    [SOLVED] Kernel version number system


    Can someone explain to me how kernel version numbers work nowadays?

    When I started using Linux, it was simple: an odd minor version number indicated a development kernel and an even one a production kernel. But the kernel has been stuck at 2.26 for ages. Is there a 2.27 under development? Or does it now go by patch number?

    I notice that patch numbers are usually even, but not always. Crux is currently using 2.26.35.

    Ah! Well, according to this, it's rather like Ubuntu. You have a main, quasi-stable branch that gets updated every few months and periodic "long term support" snapshots, of which the latest is 2.6.27 (replacing 2.6.16). And the development fixes go into a different tree altogether. Thanks, Ozar.
