Upcoming iTunes 11 Update to Restore Duplicate Search, Fix Album Art and Movie Streaming Bugs
A feature that finds duplicate entries is missing. Apple says it will soon be restored in a minor update of the program.Mossberg also reports that Apple has no intention of bringing back the Cover Flow view of album art, with the company finding that few users were interested in it and the new Expanded View offering a fresh take on integrating large album art into library browsing.
In my tests, some album covers were missing in album view. Apple says this is a rare bug, but one it has solved and will fix in a minor update soon. Another bug the company says will be remedied prevents owners of Apple TVs from wirelessly streaming cloud-based movies to their TVs.
