Apple has posted Tunes 11.0.4, a free download at the Mac App Store. It requires Mac OS X 10.6.8 or higher (a Windows version is also available). According to Apple, this version of iTunes comes with several new features and improvements, including:

° A new MiniPlayer. MiniPlayer now includes a new view that showcases your album artwork. In addition, a progress bar is now built right into MiniPlayer.

° An improved Songs View. You can now enjoy your album artwork while in Songs view.

° Multi-Disc Albums. Albums with multiple discs now appear as a single album.
iTunes 11.0.4 also fixes a problem that may cause iTunes to quit if you switch between wired and wireless syncing and addresses an issue that may require you to log into the iTunes Store repeatedly.
