 - `podman` now uses the `netavark` network stack. Users will need to delete all of their local containers, images, volumes, etc, by running `podman system reset --force` once before upgrading their systems.

 - The EC2 image module no longer fetches instance metadata in stage-1. This results in a significantly smaller initramfs, since network drivers no longer need to be included, and faster boots, since metadata fetching can happen in parallel with startup of other services.
   This breaks services which rely on metadata being present by the time stage-2 is entered. Anything which reads EC2 metadata from `/etc/ec2-metadata` should now have an `after` dependency on `fetch-ec2-metadata.service`
