Proxmox Virtual Environment 7.3 comes with initial support for Cluster Resource Scheduling, enables updates for air-gapped systems with the new Proxmox Offline Mirror tool, and has improved UX for various management tasks, as well as interesting storage technologies like ZFS dRAID and countless enhancements and bugfixes.
