-Linux Kernel 4.2 was released yesterday, at noon. Linus Torvalds wrote on [lkml.org][1]:
-
-> So judging by how little happened this week, it wouldn’t have been a mistake to release 4.2 last week after all, but hey, there’s certainly a few fixes here, and it’s not like delaying 4.2 for a week should have caused any problems either.
-> 
-> So here it is, and the merge window for 4.3 is now open. I already have a few pending early pull requests, but as usual I’ll start processing them tomorrow and give the release some time to actually sit.
-> 
-> The shortlog from rc8 is tiny, and appended. The patch is pretty tiny too…
