Linus has released the 3.6 kernel. "When I did the -rc7 announcement a week ago, I said I might have to do
an -rc8, but a week passed, and things have been calm, and I honestly
cannot see a major reason to do another rc.
So here it is, 3.6 final."
Notable features in 3.6 include TCP small queues,
the client-side TCP fast open implementation
(server side should go in for 3.7), IOMMU groups, the Btrfs send/receive feature, the VFIO device virtualization mechanism, and
more. See the KernelNewbies
3.6 page (under construction as of this writing) for details.
