1.7.1

CHANGES:

• Fix the watch mode (#1837, #1839, fix #1836, @diml)

• Configurator: Fix misquoting when running pkg-config (#1835, fix #1833,
  @Chris00)

1.7.0

CHANGES:

• Second step of the deprecation of jbuilder: the jbuilder binary
  now emits a warning on every startup and both jbuilder and dune
  emit warnings when encountering jbuild files (#1752, @diml)

• Change the layout of build artifacts inside _build. The new layout enables
  optimizations that depend on the presence of .cmx files of private modules
  (#1676, @bobot)

• Fix merlin handling of private module visibility (#1653 @bobot)

• unstable-fmt: use boxes to wrap some lists (#1608, fix #1153, @emillon,
  thanks to @rgrinberg)

• skip directories when looking up programs in the PATH (#1628, fixes
  #1616, @diml)

• Use lsof on macOS to implement --stats (#1636, fixes #1634, @xclerc)

• Generate dune-package files for every package. These files are installed and
  read instead of META files whenever they are available (#1329, @rgrinberg)

• Fix preprocessing for libraries with (include_subdirs ..) (#1624, fix #1626,
  @nojb, @rgrinberg)

• Do not generate targets for archive that don't match the modes field.
  (#1632, fix #1617, @rgrinberg)

• When executing actions, open files lazily and close them as soon as
  possible in order to reduce the maximum number of file descriptors
  opened by Dune (#1635, #1643, fixes #1633, @jonludlam, @rgrinberg,
  @diml)

• Reimplement the core of Dune using a new generic memoization system
  (#1489, @rudihorn, @diml)

• Replace the broken cycle detection algorithm by a state of the art
  one from this paper (#1489,
  @rudihorn)

• Get the correct environment node for multi project workspaces (#1648,
  @rgrinberg)

• Add dune compute to call internal memoized functions (#1528,
  @rudihorn, @diml)

• Add --trace-file option to trace dune internals (#1639, fix #1180, @emillon)

• Add --no-print-directory (borrowed from GNU make) to suppress
  Entering directory messages. (#1668, @dra27)

• Remove --stats and track fd usage in --trace-file (#1667, @emillon)

• Add virtual libraries feature and enable it by default (#1430 fixes #921,
  @rgrinberg)

• Fix handling of Control+C in watch mode (#1678, fixes #1671, @diml)

• Look for jsoo runtime in the same dir as the js_of_ocaml binary
  when the ocamlfind package is not available (#1467, @nojb)

• Make the seq package available for OCaml >= 4.07 (#1714, @rgrinberg)

• Add locations to error messages where a rule fails to generate targets and
  rules that require files outside the build/source directory. (#1708, fixes
  #848, @rgrinberg)

• Let Configurator handle sizeof (in addition to negative numbers).
  (#1726, fixes #1723, @Chris00)

• Fix an issue causing menhir generated parsers to fail to build in
  some cases. The fix is to systematically use -short-paths when
  calling ocamlc -i (#1743, fix #1504, @diml)

• Never raise when printing located errors. The code that would print the
  location excerpts was prone to raising. (#1744, fix #1736, @rgrinberg)

• Add a dune upgrade command for upgrading jbuilder projects to Dune
  (#1749, @diml)

• When automatically creating a dune-project file, insert the
  detected name in it (#1749, @diml)

• Add (implicit_transitive_deps <bool>) mode to dune projects. When this mode
  is turned off, transitive dependencies are not accessible. Only listed
  dependencies are directly accessible. (#1734, #430, @rgrinberg, @hnrgrgr)

• Add toplevel stanza. This stanza is used to define toplevels with libraries
  already preloaded. (#1713, @rgrinberg)

• Generate .merlin files that account for normal preprocessors defined using a
  subset of the action language. (#1768, @rgrinberg)

• Emit (orig_src_dir <path>) metadata in dune-package for dune packages
  built with --store-orig-source-dir command line flag (also controlled by
  DUNE_STORE_ORIG_SOURCE_DIR env variable). This is later used to generate
  .merlin with S-directives pointed to original source locations and thus
  allowing merlin to see those. (#1750, @andreypopp)

• Improve the behavior of dune promote when the files to be promoted have been
  deleted. (#1775, fixes #1772, @diml)

• unstable-fmt: preserve comments (#1766, @emillon)

• Pass flags correctly when using staged_pps (#1779, fixes #1774, @diml)

• Fix an issue with the use of (mode promote) in the menhir
  stanza. It was previously causing intermediate mock files to be
  promoted (#1783, fixes #1781, @diml)

• unstable-fmt: ignore files using OCaml syntax (#1784, @emillon)

• Configurator: Add which function to replace the which command line utility
  in a cross platform way. (#1773, fixes #1705, @Chris00)

• Make configurator append paths to $PKG_CONFIG_PATH on macOS. Previously it
  was prepending paths and thus $PKG_CONFIG_PATH set by users could have been
  overridden by homebrew installed libraries (#1785, @andreypopp)

• Disallow c/cxx sources that share an object file in the same stubs archive.
  This means that foo.c and foo.cpp can no longer exist in the same library.
  (#1788, @rgrinberg)

• Forbid use of %{targets} (or ${@} in jbuild files) inside
  preprocessing actions
  (#1812, fixes #1811, @diml)

• Add DUNE_PROFILE environment variable to easily set the profile. (#1806,
  @rgrinberg)

• Deprecate the undocumented (no_keep_locs) field. It was only
  necessary until virtual libraries were supported (#1822, fix #1816,
  @diml)

• Rename unstable-fmt to format-dune-file and remove its --inplace option.
  (#1821, @emillon).

• Autoformatting: (using fmt 1.1) will also format dune files (#1821, @emillon).

• Autoformatting: record dependencies on .ocamlformat-ignore files (#1824,
  fixes #1793, @emillon)

  first build (#1557, @aantron).

  a non sub directory with lang set to dune < 1.3 (#1486, fixes #1485,
  @NathanReb)

• Fix interpretation of paths in env stanzas (#1509, fixes #1508, @diml)

• Add context_name expansion variable (#1507, @rgrinberg)

• Use shorter paths for generated on-demand ppx drivers. This is to
  help Windows builds where paths are limited in length (#1511, fixes
