The most notable changes:
- It uses less memory. This matters if your iPhoto library is huge, because you will no longer overwhelm your Mac’s memory when exporting the photos to folders. It now uses a SAX parser so it no longer has to load the entire iPhoto XML file into memory.
- It shows better progress than before, telling you how many events/albums it has processed so far and how many there are total.
- If you want, it can copy photo metadata (image name, description, keywords, faces, and rating) into the exported photos.
