Last evening, on August 4, Linus Torvalds announced the immediate availability for download and testing of the fourth Release Candidate version of the upcoming Linux kernel 3.11.
Linux kernel 3.11 RC4 includes some arch updates (ARM, PA-RISC), updated drivers (networking, USB and DRM), as well as various core networking changes.
"I had hoped things would start calming down, but rc4 is pretty much exactly the same size as rc3 was. That said, the patches seem a bit more spread out, and less interesting – which is a good thing."
"Boring is good. Let's keep it that way, and try to make for fewer patches for -rc5, ok? Because we are past half-way now, and I really want to see just fixes.," Linus Torvalds said in the official release announcement
