This is a short-term release with 9 months support. It so far features Linux Kernel 6.11 and GNOME 47 desktop.

To celebrate the 20th anniversary, the new release includes a “Warty Brown” accent color and new optional wallpapers in the “Appearances” settings page. There’s also an anniversary logo that you can see in the login screen.

/usr/bin/canberra-gtk-play --id="warty-startup"

This is great for security! But for lazy men those who don’t want to type user password again and again after logged in (or unlocked screen), it may be OK to disable the authentication window when using their computers at home or other safe places.

The last week was actually pretty quiet and calm, which is nice to see. The shortlog is below for anybody who wants to look at the details, but it really isn’t very many patches, and the patches are all pretty small.
