Yes Ubuntu 22.04 LTS was just released in April 2022. It is in testing currently.
I do not have a official date. This is something we have been perusing since it was released.
It is normally best not to move on to the new OS until it has had a few months of burn-in time and packages, libraries, software stacks have been ported, tested and released.
This is much more solid than on the non-LTS branch, however, this is where the more production machines and applications are tested.
Once it is released, or I have a official time line I will try to update you here.
