It's time for a new version! T-0.1.0 has a working single-port core, and users of launchmany will be receiving its benefits. launchmanycurses still needs some tweaking, though.
Aside from the new core, there have been several modifications to the engine. You may notice the client starts uploading (and therefore starts downloading better) more quickly after starting a new torrent. There've been several other tweaks and fixes incorporated.
For people waiting on the new multi-torrent GUI client, I'm afraid you'll have to wait a bit longer. Patience.
