Unity 2.1 Released July 24 2008

Unity is now a complete MMO-capable engine. Brand new major features like streaming Asset Bundles, multiple stitchable Terrains make it possible to stream gigantic worlds to the player based on how they play.

For everyone else, we have lots of other delicious new features including procedural generation/modification of rigged characters & animations, shadows and projectors on Terrains, per-camera shader replacement, complete Undo and a lot more.
