well there are a lot of changes:
study browser:
there are two more tables (which one can open/close and resize), one is a patient level panel and the other is a thumbnail preview panel
viewer:
new annotation "round ROI" and also new "modify" and "delete" tool to change annotations position/size
Series thumbnail popup for easy navigation between different series/studies (right click over a thumbnail image in the thumbnail bar at the top)
burn dialog:
DVD creation is now possible. The new internal library allows CD/DVD creation without the windows XP service IMAPI
Import:
Support for Jpeg2000 compressed DICOM images
Server:
now multithreaded. Max. 10 simultaneous associations supported
Stability:
revised memory management. Stability should be improved.
