Apple has issued a minor bug fix update to both AirPort Utility on OS X and on iOS. The OS X Update is available via Software Update on the Mac App Store, while the iOS version is in the App Store on iOS and iTunes.
The update, on both platforms, is to squash a bug for AirPort Base Stations not begin recognized by the app. Apple, last month, pushed out AirPort Utility updates to add compatibility for the new 802.11ac AirPort Extreme and AirPort Time Capsules.
In OS X Mavericks-specific news, Apple has pushed out an update to testers for the OS X Recovery function. Thanks, D!
