Release Naming Scheme

The official name of an Ubuntu release is "Ubuntu X.YY" with X representing the year (minus 2000) and YY representing the month of eventual release within in that year. Ubuntu's first release, made in 2004 October (10th month) was Ubuntu 4.10. Since the actual release date is not known until it's ready and humans tend to prefer names rather than numbers, a set of codenames are used by developers and testers during the buildup to a release:

The development codename of a release takes the form "Adjective Animal". So for example: Warty Warthog (Ubuntu 4.10), Hoary Hedgehog (Ubuntu 5.04), Breezy Badger (Ubuntu 5.10), are the first three releases of Ubuntu. In general, people refer to the release using the adjective, like "warty" or "breezy". The names live on in one hidden location---the archive release name in /etc/apt/sources.list and seen on the download mirror network.
