- Git-flow support
- Git: smarter rebase in case of diverged tracked branch
- Git (Windows): significant rebase performance improvements (20s vs. 6min - 18x faster on our XP test machine)
- custom SmartGit-URL support: smartgit://cloneRepo/
(supported, e.g. by [Gitblit](http://gitblit.com/)) - OS X: support for dock-icon clicks
