As you may know, Q4OS is a Debian-based Linux system that uses Trinity Desktop as default and mimics Windows XP, while using a Linux Kernel.
Recently, the Q4OS developers have announced the release of Q4OS 2.0.2 “Scorpion” Beta, which uses Debian 9.0 Stretch as code-base, Trinity Trinity Desktop Environment 14.0.3 and Kernel 4.3 as default. The OS fixes some issues reported by some users and updated all the packages from the Debian repos to their versions as of January 6. Also worth mentioning, the OS has received an updated installer and will be updated five year from now, the stable version being expected to arrive in a few weeks from now.
