Appendix B. Changes between UML Versions
When the first edition of this book appeared on the shelves, the UML was in version 1.0. Much of it appeared to have stabilized, and it was in the process of OMG recognition. Since then, there have been a number of revisions. In this appendix, I describe the significant changes that have occurred since 1.0 and how those changes affect the material in this book.
This appendix summarizes the changes so you can keep up to date if you have an earlier printing of the book. I have made changes to the book to keep up with the UML, so if you have a later printing, it describes the situation as it was as of the print date.
