Transmission 2.0 gets ever lighter, still a top BitTorrent app for Mac and Linux
You might not notice many of the changes unless you're a BT guru, but you'll certainly notice the speed improvements. Transmission is now smarter about the order in which it connects to peers, better at optimizing the number of connections so you get the best speeds for your bandwidth, and doesn't take as long to verify local data when you resume a download. It also fully supports magnet links. Basically, you want this update.
For Mac users -- and maybe this was just a pet peeve of mine -- Resume All no longer restarts your already-finished transfers. I know it's a small thing, but it was really bugging me, and I'm glad the team of volunteers working on Transmission are paying such careful attention to details.
In case you're not sold yet, here's the full list of changes in Transmission 2.00.
