New versions of Ubuntu are released by Canonical every 6 months. Every two years, the release is a Long Term Support version.
What support means
The table shows a list of currently supported release showing both original distribution releases (e.g. Ubuntu 14.04) and point releases (e.g. 14.04.3). The Ubuntu versions which are still supported will be delivered security updates.
Point releases include support for new hardware as well as rolling up all the updates published in that series to date. So a fresh install of a point release will work on newer hardware and will also not require a big download of additional updates.
