We are very excited to announce the general availability of Proxmox VE 5.3!

Proxmox VE now integrates CephFS, a distributed, POSIX-compliant file system which serves as an interface to the Ceph storage (like the RBD). You can store backupfiles, ISO images, and container templates. CephFS can be created and configured easily with its Metadata server (MDS) in the GUI.

We improved disk management and you can now add ZFS raid volumes, LVM, and LVMthin pools as well as additional disks with a traditional file system. The existing ZFS over iSCSI storage plug-in can now access LIO target in the Linux kernel. Other new features are nesting for LXC containers so you can use LXC and LXD inside containers or access NFS or CIFS. If you are adventurous, you can configure PCI passthrough and vGPUs via the GUI.

Countless bugfixes and more smaller improvements are listed in the release notes.
