Firewalled ultrapeers will remain on the network until we release a new version and people upgrade. Changes to CVS will have no effect on existing clients.

There was a bug in the development version for a short time period that allowed an excess of Ultrapeer connections, but we fixed it rather quickly. I'm not positive when Jens-Uwe built his version, but if it contained the bug then that is bad, as it was a rather serious bug. (Whenever you handled a search for a leaf, you erased your list of connections.)

That's very strange (and very bad) that you had Leaf -> Ultrapeer connections, yet also had Ultrapeer -> Leaf and Ultrapeer -> Ultrapeer connections.

We'll take a close look at the connection logic to see what may be going wrong.

Thanks.
