uTorrent 2.0 (build 17920)

(2010.01.25)

Release Notes:
We've added UDP tracker support!
uTP has been improved significantly 1.8.5, with many bugs fixed and performance improvements. It can be found in the preferences as "Enable bandwidth management" (but don't worry, you can still control caps!).
The setup dialog has been overhauled to make it much easier to use and with a built-in speed test. More presets were added and it automatically scales settings for high-upload connections.
A new transfer cap feature has been added to track bandwidth usage, along with graphs to show your usage.

Feature Overview:
UDP trackers are a different protocol for tracker communication that uses significantly less processing power on the tracker end. It's important for us to support this because trackers have limited resources, so this should allow them to support many more users with their current hardware and not crash under the load.

uTP is an alternative communication method for BitTorrent traffic that allows the client to automatically regulate its bandwidth usage to avoid adversely impacting your internet connection. This will allow you or other users on the network to download their torrents but still allow others on the network to function with little difference. This does not require any additional setup.
In addition, uTP in this version has added its own form of STUN, a method of getting incoming connections without direct connectivity to the Internet. This allows µTorrent to punch holes through routers and firewalls to increase connectivity and improve speeds. It is even possible to connect two firewalled peers through uTP's NAT traversal feature.

The transfer cap settings were added in response to various users who have ISP-mandated caps on how much data they can download/upload in a month. Now you can track your usage in MB (with a handy graph to visualize it) and even configure µTorrent to stop torrenting once the limits are exceeded. Currently, you can configure the time interval, the data cap and whether it should stop based on only download, upload, or both combined.
As a privacy notice, this traffic data is not sent back to us or anyone.
