# Using Ubuntu Linux/Master List of Ubuntu Releases

Ubuntu releases new versions every six months, and always supports them for at least 18 months with daily security fixes and patches to critical bugs. Some releases are designated as Long Term Support (LTS) versions, which have three years support for the desktop and five years for the server editions. It is intended that new LTS versions will be released every two years.
The most recent standard version, Ubuntu 15.10 (Wily Werewolf), was released on October 22, 2015.
The most recent LTS version, Ubuntu 16.04 (Wily Werewolf), was released on April 21, 2016
The next version of Ubuntu, Ubuntu 16.10, will be called Yakkety Yak.
Each finished release has both a code name and a version number. The version number is based on the year and month of release. For example, the very first "stable" release of Ubuntu (as opposed to development versions), Ubuntu 4.10, was released on October 20, 2004.
Releases are timed to be approximately one month after GNOME releases, which are in turn about one month after releases of X.org. Consequently, every Ubuntu release comes with a newer version of both GNOME and X.
The initial download and installation of Ubuntu is of course free of charge. In addition to the free updates, and support from the ubuntu community, and this guide, there are a number of other books about Ubuntu Linux, and paid technical support is available from Canonical Ltd.
