I'm trying to decode the release notes
Added a new preference to put photo preferences for tag and color class into IPTC/XMP so that an external editor that preserves IPTC/XMP will retain the tag and color class when a photo is edited and saved as a new photo. You can choose to have this done for RAW photos only, for all photos, or not at all. However, when the IPTC/XMP is updated for a photo, the tag and color class will be added to the IPTC/XMP regardless of the preference setting. If you choose to set the preference for all photos, then tagging or setting the color class for JPEGs and PSD files can be much slower since the IPTC/XMP may need to be inserted into the photo.
I think this means I'm disappointed that I can't rate and or label in PM and have those transfer to Adobe Bridge? Or is it just I don't understand. In any case I tried tagging and adding a colour class but nothing shows up in Bridge.
What's the actual intention for this new feature?
Thanks!
