Sad to see, but it is really unstable I got crash when I tried to shut down program after I stopped downloading torrent, and I got crash while it working: and it won't work correctly with local peers. When I start stable 2.2.1 version - it found 3 local peers immediately and starts downloading at maximal speed I allowed. This alpha x64 found only one peer at the same torrent, but didn't get any speed advance from it.
