Software update: µTorrent 2.1 build 18936 alpha

Not only was a new version from the 2.0.x development branch released on Wednesday, a new version was also released in the 2.1 branch, which should be considered alpha. New in version 2.1 is support for trackers and web seeds via magnet links, and for RSS feeds in the WebUI. That same WebUI now also uses encryption and would no longer require port forwarding. However, the intention is to add even more new functionality. Below is what has changed since build 18304:
