[ANNOUNCE] git-cinnabar 0.4.0 release candidate

[Mike Hommey]

Hi,

Git-cinnabar is a git remote helper to interact with mercurial
repositories. It allows to clone, pull and push from/to mercurial remote
repositories, using git.

This release on
https://github.com/glandium/git-cinnabar/releases/tag/0.4.0rc

What's new since 0.4.0b3?

- Updated git to 2.10.2 for cinnabar-helper.
- Added a new `git cinnabar download` command to download a helper on
  platforms where one is available.
- Fixed some corner cases with pack windows in the helper. This prevented
  cloning mozilla-central with the helper.
- Fixed bundle2 support that broke cloning from a mercurial 4.0 server in
  some cases.
- Fixed some corner cases involving empty files. This prevented cloning
  Mozilla's stylo incubator repository.
- Fixed some correctness issues in file parenting when pushing changesets
  pulled from one mercurial repository to another.
- Various improvements to the rules to build the helper.
- Experimental (and slow) support for pushing merges, with caveats. See
  https://github.com/glandium/git-cinnabar/issues/20 for details about
  the current status. 

And since I realize I didn't announce beta 3:

What's new since 0.4.0b2?

- Properly handle bundle2 errors, avoiding git to believe a push
  happened when it didn't. (0.3.x is unaffected)
