Hi all,

We are proud to announce the general availability of Proxmox Virtual Environment 6.4, our open-source virtualization platform. This version brings unified single-file restore for virtual machine (VM) and container (CT) backup archives stored on a Proxmox Backup Server as well as live restore of VM backup archives located on a Proxmox Backup Server.

Version 6.4 also comes with Ceph Octopus 15.2.11 and Ceph Nautilus 14.2.20, many enhancements to KVM/QEMU, and notable bug fixes. Many new Ceph-specific management features have been added to the GUI. We have improved the integration of the placement group (PG) auto-scaler, and you can configure Target Size or Target Ratio settings in the GUI.

The new version is based on Debian Buster 10.9, but using a newer, long-term supported Linux kernel 5.4. Optionally, the 5.11 kernel can be installed, providing support for the latest hardware. The latest versions of QEMU 5.2, LXC 4.0, and OpenZFS 2.0.4 have been included.

There are some notable bug fixes and smaller improvements, see the full release notes.
