May I ask to which online servers that you are referring? Both of the servers of which I am aware (that is, the Bridgewater-Brunel and the Stephenson-Seimens servers) use the latest nightly versions of both pakset and code.
The Bridgewater-Brunel server, however, is currently running only for debugging as there is a problem that is currently being investigated in which clients lose synchronisation and disconnect from the server.
