If you own one of the new Santa Rosa based MacBook Pros, then head on over to the Apple website to download Software Update 1.0, which should also appear when you use the OS X Software Update app. Not a lot of details on the website, other than it provides important bug fixes and is recommended for all 2.2/2.4GHz MacBook Pro models. The update requires Mac OS X 10.4.9 or later.
