Podman 4.0 will be fully released for the first time in Fedora 36. The API has had breaking changes so it will not be released to stable in Fedora 34 or Fedora 35. Podman 4.0 has a huge amount of changes and a brand new network stack.

Feedback

Alignment with Objectives:

Upgrade/compatibility impact

Podman 3.* release will not be able to connect to Podman 4.0 via remote API, similarly Podman 4.0 will not be able to connect to Podman 3.* API.

Existing network stack will continue to run, on existing systems. All containers and images need to be removed to try out the new network stack.

How To Test

Just test on existing systems. All Podman containers and images should continue to work. And all compatibility API (docker-compose, docker.py) should continue to work.
