Apple has released an update to its AirPort Utility app for the Mac, bringing it up to version 6.3. It adds the ability to extend a guest Wi-Fi network across multiple AirPort base stations, support for WPS-capable printers, and improved international support. It's a free download, as always.
The 6.3 update requires an Intel-based Mac running 10.7.5 or later. You can grab it right now through Software Update, or head on over to Apple's update site.Apple releases AirPort Utility 6.3 for Mac originally appear
