Apple on Wednesday released version 11.0.4 of iTunes.

The iTunes update, which follows 10.8.4 of OS X Mountain Lion from yesterday and comes a week before Apple's World Wide Developers Conference, is now available through Software Update on the Mac App Store and notably fixes a bug that required users to repeatedly log into the iTunes Store.

The latest version of iTunes also fixed an iOS device syncing bug that sometimes occurred when moving between wireless and wired, and it re-included album artwork, which previously disappeared in version 11.0, thanks to an improved Songs view and Apple's MiniPlayer with a new built-in progress bar. The change log also noted an update where multi-disc albums now appear as a single album. 

Version 11.0.4 weighs 187.52MB on the Mac, but an update for Windows 64 is also available
