The newest version of Citrix Provisioning Services has been released, the current version is now 5.1
You may have also noticed that it is called Services now as opposed to just Server. I think this was a good idea, it reflects more of what PVS is as opposed to it just being a Server.

You can download the latest version from the Citrix Downloads section below:
