As a reminder, Linux Mint 17.2 RC images using either KDE or XFCE have been released a few days ago.
Linux Mint’s Clement Lefebvre has recently announced that the past 6 months were very busy for the developers, a lot of testing and bug-fixes being performed for Linux Mint 17.2. Also, the no-codecs and OEM images for Linux Mint 17.2 will be released soon.
In august 2015, the developers will start working on next Linux Mint 17.3, yet another Linux Mint system based on Ubuntu 14.04 Trusty Tahr.
As a reminder, Linux Mint has recently changed its release strategy and decided to adopt only the LTS versions of Ubuntu. Like Linux Mint 17 and Linux Mint 17.1, Linux Mint 17.2 Rafaela is based on Ubuntu 14.04 Trusty Tahr and uses latest generation desktop environments: Cinnamon 2.6 and MATE 1.10, but most likely, many Linux Mint-specific improvements have been implemented.
