GNOME 51 launched September 16 with reworked Mutter frame scheduling, a Reduced Motion accessibility toggle, and, per OMG Ubuntu, FIDO2 passkey login support.

Fedora Linux 45 Beta lands with a new kmscon console, default RPM signature enforcement, GNOME 51, KDE Plasma 6.7, and an October 20 target for final release.

Canonical releases Ubuntu 26.04 LTS on April 23, shipping Rust-based coreutils and sudo as defaults, GNOME 50 without X11, and a 6 GB RAM floor that redefines the distribution's baseline for the next decade.

Ubuntu 26.04 LTS enters beta on March 26, shipping Rust-based coreutils and sudo, GNOME 50 without X11, post-quantum SSH, and AMD ROCm in official repositories.

GNOME 50 completely removes X11 from Mutter, Shell, and GDM, making Wayland the sole display protocol. The release stabilizes VRR and fractional scaling, and will ship in Ubuntu 26.04 LTS and Fedora 44.
