ALT Linux 4.1
All ALT Linux 4.1 distributions are based on branch/4.1. As for the moment of 4.1 Desktop release, packages in branch/4.1 are updated rather actively, so the branch itself is not intended to be used to update your installation or to install additional packages, you should use updates/4.1 repository instead. However, it is the best source of packages for those who want to test beta-versions of the upcoming distros, as well as for those who'd like to create a distro of their own.
Currently, there's the only distribution released on this branch.
