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)

3.8.2

CHANGES:

• Switch back to threaded console for all systems; fix unresponsive console on
  Windows (#7906, @nojb)

• Respect -p / --only-packages for melange.emit artifacts (#7849, @anmonteiro)

• Fix scanning of Coq installed files (@ejgallego, reported by
  @palmskog, #7895 , fixes #7893)

• Fix RPC buffer corruption issues due to multi threading. This issue was only
  reproducible with large RPC payloads (#7418)

• Fix printing errors from excerpts whenever character offsets span multiple
  lines (#7950, fixes #7905, @rgrinberg)

3.8.1

CHANGES:

• Fix a crash when using a version of Coq < 8.13 due to the native compiler
  config variable being missing. We now explicitly default to (mode vo) for
  these older versions of Coq. (#7847, fixes #7846, @Alizter)

• Duplicate installed Coq theories are now allowed with the first appearing in
  COQPATH being preferred. This is inline with Coq's loadpath semantics. This
  fixes an issue with install layouts based on COQPATH such as those found in
  nixpkgs. (#7790, @Alizter)

• Revert #7415 and #7450 (Resolve ppx_runtime_libraries in the target context when
  cross compiling) (#7887, fixes #7875, @emillon)

3.8.0

CHANGES:

• Fix string quoting in the json file written by --trace-file (#7773,
  @rleshchinskiy)

• Read pkg-config arguments from the PKG_CONFIG_ARGN environment variable
  (#1492, #7734, @anmonteiro)

• Correctly set MANPATH in dune exec. Previously, we would use the bin/
  directory of the context. (#7655, @rgrinberg)

• Allow overriding the ocaml binary with findlib configuration (#7648,
  @rgrinberg)

• merlin: ignore instrumentation settings for preprocessing. (#7606, fixes
  #7465, @Alizter)

• When a rule's action is interrupted, delete any leftover directory targets.
  This is consistent with how we treat file targets. (#7564, @rgrinberg)

• Fix plugin loading with findlib. The functionality was broken in 3.7.0.
  (#7556, @anmonteiro)

• Introduce a public_headers field on libraries. This field is like
  install_c_headers, but it allows to choose the extension and choose the
  paths for the installed headers. (#7512, @rgrinberg)

• Load the host context findlib.conf when cross-compiling (#7428, fixes
  #1701, @rgrinberg, @anmonteiro)

• Add a coqdoc_flags field to the coq.theory stanza allowing the user to
  pass extra arguments to coqdoc. (#7676, fixes #7954 @Alizter)

• Resolve ppx_runtime_libraries in the target context when cross compiling
  (#7450, fixes #2794, @anmonteiro)

• Use $PKG_CONFIG, when set, to find the pkg-config binary (#7469, fixes
  #2572, @anmonteiro)

• Modules that were declared in (modules_without_implementation),
  (private_modules) or (virtual_modules) but not declared in (modules)
  will cause Dune to emit a warning which will become an error in 3.9. (#7608,
  fixes #7026, @Alizter)

• Preliminary support for Coq compiled intefaces (.vos files) enabled via
  (mode vos) in coq.theory stanzas. This can be used in combination with
  dune coq top to obtain fast re-building of dependencies (with no checking
  of proofs) prior to stepping into a file. (#7406, @rlepigre)

• Fix dune crashing on MacOS in watch mode whenever $PATH contains $PWD
  (#7441, fixes #6907, @rgrinberg)

• Fix dune install when cross compiling (#7410, fixes #6191, @anmonteiro,
  @rizo)

• Find pps dependencies in the host context when cross-compiling, (#7410,
  fixes #4156, @anmonteiro)

• Dune in watch mode no longer builds concurrent rules in serial (#7395
  @rgrinberg, @jchavarri)

• Dune can now detect Coq theories from outside the workspace. This allows for
  composition with installed theories (not necessarily installed with Dune).
  (#7047, @Alizter, @ejgallego)

• dune coq top now correctly respects the project root when called from a
  subdirectory. However, absolute filenames passed to dune coq top are no
  longer supported (due to being buggy) (#7357, fixes #7344, @rlepigre and
  @Alizter)

• Added a --no-build option to dune coq top for avoiding rebuilds (#7380,
  fixes #7355, @Alizter)

• RPC: Ignore SIGPIPE when clients suddenly disconnect (#7299, #7319, fixes
  #6879, @rgrinberg)

• Always clean up the UI on exit. (#7271, fixes #7142 @rgrinberg)

• Bootstrap: remove reliance on shell. Previously, we'd use the shell to get
  the number of processors. (#7274, @rgrinberg)

• Bootstrap: correctly detect the number of processors by allowing nproc to be
  looked up in $PATH (#7272, @Alizter)

• Speed up file copying on macos by using clonefile when available
  (@rgrinberg, #7210)

• Adds support for loading plugins in toplevels (#6082, fixes #6081,
  @ivg, @richardlford)

• Support commands that output 8-bit and 24-bit colors in the terminal (#7188,
  @Alizter)

• Speed up rule generation for libraries and executables with many modules
  (#7187, @jchavarri)

• Add --watch-exclusions to Dune build options (#7216, @jonahbeckford)

• Do not re-render UI on every frame if the UI doesn't change (#7186, fix
  #7184, @rgrinberg)

• Make coq_db creation in scope lazy (@ejgallego, #7133)

• Non-user proccesses such as version control or config checking are now run
  silently. (#6994, fixes #4066, @Alizter)

• Add the --display-separate-messages flag to separate the error messages
  produced by commands with a blank line. (#6823, fixes #6158, @esope)

• Accept the Ordered Set Language for the modes field in library stanzas
  (#6611, @anmonteiro).

• dune install now respects --display quiet mode (#7116, fixes #4573, fixes
  #7106, @Alizter)

• Stub shared libraries (dllXXX_stubs.so) in Dune-installed libraries could not
  be used as dependencies of libraries in the workspace (eg when compiling to
  bytecode and/or Javascript). This is now fixed. (#7151, @nojb)

• Allow the main module of a library with (stdlib ...) to depend on other
  libraries (#7154, @anmonteiro).

• Bytecode executables built for JSOO are linked with -noautolink and no
  longer depend on the shared stubs of their dependent libraries (#7156, @nojb)

• Added a new user action (concurrent ) which is like (progn ) but runs the
  actions concurrently. (#6933, @Alizter)

• Allow (stdlib ...) to be used with (wrapped false) in library stanzas
  (#7139, @anmonteiro).

• Allow parallel execution of inline tests partitions (#7012, @hhugo)

• Support (link_flags ...) in (cinaps ...) stanza. (#7423, fixes #7416,
  @nojb)

• Allow (package ...) in any position within (rule ...) stanza (#7445,
  @Leonidas-from-XIV)

• Always include opam files in the generated .install file. Previously, it
  would not be included whenever (generate_opam_files true) was set and the
  .install file wasn't yet generated. (#7547, @rgrinberg)

• Fix regression where Merlin was unable to handle filenames with uppercase
  letters under Windows. (#7577, @nojb)

• On nix+macos, pass -f to the codesign hook to avoid errors when the binary
  is already signed (#7183, fixes #6265, @greedy)

• Fix bug where RPC clients built with dune-rpc-lwt would crash when closing
  their connection to the server (#7581, @gridbugs)

• Introduce mdx stanza 0.4 requiring mdx >= 2.3.0 which updates the default
  list of files to include *.mld files (#7582, @Leonidas-from-XIV)

• Fix RPC server on Windows (used for OCaml-LSP). (#7666, @nojb)

• Coq language versions less 0.8 are deprecated, and will be removed
  in an upcoming Dune version. All users are required to migrate to
  (coq lang 0.8) which provides the right semantics for theories
  that have been globally installed, such as those coming from opam
  (@ejgallego, @Alizter)

• Bump minimum version of the dune language for the melange syntax extension
  from 3.7 to 3.8 (#7665, @jchavarri)

3.8.0~alpha3

• In (executable), (public_name -) is now equivalent to no (public_name).
  This is consistent with how (executables) handles this field.
  (#7576 , fixes #5852, @emillon)

• Change directory of odoc assets to odoc.support (was _odoc_support) so
  that it works with Github Pages out of the box. (#7588, fixes #7364,
  @emillon)
