Linux Kernel 4.0 with a unique name 'Hurr Durr I'm a sheep' was announced and the release as told above is not with some big changes. Linux Torvalds says in release post -

Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously "small" is all relative. It's still over 10k non-merge commits.

Feature-wise, 4.0 doesn't have all that much special. Much have been made of the new kernel patching infrastructure, but realistically, that not only wasn't the reason for the version number change,...

But he further says the next release will be a bigger release with some major changes and improvements.

...But we've definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones).

we've had much bigger changes in other versions. So this is very much a "solid code progress" release.
