System76 has released COSMIC Epoch 1.2.0, the second stable update to its all-Rust, Wayland-native desktop environment, arriving on June 30, 2026. The new tag brings a suite of usability improvements, including fixed workspace and launcher flickering, AVIF wallpaper support, proper MAC address validation in settings, and archive extraction stability in the file manager. Built entirely from scratch using the Iced toolkit and libcosmic, the desktop is now available across Pop!_OS, Arch, Fedora, NixOS, openSUSE, and Gentoo with over 6,400 GitHub stars. While the project is still iterating fast, these polish-focused changes mark a solid step toward a production-ready, modular Linux desktop that no longer relies on third-party frameworks.
