Main article: List of Ubuntu releases

There are two Ubuntu releases per year, using the year and month of the release as the version number. The first Ubuntu release, for example, was Ubuntu 4.10 and was released on October 20, 2004.[53] Version numbers for future versions are provisional; if the release is delayed the version number changes accordingly.

Ubuntu releases are also given alliterative code names, using an adjective and an animal (e.g., "Dapper Drake" and "Intrepid Ibex"). With the exception of the first three releases, code names are in alphabetical order, allowing a quick determination of which release is newer. Commonly, Ubuntu releases are referred to using only the adjective portion of the code name.[54]

Releases are timed to be approximately one month after GNOME releases (which in turn are about one month after releases of X.org). Consequently, every Ubuntu release comes with an updated version of both GNOME and X. Selected releases (such as 6.06 Dapper Drake and 8.04 Hardy Heron) have been labeled as Long Term Support (LTS) versions, indicating that they are supported (with updates) for three years on the desktop and five years on the server,[55] as compared to the 18-month support period for non-LTS releases.[56]

The current release is 9.10 Karmic Koala,[57] released on October 29, 2009. Some users have reported hardware-recognition and functionality issues on upgrading to this version from previous versions of Ubuntu.[58] However, statistics based on the main Ubuntu support forum shows that the number of problems with 9.10 is no worse than average, though this doesn't include measurements of severity.
