As Scott already posted, iLife '08 just released a slew of updates. Although Software Update says that over performance and general compatibility issues were addressed in most products, the biggest change is MobileMe support for all iLife '08 applications.
iPhoto, iWeb and iMovie are now properly linked with the MobileMe service. This should be welcome news to iWeb customers who have been unable to maintain or update elements of their MobileMe (nee .Mac) pages since the transition earlier this month.
Likewise, galleries and movie can now be published directly to the newly branded mobile offering. You know, assuming you can get the service to work.
