So, Kernel 3.13 has been implemented, Mesa 10.1.3 has been added by default and ALSA has been updated to version 1.0.25, support for UEFI has been added and a lot of updates and security fixes have been implemented, among others.
The Ubuntu LTS systems, the latest being Ubuntu 14.04 and Ubuntu 12.04 receive five point releases, allowing the users to download ISO images containing all the added updated and changes, so that the first system upgrade won’t be huge.
