Adobe Lightroom Beta 2 is out. I haven’t spend much time with Beta 1 yet, but in case you want to try it… here’s the download link. Right now, RawDeveloper still works better for me. What’s new in Beta 2:

• Now a Universal Binary—this version runs on Apple’s latest Intel-based Macs.
• Crop and straighten your photos with new tools in the Develop module.
• Add music to your slideshows.
• Create nested keyword sets for easier organization.
• Import and export XMP metadata (*please see the Known Issues list for
  details).
• Try out the improved Edit in Photoshop capabilities.
• Take advantage of better metadata handling.
• Utilize new white balance support for the Nikon D2X, D2Hs, and D50 cameras.
