The Linux Mint team published their May newsletter which indicates Linux Mint 18.2 will be released soon with a beta coming out in June. Some of the new features coming to 18.2 will include improved X-apps, the Cinnamon 3.4 desktop and MATE 1.18. The login screen will switch to using LightDM which includes built-in support for guest sessions. "Linux Mint 18.2 'Sonya' is just around the corner. The Cinnamon and MATE editions are currently in QA (functional testing) and we should be able to release them as BETA early this month. Cinnamon was upgraded to version 3.4 and MATE to version 1.18. The switch to LightDM was confirmed, with out of the box support for guest sessions and a beautiful login screen."
