The first beta of the upcoming openSUSE Linux 12.3, scheduled for final release on 13 March, is out and ready for testing: "According to plan, today openSUSE 12.3 beta sees the light. The beta comes with mostly smallish changes as we're in serious testing waters now – we hope you're out there to help us clear the way to the final release. The beta comes with 4.10 RC2 of KDE's workspaces and applications. KDE has announced a third RC due to some late changes and this version is part of a testing sprint organized by the KDE Quality team. openSUSE KDE packagers have build a special live image to test this release but we urge you to get the beta packages from software.opensuse.org as they are of course newer."
The openSUSE project is a community program sponsored by Novell.
Promoting the use of Linux everywhere, this program provides free, easy
access to openSUSE, a complete Linux distribution. The openSUSE project
has three main goals: make openSUSE the easiest Linux for anyone to
obtain and the most widely used Linux distribution; leverage open source
collaboration to make openSUSE the world's most usable Linux
distribution and desktop environment for new and experienced Linux
users; dramatically simplify and open the development and packaging
processes to make openSUSE the platform of choice for Linux developers
and software vendors.
