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 16.04 (code-named Xenial Xerus) is considered a so-called \acronym{LTS} version and is supported by Canonical with patches and upgrades for five years. The previous \acronym{LTS} version is Ubuntu 14.04 (Trusty Tahr), and has support for five years (until April 2019). Whenever a new LTS 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}.
