Last evening, June 8, 2013, Linus Torvalds announced the immediate availability for download and testing of the fifth Release Candidate version of the upcoming Linux kernel 3.10.Linux kernel 3.10 RC5 includes updated drivers (networking, USB, MMC, GPU, sound, etc.), some arch updates (ARM, MIPS, arm, IA64, s390, x86, microblaze), networking (non-driver) improvements, as well as filesystem fixes (XFS, JFS, FUSE, GFS2, etc.).
"Yes, it's that time again - another week or so has passed, and a new release candidate is made in order to encourage and remind people to try things out."
"I wish I could say that things are calming down, but I'd be lying. rc5 is noticeably bigger than rc4, both in number of commits and in files changed (although rc4 actually had more lines changed, so there's that)," Linus Torvalds said in the official release announcement.
Download Linux kernel 3.10 RC5 right now from Softpedia. Remember that this is a development version and it should NOT be installed on production machines. It is intended for testing purposes only.
