[pve-devel] Proxmox VE 7.3 released!

[Martin Maurer]

Hi all,

we're very excited to announce the release of Proxmox Virtual 
Environment 7.3. It's based on Debian 11.5 "Bullseye" but using a newer 
Linux kernel 5.15 or 5.19, QEMU 7.1, LXC 5.0.0, and ZFS 2.1.6.

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.
