Ubuntu 14.04.2 LTS released + 15.04 ("Vivid Vervet") feature freeze
Ubuntu has announced the release of the second point release for its 14.04 long-term support (LTS). 14.04.2 comes with an updated kernel and X Window stack to support more hardware, along with "security updates and corrections for other high-impact bugs" all on updated installation media "so that fewer updates will need to be downloaded after installation". It is available for all of the members of the Ubuntu clan: Kubuntu, Edubuntu, Xubuntu, Mythbuntu, Ubuntu GNOME, Lubuntu, Ubuntu Kylin, and Ubuntu Studio.

One other note from the Ubuntu world: a feature freeze is in effect for 15.04 ("Vivid Vervet"), which is due in April.
