iTunes 10.1 has just become available for download.

iTunes 10.1 allows owners of Airplay-supported devices, including the iPad, iPhone and Apple TV, to instantly and wirelessly stream videos from iTunes. The update also supplies the usual round of stability and performance improvements.

The release of iTunes 10.1 also means that the iPad is now ready for the iOS 4.2 update, which will bring a new multitasking bar that has both volume and brightness controls, as well as a dedicated AirPlay button, to the device.

Notably, AirPrint, which allows device owners to print wirelessly over Wi-Fi without having to install any drivers or additional software, will not be included in the iOS 4.2 update for iPad as expected.
