Linus Torvalds has announced the Linux Kernel 3.11. Here are the new features and how to install / upgrade new kernel in Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04 and Linux Mint.
Linus Torvalds wrote on the mailing list:
As some people noticed, I got distracted (“Ooh, look, a squirrel..”)
and never wrote an announcement for -rc7. My bad. But it wasn’t
actually all that interesting a release apart from the date, and it
had a silly compile error in ohci-pci if you hadn’t enabled
CONFIG_PM_RUNTIME, so we’ll just forget -rc7 ever happened, ok?
Instead, go and get the real 3.11 release, which is out there, all
shiny and ready to be compiled and loved.
Since rc7 (ok, I lied, it happened) there’s been just small fixes.
Most of them came in from the networking tree, but there’s some all
over: some random filesystem fixes, a couple of sound fixes, a
/proc/timer_list fix, things like that. Nothing really stands out
(unless you happened to use the new soft-dirty code, that had a buglet
that could really hurt), but let’s hope we don’t have some silly
configuration that doesn’t even compile this time around.
Shortlog appended.
