We have a new Trillian Astra build this week, and thankfully this one will auto update. Build 68 features a full revamped to the [Yahoo] Voice Call system, and improved chat views. These features should be available in both the Cobalt and Cordonata skins. For more information on the changes, check out the developers blog.
If I had a guess, from the way things sound we may have one or two more “clean up” builds before they release the first beta.
