With no announcement prior to release and even a day after the Linux 3.8-rc5 was tagged, Torvalds went onto post a message on Google+ about the release earlier today, “Hey, Linux 3.8-rc5 is out, so go get it.”
From what Torvalds has written, the latest release candidate contains over 300 commits; has updates in btrfs, f2fs, ptrace and module loading. Torvalds has also revealed that the rc5 contains driver updates as well.
“…there’s also the usual driver updates – i915 and radeon, usb, serial, yadda yadda. But the drivers actually accounted for less than half of the patch this time around”, adds Torvalds.
