Ubuntu 16.04, also known as the Xenial Xerus is a Long Term Support (LTS) release, providing five years of support. Canonical only releases new LTS updates every two years, with the last LTS, being the 14.04 ‘Trusty Tahr’ update in April 2014.
“This release is special because it’s an LTS, so not only do we support it for the next five years, but it becomes the foundation upon which many enterprises of all shapes and sizes build their IT infrastructure and products,” Jane Silber, CEO of Canonical said on a press conference call announcing Ubuntu 16.04.
