Linus Torvalds has just announced a few minutes ago, December 15, that the fourth Release Candidate of the upcoming Linux kernel 3.13 is now available for download and testing.According to Torvalds, Linux kernel 3.13 RC4 is yet another big release that includes mostly updated drivers (network, GPU, USB, media, etc.), various updates for the ARM architecture, SELinux updates, as well as networking improvements and other fixes.
"So I delayed this a couple of days to get back to my normal Sunday release schedule, but I'm not entirely happy with the result. Things aren't calming down the way they should be, and -rc4 is bigger than previous rc's [sic]. And I don't think I can just blame the two extra days."
"Anyway, what that means from a practical standpoint is that I'm going to be *very* grumpy at anybody who sends me unnecessary crap. If it's not regression or marked for stable, then just don't send it to me. Because you *will* be called names if you can't follow those simple rules. Comprende?" said Linus Torvalds in the official release announcement.
