We introduce the new 'Software Centre' in this version, now it makes management of free applications much easier. We plan an important option for the Software Centre, which would allow direct purchasing of non-free applications and installing them in Q4OS seamlessly. The other notable change coming with the new Q4OS release is completion of several Welcome Screen translations, thanks to excellent work of external translators from different countries. A few internal improvements and bug fixes have been closed as usual.

The project's latest release, Q4OS 3.10, is based on Debian 10.2 "Buster" and offers better screen scaling for Trinity users. " The new 3.10 series brings important changes for key Q4OS desktop environments, Plasma and Trinity. Both desktops are now much more independent one on each other, Q4OS Plasma doesn't require presence of the Trinity desktop anymore. As a positive side effect, we could significantly reduce size of the Plasma installation media. In addition to adoption the Debian Buster 10.2 release, we have included a dedicated hardware reporting tool into both Plasma and Trinity live media. Screen scaling tool for Trinity desktop has been even improved again. Plasma Debonaire theme has been polished, so it now looks a bit darker.

Distribution Release: Q4OS 3.8 Q4OS is a lightweight Linux distribution based on Debian. The distribution's latest release is Q4OS 3.8 which is available in two desktop editions: KDE Plasma and Trinity. " Q4OS Centaurus is based on Debian Buster 10 and Plasma 5.14, optionally Trinity 14.0.6, desktop environment, and it's available for 64-bit and 32-bit/i686 PAE computers, as well as for older i386 systems without PAE extension. We are working hard to bring it for ARM devices too. One of the Q4OS specific goals is the ability to have Plasma and Trinity desktop alongside each other installed. Users can switch back and forth between more advanced Plasma or efficient Trinity desktop. Both desktops can independently coexist side by side and don't interfere with each other. Plasma is being the logical primary choice for most of users, so it's considered to be the default option, which is also obvious from the Q4OS downloads site.
