A brand new stable Q4OS 5.2 version codenamed 'Aquarius' is immediately available for download and use in production environments. This is a long-term support LTS version to be supported for at least five years with security patches and software updates. Q4OS Aquarius is based on Debian Bookworm 12 and Plasma 5.27.5, optionally Trinity 14.1.1 desktop environment, and it's available for 64bit/x64 computers. A 32bit/i686pae edition for older i386 systems with or without PAE extension will follow soon, in a few days. We plan to bring Aquarius for ARM devices as well. The objective is to provide rock stable, as lightweight as possible, Debian based operating system with added value thanks to unique Q4OS tools.
