All this talk of GTalk had me thinking about Adium, so I launched it. That's how I discovered that my favorite IM client had been updated to 0.83.
If you aren't familiar with Adium then you haven't been reading TUAW too carefully, it is the IM client of choice amongst the TUAW crew. It handles AIM, ICQ, Jabber, Yahoo!, and GTalk (or so it seems) that's just to name a few. It looks like .83 focuses on squashing lots of bugs and making the app all that more stable, you can feel free to read the version history, if you're into that kind of thing.
