Are you using the Sybex "Official Study Guide" written by Mike Chapple and others? if so, the 10th edition is the latest. If, on the other hand, you're using the "CISSP Official Textbook, 7th Edition", then you're using something from ISC2's official courseware, and the 7th ed is the latest AFAIK. What does the front cover look like? This?
