Ubuntu Release Manager Kate Stewart has announced that Ubuntu 11.04, code-named "Natty Narwhal", reached its end of life yesterday, 28 October. This means that no new updates, including security updates and critical fixes, will be made available for version 11.04 of Canonical's Linux distribution.

Released in April 2011, Natty Narwhal was based on the 2.6.38.2 Linux kernel and was the first version of Ubuntu to replace the GNOME Shell with Unity as its default desktop environment. Firefox 4.0, version 3.3.2 of the LibreOffice productivity suite and Banshee 2.0 were among the bundled default applications.

Users still running Ubuntu 11.04 are advised to upgrade to version 11.10 "Oneiric Ocelot" or later in order to continue receiving updates. Those wanting to upgrade to the current Long Term Support edition, Ubuntu 12.04, or the most recent standard release, Ubuntu 12.10 "Quantal Quetzal", will need to upgrade in multiple steps, first upgrading to 11.10 and then the subsequent versions.
