The RefreshOS project has released RefreshOS 3.1, bringing an updated Debian foundation, a dedicated software repository, improved 32-bit application compatibility, and several refinements to its KDE Plasma desktop experience. Released on October 27, 2026, the update advances the distribution’s 3.x “Colorful Cosmos” series while introducing infrastructure that could significantly improve how RefreshOS delivers its own packages and configuration changes.
The new release moves from Debian 13.4 to Debian 13.7 “Trixie”, incorporates Linux kernel 6.12.113, and continues using KDE Plasma 6.3.6. However, the most important development is the introduction of an official RefreshOS APT repository with separate Stable, Testing, and Experimental channels. This gives the project a more structured way to distribute customized software while continuing to benefit from Debian’s established package ecosystem.
RefreshOS 3.1 also enables i386 architecture support, making it easier to install compatible 32-bit software and dependencies required by applications such as Steam. Additional changes address desktop localization, KDE integration, installer configuration, package permissions, and installation image cleanup. Together, these improvements represent an effort to make RefreshOS easier to maintain while preserving its focus on a ready-to-use Linux desktop.
RefreshOS Builds on Debian’s Stable Release Model
RefreshOS is a Debian-based Linux distribution developed by eXybit Technologies, designed to provide a polished desktop environment without requiring users to configure every component manually. The project combines Debian’s stable package foundation with KDE Plasma, preinstalled applications, hardware support, multimedia capabilities, and custom desktop styling.
Unlike distributions that emphasize constant adoption of the newest software versions, RefreshOS prioritizes a relatively predictable desktop experience. Its Debian foundation provides access to established security maintenance, package management, and compatibility practices, while RefreshOS adds its own configuration choices to simplify everyday use.
Version 3.1 continues that philosophy by incorporating Debian 13.7, the seventh point release of Debian 13 “Trixie.” Debian published this update on September 12, 2026, primarily to consolidate security corrections and fixes for significant software problems. These point releases do not represent entirely new Debian generations. Instead, they refresh installation media and package selections so newly installed systems begin with a more current collection of fixes.
