Actually, after 0.8 which is coming up soon, I am shifting to 3.5
Also, I have to say, I know it, well, sucks (I'd know, I had to do it myself too) but installing 0.8 will require you to wipe all your current torrents. That's due to a one time change in the torrent structure.
Sorry for any inconvinience, this is the only time I'm gonna ask you to do this.
On a sidenote, the server-client side of NuTT on my server has been running on 0.8 for almost a week and there are no complaints so far from my users.
The GUI has also gotten some iprovements, especially on the performance side.
So basically, I just need to add some features I've been long planning and after that I can release it
