Greg Kroah-Hartman, master of kernel stable releases, has declared Linux 3.10 to be this years long term stable kernel. That means he’ll be keeping releasing patches for it for “at least two years”, so folks putting together Linux distributions or products based on Linux can count on 3.10 for two years without a need to hop up a version or two to get a fix. Kroah-Hartman also mentions that LTSI, the project which manages a stable patchset for Linux in consumer electronics, is rebasing on 3.10 too.
What’s in 3.10? Thats where we point you to Thorsten Leemhuis’s “What’s new in 3.10” to give you some background.
