In conjunction with the announcement of the iPhone 5 and new iPod models, Apple has released iTunes 10.7 to add support for iPhone, iPad, and iPod touch models running iOS 6 (scheduled for release on 19 September 2012). Additionally, it adds support for the latest iPod nano and iPod shuffle models. With no new features, iTunes 10.7 is just a compatibility stopgap until the next major release of iTunes appears in October. (Free, 157.33 MB via direct download or 163.3 MB via Software Update)
Better Text Formatting in iPhoto
If you're creating a card or book in iPhoto, and you're not happy with the formatting options for the text (such as line spacing or justification), copy the text out to TextEdit, make the changes you want there, and paste it back into iPhoto, which will retain your changes.
