New Google Talk Labs Editions Sports Group Chat and Notifications

http://www.google.com/talk/labsedition/ - Google Talk Labs Edition is the new version of the Google Talk desktop client. However, while some of the new features may prove useful in the future, it's not a full fledged upgrade.

This version of the desktop client now supports emoticons and group chat. You can even get notifications from Gmail, Google Calendar, and Orkut. However, several features from the original Google Talk app went away, which include voice chat and file transfers. So, If you still need these I suggest you stay with the the original version for now, until Google descides to blend the best of the two.
