The 3.7 kernel is out
Linus has released the 3.7 kernel.

"Anyway, it's been a somewhat drawn out release despite the 3.7 merge
window having otherwise appeared pretty straightforward, and none of
the rc's were all that big either. But we're done, and this means that
the merge window will close on Christmas eve." Of course, "drawn
out" is a relative term; at 72 days, this cycle is only a few days
above average in length.

Headline features in this kernel include 64-bit
ARM support, improved security with supervisor-mode access prevention,
SMB 2.1 support, server-side TCP fast
open support, signed kernel modules,
and more. See the
KernelNewbies 3.7 page for details.
