Solves matching, artwork problems
To go along with iOS 5.1 and the third-generation iPad, Apple has released iTunes 10.6. The software's main addition is support for 1080p video, which is now sold on the iTunes Store, and can be recorded by both the new iPad and the iPhone 4S. Apple TV owners can view 1080p content.
Otherwise the update deals primarily with glitches in iTunes Match. The matching process has been improved, and it can now cope better with album artwork, including display and downloads. Apple has also addressed a problem with iCloud streaming in which songs would skip.
Mac and Windows versions of the update are available, the latter in 32- and 64-bit editions.

Did they fix the multiple user account issue? If you have two separate users on one computer iTunes matches locks one user out for 90 days. Or does apple think we all have 80 billion to by separate machines?
