Apple on Wednesday unveiled Airport Utility 5.3.2 for Leopard, Tiger, and Windows users, offering enhancements for users with an Airport Express or Extreme Base Station, or Time Capsule. As with most recent Apple updates, details are scarce. Since the update is a minor version release, it most likely contains bug fixes, operational optimizations, slightly improved features, and similar tweaks.
The updates are available from Apple's support web site, or through Software Update, under the Apple menu.
