Canonical released today Ubuntu 22.04.5 LTS as the fifth and last planned point release to the Ubuntu 22.04 LTS (Jammy Jellyfish) long-term supported operating system series bringing the latest security patches and updated components.

…

Apart from the security patches and updated packages that have been released during the past six months, the Ubuntu 22.04.5 LTS point release is powered by a newer kernel from the Ubuntu 24.04 LTS (Noble Numbat) operating system series, namely Linux kernel 6.8, to better support installations on newer hardware.

On the other hand, the Mesa graphics stack remains unchanged in this new Ubuntu 22.04 LTS point release, even though Ubuntu 24.04 LTS includes a newer version, namely Mesa 24.0. I don’t know why, but Canonical chose to ship Ubuntu 22.04.5 LTS with the Mesa 23.2.1 graphics stack that was also included in the Ubuntu 22.04.4 LTS point release.
