Hi all!

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.
