Ubuntu 26.04 LTS, codenamed “Resolute Raccoon”, marks one of the most ambitious long‑term support releases Canonical has delivered in years. Scheduled for release on April 23, 2026, this update introduces sweeping improvements across performance, security, and the desktop experience. You can explore the full list of changes in Ubuntu’s official release notes .
Major System Upgrades
Ubuntu 26.04 ships with the Linux 7.0 kernel, which brings improved hardware support, better power efficiency, and enhanced performance for modern CPUs and GPUs. Details on kernel updates are available in the Linux kernel documentation .
On the desktop side, users will experience GNOME 50, a major leap forward that introduces a cleaner UI, faster animations, and improved multitasking. GNOME’s roadmap highlights these enhancements in the GNOME 50 release notes .
Notably, Ubuntu now uses Wayland as the exclusive display server, removing the legacy X11 session from the login screen—though XWayland remains for compatibility. Canonical explains this transition in its Wayland adoption notes .
System requirements have also increased: Ubuntu Desktop now needs 6GB RAM, up from 4GB in earlier LTS releases. Canonical outlines these changes in its hardware requirements guide .
Security & Under‑the‑Hood Enhancements
Security takes center stage in 26.04. The update includes a Rust‑based implementation of sudo, part of Ubuntu’s broader push toward memory‑safe components. More information is available in the sudo‑rs project documentation on GitHub .
Server‑side improvements include updated stacks such as PostgreSQL 18, Docker 29, and PHP 8.5, each documented in their respective PostgreSQL, Docker, and PHP release notes.
New Apps & User Experience
Several GNOME applications have been replaced with modern GTK4 alternatives, including Ptyxis, Papers, and Loupe. Ubuntu also introduces Showtime, a sleek new media player replacing Totem after more than a decade, highlighted in the Ubuntu Desktop blog .
