Thanks for your comments and you are correct. The book was released around January, which was pre GA release. Since then, the code base has undergone quite a few changes. This is one of the upsides (or downsides if you're trying to write a book on it) with open source. There is a discussion underway about updating the book (and the source for the book) based on the latest release. But as you imagine, even that will be old by several months when the book is released. It's a ugly cycle :)
