Linux 3.0 has been released. Technically, the release of version 3.0 of the Linux kernel shouldn't be too eventful, since the jump in version number doesn't actually signify any huge change or whatever; the only reason behind the bump to 3.0 is to come to saner version numbering. Still, man, it's like, totally version 3 of the Linux kernel.
