Dubbed Centaurus, the Q4OS 3.1 series of the open-source distro is based on the upcoming Debian GNU/Linux 10 “Buster” operating system, which currently lives in the Debian Testing repositories, and uses the development branch of the Trinity Desktop Environment (TDE), version 14.0.5. Despite the fact that it’s based on the Debian GNU/Linux operating system, every new Q4OS release comes with its own set of utilities and features that you probably won’t find anywhere else. These include the “Desktop profiler” tool for profiling your computer, and a “Setup utility” tool that makes installation of third-party apps easier.
