[ANNOUNCE] git-cinnabar 0.4.0

[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.

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

What's new since 0.3.2?

- Various bug fixes.
- Updated git to 2.11.0 for cinnabar-helper.
- Now supports bundle2 for both fetch/clone and push
  (https://www.mercurial-scm.org/wiki/BundleFormat2).
- Now supports `git credential` for HTTP authentication.
- Now supports `git push --dry-run`.
- Added a new `git cinnabar fetch` command to fetch a specific revision
  that is not necessarily a head.
- Added a new `git cinnabar download` command to download a helper on
  platforms where one is available.
- Removed upgrade path from repositories used with version < 0.3.0.
- Experimental (and partial) support for using git-cinnabar without
  having mercurial installed.
- Use a mercurial subprocess to access local mercurial repositories.
- Cinnabar-helper now handles fast-import, with workarounds for
  performance issues on macOS.
- 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.
- Fail graft earlier when no commit was found to graft
- Allow graft to work with git version < 1.9
- Allow `git cinnabar bundle` to do the same grafting as git push
