• Tile view. It's the big giant screenshots below. Check it out.
• Astra picked up the aliases and groups for all of my contacts on first load, on a machine that's never had Trillian before. That's a first, and definitely welcome.
• Astra seems to load much faster than the old version did. Before, it was somewhere between Photoshop and Acrobat Reader speed, now it's more like IE (but in a good way).
• There are options built-in for Google Talk and Myspace IM. I've never used Myspace IM, but I'll muck around with it as soon as I get some Myspace Friends. Google Talk support works really well.
• There are tons of color schemes for the default skin, and you can change between them without rebooting. You can even change between skins without rebooting. Very nice!
• There's some sort of news item in each message window. Not sure exactly what it's showing, sometimes it seems kind of like an ad, sometimes it's a news clip, sometimes it's random and funny. Also, you can browse back and forth; and it seems to change based on your conversation. Not sure if I like that, but I guess I don't mind Gmail doing the same thing.
• Widgets for weather, Flickr photos, and stuff like Twitter. Not sure why I need more widgets, but they're here. Apparently they'll communicate with other people on my contact list at some point, but not quite yet.

OK, now on to the screenshots and to bed with me!
