To quote the press release:
The long-awaited version 2.34 of Photo Organizer is finally here. Nearly every facet of Photo Organizer has been enhanced in some way. The most visible improvement is the refactored UI that makes extensive use of CSS and supports multiple languages. Working with larger sets of images and especially clients is also considerably simpler, with the ability to tie folders and clients to datebook events. There are also many behind-the-scenes changes to improve reliability, facilitate future scalability and of course, a massive pile of little features and tweaks.
