Here's the
announcement and the
release notes.
Presumably CENTOS will catch up shortly.
Mostly looks like minor fixes, but I really like the sound of in-kernel persistent device naming (so that /dev/sdb is always the same device, regardless of what orders the buses and drives spin up) -- udev already does this with network interfaces. Though now that everybody uses DUIDs this is probably less of an issue. There is also some improved HyperV guest support (why?). Looking forward to trying this when CentOS brings out the gratis version soon.
