Dune 1.2.0
══════════

  On behalf of the dune team, I'm pleased to announce the release of
  Dune 1.2.0.  This release contains many new goodies which I will not
  describe here. This is because Etienne Millon has prepared a blog post
  for this release:
  [https://gist.github.com/emillon/bab9b51d605dd018ea28728c05aa5c0b]

  I'd also like to personally thank him for all work he's done to make
  this release so great.

  As usual, the change log is replicated below for your convenience.

  Happy hacking!

1.2.0 (14/09/2018)
╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌

  • Ignore stderr output when trying to find out the number of jobs
    available (#1118, fix #1116, @diml)

  • Fix error message when the source directory of `copy_files' does not
    exist.  (#1120, fix #1099, @emillon)

  • Display actual stanza when package is ambiguous (#1126, fix #1123,
    @emillon)

  • Add `dune unstable-fmt' to format `dune' files. The interface and
    syntax are still subject to change, so use with caution. (#1130, fix

  • Improve error message for `dune utop' without a library name (#1154,
    fix #1149, @emillon)

  • Fix parsing `ocamllex' stanza in jbuild files (#1150, @rgrinberg)

  • Highlight multi-line errors (#1131, @anuragsoni)

  • Do no try to generate shared libraries when this is not supported by
    the OS (#1165, fix #1051, @diml)

  • Fix `Flags.write_{sexp,lines}' in configurator by avoiding the use
    of `Stdune.Path' (#1175, fix #1161, @rgrinberg)

  • Add support for `findlib.dynload': when linking an executable using
    `findlib.dynload', automatically record linked in libraries and
    findlib predicates (#1172, @bobot)

  • Add support for promoting a selected list of files (#1192, @diml)

  • Add an emacs mode providing helpers to promote correction files
    (#1192, @diml)

  • Improve message suggesting to remove parentheses (#1196, fix #1173,
    @emillon)

  • Add `(wrapped (transition "..message.."))' as an option that will
    generate wrapped modules but keep unwrapped modules with a
    deprecation message to preserve compatibility. (#1188, fix #985,
    @rgrinberg)

  • Fix the flags passed to the ppx rewriter when using `staged_pps'
    (#1218, @diml)

  • Add `(env var)' to add a dependency to an environment variable.
    (#1186, @emillon)

  • Add a simple version of a polling mode: `dune build -w' keeps
    running and restarts the build when something change on the
    filesystem (#1140, @kodek16)

  • Cleanup the way we detect the library search path. We no longer call
    `opam config var lib' in the default build context (#1226, @diml)

  • Make test stanzas honor the -p flag. (#1236, fix #1231, @emillon)

  • Test stanzas take an optional (action) field to customize how they
    run (#1248, #1195, @emillon)

  • Add support for private modules via the `private_modules' field
    (#1241, fix #427, @rgrinberg)

  • Add support for passing arguments to the OCaml compiler via a
    response file when the list of arguments is too long (#1256, @diml)

  • Do not print diffs by default when running inside dune (#1260,
    @diml)

  • Interpret `$ dune build dir' as building the default alias in
    `dir'. (#1259, @rgrinberg)

  • Make the `dynlink' library available without findlib installed
    (#1270, fix #1264, @rgrinberg)
