From the introduction: The purpose of this booklet is not to provide a comprehensive list of everything that has changed with the 3.5 revision. The changes are too large in number and varied in scope to be able to provide an all-inclusive inventory. Instead, what we want to do is to show you a broad picture of what has changed and to provide you with support for updating our most popular product.
