Linus Torvalds announced the release today of the Linux 4.2-rc4 kernel, the fourth weekly snapshot of the in-development Linux 4.2.

This week Linus is unfortunately not too happy as there's still a lot of activity for being midway through the 4.2 release cycle. He noted, "I really wish that things were calming down, but it hasn't happened quite yet. It's not like this is particularly big or scary, but it's also not at the stage where it's really starting to get quiet and the bugs are really small and esoteric. So we still had some bugs due to the low-level x86 asm cleanup work, and the 32-bit compat 'syscall' instruction (only used on AMD) was subtly broken. That should be all fixed now, so if you run a 64-bit kernel and have 32-bit user space (including things like wine etc) and saw problems earlier, go ahead and update."
