Apple has released iTunes 11.3 for Mac OS X and Window. The update adds support for iTunes Extras in HD movies. With iTunes Extras, viewers can see cast interviews, exclusive clips, behind-the-scenes footage, and photo galleries along with a movie.

HD movie extras are available on the Apple TV set-top box for those who’ve updated it with Software Update 6.2. HD movie extras support will come to the iPhone, iPad, and iPod touch when iOS 8 is released this fall.

iTunes is free and available for download at the Mac App Store. The 11.3 update can be installed via the OS X System Preference’s Software Update app.
