uTorrent 1.9 Alpha build 13910

µTorrent 1.9 Alpha build 13910 What is not in 1.9: 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. In addition we now implement NAT hole-punching for uTP connections, so connectivity should be improved for peers that do not have their ports mapped. 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. How to enable and disable it: Preferences > Advanced, set bt.transp_disposition to: 255 - both TCP and uTP (default) 10 - uTP only 5 - TCP only Changelog: --- 2008-12-24: Version 1.9 (build 13910) - Fix: never 'upload_only' in superseeding mode - Fix: total download byte counters --- 2008-12-20: Version 1.9 (build 13885) - Feature: NAT hole-punching (for uTP only) - Feature: account for uTP overhead when net.calc_overhead is true - Feature: Open URL in Browser for torrents - Feature: Right click menu in RSS history - Change: default net.calc_overhead to true - Change: Red RSS icon for broken feeds - Change: Bring back RSS icons for new and previously downloaded items - Change: Use feed name as label to torrents downloaded via RSS - Change: RSS dialog subscription wording - Change: URL column in RSS history - Change: Tweak RSS episode parser to better handle multi-episode feed items - Fix: uTP compatibility with 1.8.1 --- 2008-12-02: Version 1.9 (build 13582) - Change: add independent TCP and uTP, and queue length stats to Statistics dialog - Fix: another fix to trackers stuck in "updating..." - Fix: PEX address parsing bug - Fix: New Download message from RSS feed --- 2008-12-01: Version 1.9 (build 13559) - Fix: TCP connection queue when using uTP (fixed trackers stuck in "updating...") - Fix: re-connecting too quickly to peers when using uTP - Fix: crash/corrupt text with Advanced button in Add Torrent dialog --- 2008-11-24: Version 1.9 (build 13485) - Feature: uTP with rate balancing

In the utorrent forum, it says "This build is NOT suitable for general use."
it's still in Alpha, so there will be problems.
I recommend Waiting until they have a official release of 1.9.
