     Whether they are very stable or not will be determined by us
people who end up using them.  Long term support is up into
the higher 4.6 or 4.7 but 4.8 is on the way.

     As to why the numbers advanced so rapidly it was because
Linus Torvalds thought the long version numbers were a drag.
  It looked as though little progress was being made despite
frequent updates and security fixes.  So at one point he
decreed the next version was 3.0 then a year or so later to 4.x.
     Certain distributions use older kernels for whatever reason.
Probably to avoid problems with older tools.

     This is from a 4.4.4 kernel which is running nicely.
     I have several versions of the kernel running in previews and
  release candidates installed and running on my Dell E6420.
  They seem to do their jobs but the KDE 5.7 ain't there yet.

      You seem to be a bit behind the news but have you ever
read Distrowatch Weekly newsletter or bought a Linux magazine
in recent times?  Linux news is easy to find at places like
Linux Weekly News, Linux Planet, Linux Today, and Linux.com.
