Ubuntu 22.04.3 LTS also includes a new hardware enablement stack (HWE) composed of Linux kernel 6.2 and Mesa 23.0.4 (a sizeable update in itself).
Package updates include GNOME Shell 42.9, LibreOffice 7.5.5 (an uplift over the the 7.3.x series), and Mozilla Firefox 116.
As a reminder, Ubuntu 22.04 LTS is supported until April 2027. Support beyond that is provided through an Ubuntu Pro subscription.
It’s been really solid here. I’m running it on 2 servers and 1 workstation and 1 laptop. It’s now got a recent enough version of Docker as well as SaltStack, if you’re into that. As a result I don’t use their repos anymore which helps with upgrades and they get security patches straight from Ubuntu. Also the free security updates for community packages is spectacular. I don’t think those are available in 20.04.
