Announced a few days ago. I am not optimistic about the future direction of uTorrent, given that Bittorrent, Inc has a deal with Warner Brothers (the enemy!). While I will continue to use the current version of uTorrent, I am already looking out for alternatives.
BitComet is definitely out, as it is still banned on a number of trackers due to it being considered harmful to the network, I am also not comfortable with the interface. BitLord, no, just no. Azureus is just too heavy for my poor little machine. ABC, BitTornado and the bevy of clients implemented in Python, lacking on some crucial features. Halite seems promising, but the libtorrent library it is based on lacks some features I need.
Since libtorrent has gained a higher profile thanks to the uTorrent situation, and I am hoping this will spur someone to get some heavy development work done to fill the gaps in its feature list, such as protocol encryption.
