New software for the Zune for both the desktop and the device was released today.

You can download it, but the Zune desktop software should do that for you. Anyway, it looks like some new features are managing your Zune identity and a new search box on the desktop.

And on the device, there's games, a clock, tagging a song you hear using the FM radio  as well as... purchasing media wirelessly! Awesome. Now if only I could get the wireless to work on my Zune...
