In a move that should surprise no one, Apple has released a new version of iTunes in the wake of this afternoon’s unveiling of the new iPad and the new Apple TV. iTunes 10.6 now supports 1080p video from the iTunes Store. It also includes a few security tweaks, some performance updates for iCloud, improved performance for iTunes Match, and improvements to the way iTunes downloads and displays album artwork.

As always, iTunes 10.6 is available as a free download from Apple’s website. Mac users can also get the update by running Software Update. The new iPad and the new Apple TV are both available for pre-order from the Apple Store. You can pre-order now for delivery on March 16th (which is also when they are available in stores). The Apple TV is $99, and the new iPad starts at $499.
