• Documentation: https://dune.readthedocs.io/

CHANGES:

• dune rules accepts aliases and other non-path rules (Allow dune rules to accept aliases as arguments dune#4063, @mrmr1993)

• Action (diff reference test_result) now accept reference to be absent and
  in that case consider that the reference is empty. Then running dune promote
  will create the reference file. (Simplify adding a rule that use a diff action dune#3795, @bobot)

• Ignore special files (BLK, CHR, FIFO, SOCKET), (Ignore special files (BLK, CHR, FIFO, SOCKET) dune#3570, fixes Exception in dune build when Unix domain socket in directory dune#3124, Crash if source directory contains a socket dune#3546,
  @ejgallego)

• Experimental: Simplify loading of additional files (data or code) at runtime
  in programs by introducing specific installation sites. In particular it allow
  to define plugins to be installed in these sites. (Sites, locations, relocation dune#3104, [Doc] Add explanation for sites in its own file dune#3794, fixes [RFC] Relocation library dune#1185,
  @bobot)

• Move all temporary files created by dune to run actions to a single directory
  and make sure that actions executed by dune also use this directory by setting
  TMPDIR (or TEMP on Windows). (Implement #3432 dune#3691, fixes Organize install_rules a little better dune#3422, @rgrinberg)

• Fix bootstrap script with custom configuration. (src/dune/setup.ml is now src/dune_rules/setup.ml dune#3757, fixes 2.7.1 fails to bootstrap dune#3774, @marsam)

• Add the executable field to inline_tests to customize the compilation
  flags of the test runner executable (add flexibility to compile a test executable dune#3747, fixes Compile flags dune#3679, @lubegasimon)

• Add (enabled_if ...) to (copy_files ...) (Support attaching MDX stanzas to packages dune#3756, @nojb)

• Make sure Dune cleans up the status line before exiting (Fix issue #3737 dune#3767,
  fixes Missing newline after build dune#3737, @alan-j-hu)

• Add {gitlab,bitbucket} as options for defining project sources with source
  stanza (source (<host> user/repo)) in the dune-project file. (Add support for gitlab/bitbucket sources dune#3813,
  @rgrinberg)

• Fix generation of META and dune-package files when some targets (byte,
  native, dynlink) are disabled. Previously, dune would generate all archives
  for regardless of settings. (Use Lib_info to generate install archives dune#3829, Fix archives for bytecode only dune#4041, @rgrinberg)

• Do not run ocamldep to for single module executables & libraries. The
  dependency graph for such artifacts is trivial (Do not run ocamldep on single module buildables dune#3847, @rgrinberg)

• Fix cram tests inside vendored directories not being interpreted correctly.
  (Fix cram & vendored dirs bug dune#3860, fixes Dune repo doesn't work with (vendored_dirs ..) dune#3843, @rgrinberg)

• Add package field to private libraries. This allows such libraries to be
  installed and to be usable by other public libraries in the same project
  (Private libraries attached to a package dune#3655, fixes Idea/Proposal: Allow for public libraries to depend on private libraries dune#1017, @rgrinberg)

• Fix the %{make} variable on Windows by only checking for a gmake binary
  on UNIX-like systems as a unrelated gmake binary might exist on Windows.
  (Fix %{make} on Windows dune#3853, @kit-ty-kate)

• Fix $ dune install modifying the build directory. This made the build
  directory unusable when $ sudo dune install modified permissions. (fix
  dune install with root permission should not create files in the build directory dune#3857, @rgrinberg)

• Fix handling of aliases given on the command line (using the @ and @@
  syntax) so as to correctly handle relative paths. (Uniformize handling of alias targets dune#3874, fixes dune build @../foo does not work dune#3850, @nojb)

• Allow link time code generation to be used in preprocessing executable. This
  makes it possible to use the build info module inside the preprocessor.
  (Use Exe to generate ppx executable dune#3848, fix Use Exe to generate ppx executable dune#3848, @rgrinberg)

• Correctly call git ls-tree so unicode files are not quoted, this fixes
  problems with dune subst in the presence of unicode files. Fixes Dune segfaults if the codebase contains some UTF-8 chars in (Coq) filenames dune#3219
  ([git] Correctly call git ls-tree so unicode files are not quoted dune#3879, @ejgallego)

• dune subst now accepts common command-line arguments such as
  --debug-backtraces ([dune subst] Interpret common command line flags. dune#3878, @ejgallego)

• dune describe now also includes information about executables in addition to
  that of libraries. ("dune describe" should include information about executables dune#3892, dune describe: include executables in output dune#3895, @nojb)

• instrumentation backends can now receive arguments via (instrumentation (backend <name> <args>)). (Passing arguments to instrumentation backends dune#3906, Add support for passing arguments to instrumentation backends dune#3932, @nojb)

• Tweak auto-formatting of dune files to improve readability. (dune formatting: style tweaks dune#3928, @nojb)

• Add a switch argument to opam when context is not default. (Add a switch argument to opam when context is not default dune#3951, @tmattio)

• Avoid pager when running $ git diff (Avoid running a pager when running 'git diff' dune#3912, @AltGr)

• Add (root_module ..) field to libraries & executables. This makes it
  possible to use library dependencies shadowed by local modules ((root_module ..) field for libraries & executables dune#3825,
  @rgrinberg)

• Allow (formatting ...) field in (env ...) stanza to set per-directory
  formatting specification. (Allow (formatting ...) field in (env ...) stanza. dune#3942, @nojb)

• [coq] In coq.theory, :standard for the flags field now uses the
  flags set in env profile flags ([coq] Add "-q" to default flags. dune#3931 , @ejgallego @rgrinberg)

• [coq] Add -q flag to :standard coqc flags , fixes [Coq] Use the flag -q by default dune#3924, ([coq] Add "-q" to default flags. dune#3931 , @ejgallego)

• Add support for Coq's native compute compilation mode (@ejgallego, [coq] Add support for native-mode compilation. dune#3210)

• Add a SUFFIX directive in .merlin files for each dialect with no
  preprocessing, to let merlin know of additional file extensions (.merlin: add a SUFFIX directive for each dialect dune#3977,
  @vouillon)

• Stop promoting .merlin files. Write per-stanza Merlin configurations in
  binary form. Add a new subcommand dune ocaml-merlin that Merlin can use to
  query the configuration files. The allow_approximate_merlin option is now
  useless and deprecated. Dune now conflicts with merlin < 3.4.0 and
  ocaml-lsp-server < 1.3.0 ([Wait for OcamlLSP] Disable promotion of .merlin files and work on ocaml-merlin server dune#3554, @voodoos)

• Configurator: fix a bug introduced in 2.6.0 where the configurator V1 API
  doesn't work at all when used outside of dune. (fix a bug in configurator String.take dune#4046, @aalekseyev)

• Fix libexec and libexec-private variables. In cross-compilation settings,
  they now point to the file in the host context. (Fix libexec variable behavior dune#4058, fixes The libexec variable doesn't expand to the host-context library in case of cross-compilation dune#4057,
  @TheLortex)

• When running $ dune subst, use project metadata as a fallback when package
  metadata is missing. We also generate a warning when (name ..) is missing in
  dune-project files to avoid failures in production builds.

• Remove support for passing -nodynlink for executables. It was bypassed in
  most cases and not correct in other cases in particular on arm32.
  (Never pass -nodynlink option dune#4085, fixes Cinaps stanza 1.0 fails to build the cinaps executable under arm32 dune#4069, fixes dune 1.11.0 fails to build on armv7 with odd relocation errors dune#2527, @emillon)

• Generate archive rules compatible with 4.12. Dune longer attempt to generate
  an archive file if it's unnecessary (Allow libraries without archives dune#3973, fixes dune runtest fails on OCaml 4.12.0 dune#3766, @rgrinberg)

• Fix generated Merlin configurations when multiple preprocessors are defined
  for different modules in the same folder. (Fix Merlin per-module pp flags dune#4092, fixes incorrect .merlin but no warning when using per_module dune#2596, per_module breaks .merlin output dune#1212 and
  incorrect .merlin containing -open Dune__exe dune#3409, @voodoos)

• Add the option use_standard_c_and_cxx_flags to dune-project that 1.
  disables the unconditional use of the ocamlc_cflags and ocamlc_cppflags
  from ocamlc -config in C compiler calls, these flags will be present in the
  :standard set instead; and 2. enables the detection of the C compiler family
  and populates the :standard set of flags with common default values when
  building CXX stubs. (Move default C flags to the :standard set dune#3875, Add necessary C++ flags for most common compilers dune#3802, fix [RFC] Rationalize C compiler flags dune#3718 and Better support for C++ dune#3528, @voodoos)
