iTunes 10.1 has been released with  iOS 4.2 support and AirPlay. The update is for both operating systems, Mac and Windows.  It can now support the iOS 4.2 software for Apple’s mobile devices (iPhone, iPod Touch and iPad). The main advantage that iOS 4.2 support brings is the ability to stream music, videos and photos to Apple TV.

Other than iOS 4.2 support, there are little updates and fixes to stability bugs and performance bugs.
