I've just packaged and posted the final 1.0 release of a Twitter module for Gallery 3. Share photos, movies, and albums with your Twitter followers, directly from Gallery. Give it a try!
The next version of Gallery 3 is a complete rewrite from the ground up. It's coming along nicely thanks, in part, to jQuery and jQuery UI. Here's a bit of background on the project's decision to use jQuery and highlights of Gallery 3's theme system changes.
