Also copes with missing purchases
Apple has released an iTunes 11.0.2 update for Mac and Windows users. Notes indicate that the update adds a Composers view to the software, and that the app should be more responsive when syncing large playlists. The code should also solve a glitch which prevented purchases from appearing in an iTunes library.
The Mac update should be available through the Mac App Store, while the Windows release can be downloaded using Apple Software Update. The former is 188.15MB, whereas the latter is just 85.95MB.
