Apple on Thursday issued what it calls "supplemental updates" patches for different bugs in OS X 10.7.5 and 10.8.2 (each the latest version of their respective OS versions), along with an update for drivers for various lines of printers, presumably to add or restore AirPrint compatibility for iOS 6 devices, Mountain Lion compatibility and more to a long list of existing models as well as any new. Why Apple chose to call the OS patches "Supplemental Updates" rather than issue an incremental update is unexplained, but each of the two updates is version-specific.
