Apple has released three new firmware updates all at once. MacBook Pro SMC Firmware Update 1.5 "resolves an issue where a MacBook Pro being used with a power adapter may unexpectedly shut down under heavy workload if the battery charge level is near empty." It's not entirely clear which models of MacBook Pro are covered by this firmware update; if in doubt, check for it via Software Update.
Digital Camera RAW Compatibility Update 3.9 adds RAW image support to Aperture 3 and iPhoto '11 for 11 new camera models.
AirPort Base Station and Time Capsule Firmware Update 7.6 addresses the most issues of all the firmware updates Apple's released today.
