Hi beginners and developers,

we are happy to announce that we released new rebase-helper version 0.5.0.
GitHub [1].
There are several new features and bugfixes.

New features:
- building packages with fedpkg.
- rebases are now done by git rebase command.
- all operations with local git repositories are done by command git. No 
python binding is used currently.

Fixes:
- downloading new upstream sources.
- difftool has been removed because of we are using git rebase..
- fix problem with deleted patches.
- several python fixes.

Plan for release 0.6.0 are:
- fixing bugs and include rebase-helper into upstream monitoring service.
