Kernel release status
The current development kernel is 4.2-rc8, released on August 23. In the end, Linus
decided to wait one more week before putting out the final 4.2 release.
"
It's not like there are any real outstanding issues, and I waffled between just doing the release and doing another -rc. But we did have another low-level x86 issue come up this week, and together with the fact that a number of people are on vacation, I decided that waiting an extra week isn't going to hurt. But it was close. It's a fairly small rc8, and I really feel like it could have gone either way."
Previously, 4.2-rc7 came out on August 16.
Stable updates: 4.1.6, 3.14.51, and 3.10.87 were released on August 17.
