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… - -### What’s New in Kernel 4.2: ### - -- rewrites of Intel Assembly x86 code -- support for new ARM boards and SoCs -- F2FS per-file encryption -- The AMDGPU kernel DRM driver -- VCE1 video encode support for the Radeon DRM driver -- Initial support for Intel Broxton Atom SoCs -- Support for ARCv2 and HS38 CPU cores. -- added queue spinlocks support -- many other improvements and updated drivers. -
