On behalf of the dune team, I'm pleased to announce the 1.5.0 release of dune. This release does not contain any major features, but it does contain a few notable bug fixes and a couple of useful little additions. First of all, $ dune exec now supports C-c again - I know this affected many of you. This releases introduces a couple of new aliases that will hopefully find their way into your workflows.
The first alias is @all and has been much requested by our users. $ dune build @dir/all will build all user defined targets in a the directory dir. This would include binaries, libraries, and user defined targets in dir. This alias should have been the defaulted instead of @install when running $ dune build, but we'll have to wait until dune 2.0 to make this compatibility breaking change. In the mean time, I highly recommend everyone to use $ dune build @all instead of $ dune build meanwhile. You may also set the default alias per project as well:
(alias
(name default)
(deps (alias_rec all)))
The second new alias is @check. It is inspired by cargo's check subcommand and roughly corresponds to type checking the project and building all artifacts necessary for editor integration - cmt, cmti's, .merlin, etc. This is the fastest target to verify that a project is in a valid state. Note that this alias will not relink binaries so it might not catch errors such as missing stubs. I find this alias handy when doing large, type driven refactoring of a codebase.
The rest of the change log is replicated below. Happy hacking!

The highlight of this release is the improved support for menhir, in particular the long awaited --infer flag. This seemingly small feature took quite a bit of coordination between the maintainers of dune and menhir. So I'd like to thank @fpottier for helping us out with this by adding better support for dune in menhir itself, and implementing the majority of the support in dune as well.
The rest of the release is mostly bug fixes, but one notable feature is that dune is now C-c friendly. Dune will now resume exactly where it's stopped after interruption instead of restarting the entire build.
EDIT: I actually forgot to mention that this release also includes integration with OCamlFormat due to @emillon. Initially, I had thought that this feature was released in 1.3.0. Sorry about that!

A few weeks ago, we released a last release candidate to be later promoted to 2.0.0, synchronised with the opam package repository upgrade.
You are encouraged to update as soon as you see fit, to continue to get package updates: opam 2.0.0 supports the older formats, and 1.2.2 will no longer get regular updates. See the Upgrade Guide for details about the new features and changes.
The website opam.ocaml.org has been updated, with the full 2.0.0 documentation pages. You can still find the documentation for the previous versions in the corresponding menu.
Package maintainers should be aware of the following:

%{lib:name:file} forms (#1022, fixes #1019, @diml)It is my pleasure to announce the 1.0.0 release of Dune!
Dune is a built system for OCaml and Reason projects. It aims at building things fast and providing a smooth user experience.
Dune 1.0.0 is now available on github and in opam.
This is a big milestone for the project as it is the first release using the new Dune name that the community helped to choose. Dune started about a year and a half ago as the more narrow scoped Jbuilder and as since then proven itself to be the right tool for the job.
A big part of the work for this release was preparing the project for long-term support. Dune is the kind of project that will pretty much continue to evolve forever: it needs to keep up with the OCaml compiler evolving, development workflows changing, new kinds of tools with specific needs, etc... While doing so, it also needs to offer stability so that projects released now will continue to build with future versions of Dune.
Meeting these two constraints is a challenge. However, we had to do this for the renaming: we changed many things in Dune using what we learned from the Jbuilder experience. Still, Dune is able to understand and build Jbuilder projects. The mechanism used to support both Jbuilder and Dune projects is fully generic and will be the basis for future evolution.
You can find the full list of changes and bug fixes since Jbuilder 1.0+beta20 on the github release page. Following is an overview of some the new features:
General cleanup of the syntax: less parentheses, better behaved variables
Introduction of a dune.configurator library to help projects with C stubs detect and query the environment
General improvement of the default behavior: more parallelism by default, development mode by default
Better support for changing the defaults: it is now possible to set the default flags or change what dune build does by default
Support for setting the build directory
Better support for expectation tests on Windows

The major change is a new protocol that moves process management inside Merlin codebase, saving a lot of pain in Emacs and Vim. There are not much new user facing features.
Windows support is not yet available.
In editor configuration is now done with merlin-flags, merlin-extensions and merlin-use in Emacs and :MerlinFlags, :MerlinExtensions and :MerlinPackages in Vim. In previous versions, enabled extensions, flags and packages were retained while now only the last command is remembered.
"M-x merlin-use a", "M-x merlin-use b" should be replaced by "M-x merlin-use a,b". ":MerlinUse a", ":MerlinUse b" should be replaced by ":MerlinUse a b".
The old protocol is still supported, so existing editor modes should not be affected (tested with Atom, Visual Studio and Sublime-text).
Other main changes:
