On May 31, 2014, with the release of Linux Mint 17, the Linux Mint team adopted a new release strategy. Starting with the release of Mint 17, all future versions were planned to use a LTS version of Ubuntu as a base, until 2016. Under this strategy, Mint 17.1 was released on November 29, 2014, Mint 17.2 was released on June 30, 2015, and Mint 17.3 was released on December 4, 2015. The 17.x releases are intended to be an easy, optional upgrade. All three versions included upgrades to the Cinnamon and MATE Desktop Environments and various Mint tools. In addition, Mint 17.2 and 17.3 included an upgrade to the LibreOffice suite. The 18.x series follows the pattern set by the 17.x series, by using Ubuntu 16.04 LTS as a base.
