RakuOS 2026.04.15

RakuOS Linux 2026.04.15 is a major release and our last major update for the Fedora 43 base as we begin to move towards Fedora 44, introducing our first COSMIC desktop edition ISO image, a new live ISO image installation experience, and full Rust rewrites of our core desktop applications. RakuOS Linux now ships its first COSMIC desktop ISO image, alongside our existing GNOME and KDE editions. Built on the System76 COSMIC desktop environment, it delivers a clean, modern experience on top of RakuOS's immutable, container-native foundation. Note of caution: COSMIC is still maturing and currently has some issues with gaming. If you are a gamer, we recommend holding off on the COSMIC edition until these issues are resolved by System76.
