Linus Torvalds has just announced a few minutes ago, November 22, 2013, that the first Release Candidate of the upcoming Linux kernel 3.13 is now available for download and testing.
In numbers, Linux kernel 3.13 RC1 is comprised of mostly updated or new drivers (55%), architecture code (18%), network updates (9%), and the rest of of 28% represents filesystem updates, tools, headers, and documentation.
"So you had an extra week to prepare your pull requests, and if you were planning on sending it in the last two days thinking I'd close the merge window on Sunday as usual, I can only laugh derisively in your general direction, and call you bad names."
"Because I'm not interested in your excuses. I did warn people about this in the 3.12 release notes. As it was, there were a few people who cut it fairly close today. You know who you are." said Linus Torvalds in the official release announcement.
