LTS releases 12.04 and newer are freely supported for five years. Through the ESM paid option, support can be extended even longer, up to a total of ten years for 18.04.

Ubuntu releases are also given

, ''e.g.'', "Dapper Drake". With the exception of the first two releases, code names are in alphabetical order, and except for the first three releases, the first letters are sequential, allowing a quick determination of which release is newer. As of Ubuntu 17.10, however, the initial letter "rolled over" and returned to "A". Names are occasionally chosen so that animal appearance or habits reflects some new feature, ''e.g.'', "Koala's favourite leaf is Eucalyptus"; see below. Ubuntu releases are often referred to using only the adjective portion of the code name, ''e.g.'', "Feisty".
