On Wednesday, Apple released an updated version of iTunes to add support for 1080p video and address several issues with iTunes Match.
iTunes 10.6 adds the ability to play 1080p HD movies and TV shows from the iTunes Store, a new offering from Apple that goes along with the new Apple TV unveiled on Wednesday. iTunes could play 1080p content in the past, however, such as movies shot using an iPhone 4S.
More exciting to many iTunes Match subscribers are improvements to the music matching and storage service. Apple says iTunes 10.6 provides for improved song matching; improved album artwork handling, downloading, and display; and fixes an issue where songs may skip when playing from iCloud.
The update is currently available via Software Update, or via Apple's iTunes download page.
