This is a major change in the OCI support, as the format of the OCI image registries changed. Instead of now having a "ref" file for each image in the repo it has a single index json file, where the ref name is now a per-image annotation. This allows us to support OCI much better, as we can now use the actual flatpak ref as the OCI ref name, and we can find all the flatpak refs in a remote. So, with this you can just use: flatpak remote-add --oci remote-name URL and then you can use the regular flatpak operations on the remote.
