After eight Release Candidate versions, Linus Torvalds proudly announced a few minutes ago, December 11, the immediate availability for download of Linux kernel 3.7. Linux kernel 3.7 brings various interesting features (check out the highlights below and the quote from Linus Torvalds' announcement), among which we can mention support for 64-bit ARM, improved support for Intel and Radeon graphics cards, enhancements to the EXT4 and Btrfs filesystems, IPv6 Netfilter improvements, and much more.
"Whee. After an extra rc release, 3.7 is now out. After a few more trials at fixing things, in the end we ended up reverting the kswapd changes that caused problems."
"And with the extra rc, I had decided to risk doing the buffer.c cleanups that would otherwise have just been marked for stable during the next merge window, and had enough time to fix a few problems that people found there too." said Linus Torvalds in the official announcement.
