iMovie users have been issued a new update, that Apple says offers "improved performance and stability". In-depth information regarding specific changes is unavailable. The upgrade also requires users upgrade to QuickTime 6.1 or higher.

The 1.9MB download is available both through OS X's Software Update and for download from the Apple's Web site.

Apple has also released AirPort 4.0.8 Firmware Update for the Snow dual-Ethernet AirPort Base Station. This update is not for Graphite or Extreme Base Stations.

The update fixes an incompatibility affecting some US customers, who find themselves unable to maintain connections using telecom provider BellSouth's DSL or dial-up services. It also helps Swedish users of services from ISP Telia.

This update requires Mac OS X 10.1.5.
