Apple released iTunes 11 about two weeks ago, and now the software’s first update has been released in the Mac App Store. iTunes 11.0.1 brings back the ability to find duplicate items in a library. Apple excluded the feature in the first version of iTunes 11, but the company promised to add it back in a future update.
Besides the ability to display duplicates, Apple has included some bug fixes for iTunes Match, AirPlay and multiple stability improvements.
