Along with Linux kernel 3.9.2, 3.0.78 LTS and 3.4.45 LTS comes the thirteenth and last maintenance release of Linux kernel 3.8, as announced by Greg Kroah-Hartman on May 11, 2013. Linux kernel 3.8.13 brings a lot of changes to the 3.8.x branch, as you can see from the raw changelog, but unfortunately it also reached End-Of-Life (EOL), which means that it will no longer be supported and all users are urged to upgrade to the stable 3.9.x branch.
