Synex 13 u10: recommended apps in Synex Package Manager and consolidated editions
Synex 13 u10 incorporates a new recommended applications section in Synex Package Manager, with one-click installation that automatically resolves external repositories and Flatpak support. This version also updates the system base, consolidates the COSMIC and Openbox editions incorporated during the u9 cycle, and adds a refinement in the Calamares installer for ZFS component management.
Adjustments for COSMIC users on Synex
With the COSMIC update to version 1.1.0 on Synex, there are two specific adjustments worth applying once on systems installed from earlier images. They apply to both the stable and semi-rolling branches.
Synex Semi-rolling now has its own APT repository
The Synex Semi-rolling branch now has its own dedicated suite in the official repository, separate from the stable branch. From now on, semi-rolling’s own packages —including COSMIC 1.1.0— are published and updated through this suite.
Synex Semi-rolling adds COSMIC 1.1.0, System76’s next-generation desktop
Synex brings COSMIC to its Semi-rolling branch with version 1.1.0, the latest release of the Rust-based desktop developed by System76. The edition is built on Debian testing and comes with a public repository containing the entire packaging work, reaffirming Synex’s commitment to transparency and reproducible work.

Synex 13 COSMIC: a new desktop edition based on COSMIC Epoch
We have added a new desktop edition based on COSMIC, the desktop environment developed by System76 and written entirely in Rust. This edition is built on the same stable Synex 13 base as the rest of the flavours, and includes the complete set of the project’s own tools. As part of this work, we also publish a GitHub repository with the scripts and patches needed to compile COSMIC and generate the deb packages on Debian 13 or any derivative distribution.

We’re excited to share something we’ve been working on: a first Synex image featuring COSMIC, the new desktop environment built entirely in Rust by System76.

The new Synex testing images update the system base, include Synex Package Manager 1.1.1 with held package management, importable/exportable software lists, and a new virtualized results table, and extend to the semi-rolling branch the system identity renewal through dpkg-divert already present in Synex 13 stable.
