Apple has released iTunes 11.3, bringing some improvements to iTunes Extras for HD movies. This biggest change is that you will no longer need to download iTunes Extras to your computer before using them. Along with the changes in iTunes, iTunes Extras are now available for the Apple TV. The lack of iTunes Extras support for Apple TV has been a sore spot for years, so it's great to finally see them making the jump out of iTunes. Additionally, when iOS 8 is released in the fall, iTunes Extras for movies will be supported on your mobile device too.
