As many of you know—Apple was busy today. Along with all the other craziness they've released an update for iTunes.
In addition to stability updates and performance improvements, they've added a neat "MiniStore" that allows you to browse the iTunes store while in your own library. A great way to find new music.
iTunes 6.0.2 is a free download for Windows and OS X.
