## Changes for 2.2.1, r7434, 6-Mar-2007

## Changes for 2.2, r7421, 5-Mar-2007

### New requirements (Mac OS X only)

### New features

- You can now rate your photos.
- Raw conversion has been improved.

- Orientation changes (and ratings) are now stored in sidecar XMP files for interoperability with other applications.

  In previous versions of LightZone, orientation information was stored in a LightZone database. To preserve the orientation of photos you've already rotated, the first time your browse a folder with LightZone 2.2, it will create a new sidecar XMP file for every photo in that folder that's been rotated using LightZone's browser. If the folder is read-only, no XMP files can be created so orientation information will be lost for photos in that folder.

- The user interface has a darker and all-gray appearance to reduce color distractions.

### Camera support

- Nikon D40 raw files are now supported.

### Fixes (Mac OS X only)
