This version of uTorrent 1.8.1 will ignore the 'private' flag on any new torrents it opens. This will enable Peer Exchange and DHT on such torrents. I made this last time Demonoid went down when I noticed half my torrents were set to private and couldn't get any more peers. By patching up uTorrent I was able to finish my downloads.
Any private torrents currently on your list will need to be removed and re-added for them to be unlocked. Downloaded data will remain.
Note: If you run normal uTorrent after running this one it will re-lock all the private torrents.
