The first monthly snapshot release for Ubuntu 26.04 LTS was released yesterday morning (UTC time).

Ubuntu development team announced this development snapshot:

Hello everyone, I’d like to announce the first successful publication of the monthly snapshot – Resolute Snapshot 1. You can find the images on cdimage.ubuntu.com …

As you may know, Ubuntu 26.04 is the next Long Term Support (LTS) release with 5 years standard support until 2031, plus Expanded Security Maintenance (ESM) support until 2036, and security coverage (for paid customers) until 2041.

Ubuntu 26.04 will use GNOME 50 as default desktop environment. According to Linux Kernel history release date, it will perhaps be powered by Kernel 6.20 (or 7.0).

According to the road map, the 26.04 release will also introduced 2 new default applications. It will replace Totem with Gnome core Showtime video player, and replace Gnome System Monitor with Resources system monitor and task manager.

And, it will continue improving the performance and stability for Wayland on NVIDIA, unify the package management experience, and update Security Center with ability to re-encrypt a disk and manage Ubuntu Pro features.

At the moment, the 26.04 Snapshot 1 still has GNOME 49, Kernel 6.17, and most features are not completed yet. You may keep an eye on this on-going release note page for the recent changes.
