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.
