iPhoto 9.1.3
Apple has released iPhoto 9.1.3. According to the release notes, the update addresses only a single problem that could cause some events merged in the company’s photo management software to be split back out into individual events after syncing to an iOS device. ($14.99 new, free update, 106.3 MB)
If you purchased iPhoto through the app store, you can get the upgrade only through the app store. Software update will not show the update, and if you download the update from Apple's download web site, you will be prevented from installing it.
Ooo, good point - we're going to have to keep that in mind going forward.
Also, if you bought it from the App Store, its actually a 727 MB update as the whole app must be downloaded again (due to the digital signature). Apple need to fix this if the App Store is going to play an ever bigger role....
