Per-layer metadata comes to Photoshop
Fair warning: this is likely to be a pretty nerd-tastic blog entry, and it’s the kind of thing most people will never know or care about. Unless, that is, someone leverages it to do extremely cool, useful things. Right now it’s kind of a toss-up.
In summary, Photoshop’s scripting system can read and write parameters (keywords, descriptions, etc.) for each layer, meaning you can more richly tag layers with info–something that’s highly valuable when moving PSDs downstream into other apps. Adobe hasn’t yet leveraged this support to enable new features, but the support is in place for developers. Read on for the details.

The recent Camera Raw 4.6 release added the same support to Photoshop CS3. Note that if you’re not using CS3/CS4 or Lightroom 2, the free DNG Converter can make your files compatible with earlier versions and with other DNG-savvy software (not to mention smaller and more portable as well).
Lightroom 2.1 fixes are covered in this Read Me file.
Lightroom/ACR PM Tom Hogarty notes, "The beta versions of the Camera Profiles and DNG Profile Editor on Adobe Labs have also both been updated. The Profile update includes additional profiles and incremental improvements to the previous beta profiles. The DNG Profile Editor update includes minor enhancements."
