60.

Canonical releases new versions of Ubuntu every six months; every fourth release is a so-called long-term support (\gls{LTS}) version. Each Ubuntu release has a version number that consists of the year and month number of the release, and an alliterative code name using an adjective and an animal. Code names are in consecutive alphabetic order, allowing a quick determination of which release is newer. Ubuntu 14.04 (code-named Trusty Tahr) is considered a so called LTS version and is supported by Canonical with patches and upgrades for five years. The previous \acronym{LTS} version is Ubuntu 12.04 (Precise Pangolin), and has support for five years (until April 2017). Whenever a new version of Ubuntu is released, we will incorporate updates and changes into our guide, and make a new version available at \url{http://www.ubuntu-manual.org}.
