Last April, Canonical He launched Ubuntu 22.04 and the rest of the Jammy Jellyfish family. It came with Linux 5.15, updated desktops like GNOME 42 and Plasma 5.24, and being an LTS version, which means it will be supported for 5 years (3 official flavors). It also means that they will be releasing ISO images with point updates, and the first one was due to arrive in August. Ubuntu 22.04.1 It's out now, and it's out a week late because they had to fix a major bug.
Ubuntu 22.04.1 are package updates and new ISOs. In both cases, they include all the news they have launched since last April, which include security patches, updated applications, and desktop components. What hasn't changed is the kernel, staying at Linux 5.15 that was included in the entire Jellyfish family. The kernel will not be updated until Ubuntu 22.10 is released and backported, something that can be avoided, but needs to be tweaked by the user.
Ubuntu 22.04.1 includes all updates since April
Among the novelties that arrive together with Ubuntu 22.04.1 we can mention that, finally (for those who were waiting for it), will default to Wayland on systems with NVIDIA hybrid cards, but it will remain in X11 for those who have or use 100% NVIDIA drivers.
The new images are already available from their respective web pages but, in case there is one that does not offer it on its portal, they can be downloaded from cdimage.ubuntu.com, accessing the desired version /releases/22.04.1. Canonical activates updates from an LTS version to a new LTS after the release of the first maintenance update of the next version, so Ubuntu 20.04 Focal Fossa users will soon be able to officially update from the same operating system.
Therefore, users who want to upgrade from Focal Fossa to Jammy Jellyfish can do so by simply installing all the packages. The Jammy Jellyfish have received the updates in the last 3-4 months.
