Now each release (patch) has a list of versions it can be applied to (e.g. "openstack_version" = "2013.2.3"; "can_update_openstack_versions" = ["2013.2.1", "2013.2.2"] for particular release). That's all. The history of patching is not recorded. It seems that we need to store it somehow to allow migrations to previous versions.
