I think there are one big regression with new versions of µTorrent. I currently still using 2.0.4, because 3.0 uses 50-60 MB RAM and more. While 2.0.4 - 30-40 MB in my case (604 torrents, 2-3 torrents - active). Can be that fixing in upcoming new versions or/and adding to to-do list of the future plans?
