Linux 3.8-rc5 was tagged on Friday, but no mailing list announcement by Linus Torvalds ever hit the wire. As of Saturday morning, there's still no 3.8-rc5 e-mail. However, Torvalds has announced the new test release to his Google+ page.
Hey, Linux 3.8-rc5 is out, so go get it.
I'll be traveling for LCA next week, so I'm hoping things are quieting down. They did not quiet down much for rc5, though, we still had 300+ commits in this rc. Not that they look all that scary, but there's more movement in btrfs, f2fs, ptrace and module loading than I'd really prefer at this stage.
Sure, 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.
Go forth and test.
