Linus Torvalds, the creator of Linux, finally announced the Linux Kernel 3.14 on the night of March 30, 2014. He wrote on the lkml.org:

So we had a few fairly late changes that I could have done without, but the changelog from -rc8 is still pretty small, and I’m feeling pretty good about it all. If we did end up with any last-minute problems due to the final spurt of patches, they’ll be pretty specific, and it really didn’t make sense to me to delay the release without anything known pending. Much of the final spurt were either marked for stable or known regressions.

So 3.14 is out there, and the merge window for 3.15 is thus open. Please do spend the time to test out 3.14, though, even if you might otherwise be in a hurry to send me your pending queue for the next release.
