Since switching to the git-flow model for management of the branches in Gitorious mainline, new features don’t appear in master except in the form of new versions. This means that a few new versions have been released (and deployed to gitorious.org) which haven’t been annouced here.
We just pushed version 2.4.4 of Gitorious, the fourth patch version in the 2.4 series. There are no new features in this version, just a few bug fixes.
