Linux 3.11-rc7 isn't particularly special itself as it's late in the release cycle and just offers up bug/regression fixes. However, in general, there is a lot of new features to the Linux 3.11 kernel.
Linus tagged 3.11-rc7 this afternoon and then made the following Google+ post to play on his original Linux announcement from 25 August 1991:
Hello everybody out there using Linux -The only other news from his 3.11-rc7 announcement today is that he hopes to have the Linux 3.11 kernel officially released within the next week or so.
I'm doing a (free) operating system (just a hobby, even if it's big and professional) for 486+ AT clones and just about anything else out there under the sun. This has been brewing since april 1991, and is still not ready. I'd like any feedback on things people like/dislike in Linux 3.11-rc7.
I originally ported bash(1.08) and gcc(1.40), but others have taken over user space and things still seem to work. This implies that I'll get the final 3.11 release within a week, and I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them :-)
Yeah, I don't really want to get feature requests this late in the rc series...
But it is 22 years today since that email, and I would like people to try the current 3.11-rc7 kernel I just cut and uploaded to the usual places.
