[pve-devel] Proxmox VE 6.3 available

[Martin Maurer]

Hi all!

We are really excited to announce the general availability of our virtualization management platform Proxmox VE 6.3. The most notable new feature is the integration of the stable version 1.0 of our new Proxmox Backup Server. We have strong encryption on the client-side and we have made creating and managing encryption keys for you very simple, providing multiple ways to store keys. VM backups are blazing fast with QEMU dirty-bitmaps.


This release also brings stable integration of Ceph Octopus 15.2.6, and you can now select your preferred Ceph version during the installation process. Many new Ceph-specific management features have been added to the GUI like for example displaying the recovery progress in the Ceph status panel or setting the placement groups (PGs) auto-scaling mode for each Ceph pool in the storage cluster. In general, we have added even more functionality and usability enhancements to the GUI.


Proxmox VE 6.3 is built on Debian Buster 10.6 but uses the latest long-term support Linux kernel (5.4), QEMU 5.1, LXC 4.0, Ceph 15.2, and ZFS 0.85.


Countless bug fixes and smaller improvements are included as well, see the full release notes.
