Apple on Thursday released an updated version of its iTunes software following a series of announcements made during the company’s press conference in New York City. The Cupertino, California-based firm unveiled its new interactive iPad textbook product alongside iBooks 2 Thursday morning, and it also took the wraps off of an updated iTunes U service that includes new tools for teachers and a new iPad app. To accommodate Apple’s new features, the company also pushed out iTunes 10.5.3, which is available for download immediately. Apple’s official change log follows below.
