Now available for download, Linux 3.0 adds mostly minor changes to the open source operating system. “There are no special landmark features or incompatibilities related to the version number change,” Linux creator Linus Torvalds wrote, “it’s simply a way to drop an inconvenient numbering system in honor of twenty years of Linux.”
One major change that is included in the release is the incorporation of the Xen hypervisor. “Xen is better integrated into the mainstream kernel and this does benefit all users of Xen in the sense of better harnessing the power of community,” noted RedHat’s Tim Burke.
The update also includes improvements to the Btrfs filesystem.
