The first beta release of openSUSE 13.1 is now available and making the cut before the feature freeze was the Linux 3.11 kernel and Mesa 9.2.0.
Along with the Linux 3.11 kernel and Mesa 9.2.0, some other notable packages that got upgraded at the last minute were LLVM/Clang 3.3, systemd 207, PHP 5.4.19, BlueZ 5, Wine 1.7, Samba 4.1, KDE SC 4.11.1, and Amarok 2.8.
OpenSUSE 13.1 has mostly brought a wide assortment of package updates and other small changes
though internally it's notable for switching to a Ruby-based version of YaST
The plan in pushing openSUSE 13.1 out the door is to do two release candidates in October followed by the final release in mid-November (19 November). More details on today's beta release can be found at news.opensuse.org
