3.14.x is no longer the newest kernel that you can get for your distribution and its place has been taken by the 3.15 branch. Even if that is the case, this is still one of the most advanced releases that you can find and it's still a very popular choice for many Linux distributions.
The development for 3.14.x has been winding down now that 3.15 kernel is already out, and there are fewer changes and improvements in this latest update. It's still being maintained, but the focus has shifted to other branches.
“I'm announcing the release of the 3.14.8 kernel. All users of the 3.14 kernel series must upgrade.”
