Apple has released AirPort Utility 5.3.1 for Mac OS X 10.4 Tiger, 10.5 Leopard and Windows Vista. Previously only available on the software CD with the Time Capsule, this utility is freely download-able as well as being available in Software Update. Notably, it has the ability to install a program that runs in the background and can monitor your Airport Extreme or Time Capsule for when extra USB drives are connected on the local network, as well as check for software and firmware updates. It also makes it easy to roll back a base station to earlier firmware if an update causes problems.
One of the more useful features added, however, is the ability to set the Bonjour name of a base station. If you aren't already aware, Bonjour is the network service that allows devices to automatically discover each other and connect. Being able to set the name allows you to set what people see the name as in their Leopard side-bar and Network view.
