Apple has a support page for Aperture with more information. From there you can download the Late-Breaking News PDF. That document reveals that Aperture 2.0 supports trackpad gestures.

The troubleshooting links on the page are also handy (they are Knowledge Base articles). XLR8YourMac has collected a bunch of them together into a list which reproduce here:

• Aperture 2: Tips on migrating images to RAW 2.0
  
• Aperture 2: Some tips on Baseline DNG support
  
• Aperture 2: RAW 2.0 not available with some cameras
  
• Aperture 2: Some referenced images may be reimported even when Do Not Import Duplicates is selected
  
• Aperture 2: Newly supported images may not display properly after upgrade from Aperture 1.5.x to 2.0
  
• Aperture 2: Avoid making manual changes to your library structure
  
• Aperture 2: Avoid putting the computer to sleep while shooting tethered
  
• Aperture 2: Date on exported master image may be different in rare circumstances
  
• Aperture 2: Externally edited images are automatically located alongside originals
  
• Aperture 2: Tips on tethered shooting
  
• Aperture 2: Duplicate Images in library when tethering

AUPN has two articles that cover the new features: Part 1 and Part 2. As AUPN points out, lost in all the hoopla is the fact that Aperture 2.0 supports editing plug-ins. This will lead to all kinds of interesting things.
