Based on the recently released Debian GNU/Linux 10.5 Buster update, Q4OS 3.12 is here to 3 and a half months after version 3.11 to update the long-term supported (LTS) Q4OS 3 Centaurus series with all the latest security and software updates from the Debian Stable repositories. This release ships with two editions featuring the Trinity Desktop Environment R14.0.8 and the more modern KDE Plasma 5.14.5 desktop environment. For the latter, there’s a new theme for you to try called Debonaire, which offers a dark panel and Kickoff applications menu.
