The highly anticipated Cosmic desktop environment has finally launched in alpha version alongside the Pop!_OS 24.04 alpha. The new Linux desktop environment is also available for Arch, Fedora, NixOS, and Serpent OS, with plans for openSUSE and Redox OS launches underway. https://www.notebookcheck.net/Cosmic-DE-previews-the-future-of-Linux-in-Pop_OS-24-04-alpha-with-Fedora-Serpent-OS-and-Arch-support-at-launch.873278.0.html
