According to Linus Torvalds Linux Kernel 4.2 may be the biggest release, as he stated on his Google Plus page.
Yesterday evening Linus Torvalds revealed interesting information about the next major version of the Linux kernel, which will be released within a few days as the first release candidate version.
On his Google Plus page Linux Torvalds states “4.0 was pretty small (by our modern standards, which is to say it was still a lot of changes), 4.1 was about average, and it looks like 4.2 may end up being the biggest release (in number of commits, at least) we’ve ever had.”
As you may have been used to Linux Kernel 4.2 would be released officially after 7 to 8 release candidate versions. The final release will probably available around fall 2015.
The development cycle of Linux kernel 4.2 might start this coming weekend with the first Release Candidate version, and it should have about seven or eight RC versions until the final release, which might see the light of day sometime in the fall of 2015.
