Nice :-) I was wondering when the next alpha's/beta's would be comming. Confused. What is that supposed to be? UDP tracker capability, UDP hole punching or ...? Where is more info? Same here, more info please. Both can mean a lot of things. Sidenote; I didn't see any options in the Advanced Settings to control these functions. What is not in 1.9: UDP hole punching (yet?) UDP tracker What is in 1.9: uTP, the micro transport protocol. This UDP-based reliable transport is designed to minimize latency, but still maximize bandwidth when the latency is not excessive. We use this for communication between peers instead of TCP, if both sides support it. In addition, we use information from this transport, if active, to control the transfer rate of TCP connections. This means uTorrent, when using uTP, should not kill your net connection - even if you do not set any rate limits. What was in 1.8.1: uTP, but connection attempts were not initiated by default, and there was no control over TCP as described above. You can enable it, but likely you will see the uTP connections not transfering much data, because they are pushed out of the way by TCP. What this means for rate control: You are still free to set rate limits and use external limiters. The "Automatic upload rate" control is flawed enough for most people that it will likely be removed once uTP is well tested and deployed, since it entirely supercedes that feature.
