (virtual_modules) but not declared in (modules)
  will raise an error. (#7674, @Alizter)

• enabled_if now supports arch_sixtyfour variable (#8023, fixes #7997,
  @Alizter)- Use posix_spawn instead of fork on MacOS. This gives us a
  performance boost and allows us to re-enable thread. (#8090, @rgrinberg)

• Experimental: Added a $ dune monitor command that can connect to a running
  dune build in watch mode and display the errors and progress. (#8152,
  @Alizter)

• No longer emit linkopts(javascript) in META files (#8168, @hhugo)

• The progress RPC procedure now has an extra field for the In_progress
  constructor for the number of failed jobs. (#8212, @Alizter)

• Add a --preview flag to dune fmt which causes it to print out the changes
  it would make without applying them (#8289, @gridbugs)

• Introduce (source_trees ..) to the install stanza to allow installing
  entire source trees. (#8349, @rgrinberg)

• Deprecate install destination paths beginning with ".." to prevent packages
  escaping their designated installation directories. (#8350, @gridbugs)

• Stop signing source files with substitutions. Sign only binaries instead
  (#8361, fixes #8360, @anmonteiro)

• Add --stop-on-first-error option to dune build which will terminate the
  build when the first error is encountered. (#8400, @pmwhite and @Alizter)-
  Dune now displays the number of errors when waiting for changes in watch
  mode. (#8408, fixes #6889, @Alizter)

• Add with_prefix keyword for changing the prefix of the destination of
  installed files matched by globs. (#8416, @gridbugs)

• Added experimental --display tui option for Dune that opens an interactive
  Terminal User Interface (TUI) when Dune is running. Press '?' to open up a
  help screen when running for more information. (#8429, @Alizter and
  @rgrinberg)

• Add a warnings field to dune-project files as a unified mechanism to
  enable or disable dune warnings (@rgrinberg, 8448)

• dune exec: support syntax like %{bin:program}. This can appear anywhere
  in the command line, so things like dune exec time %{bin:program} now work.
  (#6035, #8474, fixes #2691, @emillon, @Leonidas-from-XIV)

• RPC message styles are now serialised meaning that RPC diagnostics keep their
  Ansi styling. (#8516, fixes #6921, @Alizter)- Ignore internal promote rules
  when --ignore-promoted-rules is set (#8518, fix #8417, @rgrinberg)

• Truncate output from actions that produce too much output (@tov, #8351)

• Allow libraries to shadow OCaml builtin libraries. Previously, builtin
  libraries would always take precedence. (@rgrinberg, #8558)

• Remove warning against .dune files generated by pre dune 2.0 (#8611,
  @rgrinberg)

• dune utop no longer links utop in "custom" mode, which should make this
  command considerably faster. (#8631, fixes #6894, @nojb)

• Ensure that package names in dune-project are valid opam package
  names. (#8331, @emillon)

• dune init: parse --public as a public name (#8603, fixes #7108, @emillon)

• Remove versions 0.1 and 0.2 of the experimental ctypes extension. (#8293,
  @emillon)

3.10.0

CHANGES:

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

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

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

• Fix the severity of error messages sent over RPC which was missing. (#8193,
  @Alizter)

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

• Fix bug with ppx and Reason syntax due to missing dependency in sandboxed
  action (#7932, fixes #7930, @Alizter)

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

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

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

3.9.3

CHANGES:

• Fix flushing when using sendfile fallback (#8288, @alan-j-hu)

  that prevents race condition around deletion. (#8262, fixes #8268, @emillon)

3.9.2

CHANGES:

• Disable background digests on Windows. This prevents an issue where
  unremovable files would make dune crash when the shared cache is enabled.
  (#8243, fixes #8228, @emillon)

• Fix permission errors when sendfile is not available (#8234, fixes #8120,
  @emillon)

3.9.1

CHANGES:

• Disable background operations and threaded console on MacOS and other Unixes
  where we rely on fork. (#8100, #8121, fixes #8083, @rgrinberg, @emillon)

• Initialize async IO thread lazily. (#8122, @emillon)

3.9.0

CHANGES:

• Validate file extension for $ dune ocaml top-module. (#8005, fixes #8004, @3Rafal)

• Include the time it takes to read/write state files when --trace-file is
  enabled (#7960, @rgrinberg)

• Add dune show command group which is an alias of dune describe. (#7946,
  @Alizter)

• Include source tree scans in the traces produced by --trace-file (#7937,
  @rgrinberg)

• Cinaps: The promotion rules for cinaps would only offer one file at a time no
  matter how many promotions were available. Now we offer all the promotions at
  once (#7901, @rgrinberg)

• Do not re-run OCaml syntax files on every iteration of the watch mode. This
  is too memory consuming. (#7894, fix #6900, @rgrinberg)

• Add --all option to dune rpc status to show all Dune RPC servers running.
  (#8011, fix #7902, @Alizter)

• Remove some compatibility code for old version of dune that generated
  .merlin files. Now dune will never remove .merlin files automatically
  (#7562)

• Add dune show env command and make dune printenv an alias of it. (#7985,
  @Alizter)

• Add additional metadata to the traces provided by --trace-file whenever
  --trace-extended is passed (#7778, @rleshchinskiy)

• Extensions used in (dialect) can contain periods (e.g., cppo.ml). (#7782,
  fixes #7777, @nojb)

• Allow (include_subdirs qualified) to be used when libraries define a
  (modules ...) field (#7797, fixes #7597, @anmonteiro)

• $ dune describe is now a command group, so arguments to subcommands must be
  passed after subcommand itself. (#7919, @Alizter)

• The interface and implementation fields of a (dialect) are now optional
  (#7757, @gpetiot)

• Add commands dune show targets and dune show aliases that display all the
  available targets and aliases in a given directory respectively. (#7770,
  grants #265, @Alizter)

• Allow multiple globs in library's (stdlib (internal_modules ..))
  (@anmonteiro, #7878)

• Attach melange rules to the default alias (#7926, @haochenx)

• In opam constraints, reject (and) and (or) with no arguments at parse
  time (#7730, @emillon)

• Compute digests and manage sandboxes in background threads (#7947,
  @rgrinberg)

• Add (build_if) to the (test) stanza. When it evaluates to false, the
  executable is not built. (#7899, fixes #6938, @emillon)

• Add necessary parentheses in generated opam constraints (#7682, fixes #3431,
  @Lucccyo)

3.8.3

CHANGES:

• Fix deadlock on Windows (#8044, @nojb)

• When using sendfile to copy files on Linux, fall back to the portable
  version if it fails at runtime for some reason (NFS, etc).
  (#8049, fixes #8041, @emillon)
