Apple slipped out Pro Applications Update 2008-004 late Thursday night. The update for the Final Cut Studio 2 app suite includes Final Cut Pro 6.0.5, Compressor 3.0.5, Color 1.0.3 and Shake 4.1.1, and the terse release notes simply state that it "addresses general performance issues and improves overall stability." The update is free and available via Appleis Software Update application.
