Docker edge version to Jammy distribution (ubuntu 22.04)

im using as sources.
until now i used ubuntu 20.04 with focal distribution and now i updated it to 22.04 which is Jammy distribution but i saw that there is no edge version there.
I have looked at the docs and its look like the last edge version released at the end of 2020.
So edge version has deprecated? its not released any more?
and there is no support for ubuntu 22.04 (Jammy) ?
