Ubuntu 24.04. The new LTS had dropped only two weeks ago. LTS users had a very outdated podman (4.9, two years old) and couldn't use quadlet types like build units (v5.2.0, aug 2024).
We are switching our Docker systems over to using Podman, primarily to get rid of the machinations we have to do to keep "apt update" from taking down services if there's a new Docker version. We're rolling them up from 24.04 to 26.04 and just using the podman packages on 26.04.
