Software update: µTorrent 2.1 build 18304 alpha

Not only did a new version from the 2.0.x development branch appear on Wednesday, a new version was also released in the 2.1 branch, which should be regarded as alpha. New in version 2.1 is support for trackers and web seeds via magnet links and for RSS feeds in the WebUI. The same WebUI now also uses encryption and would no longer require port forwarding. However, the intention is that even more new functionality will be added. Below is what has changed since build 17350:
