The version 1.0 examples match exactly what you see in the book. Versions newer have some slight differences, generally just small cleanups and the standarization of output.
If you have any problems comments or suggestions, please leave a comment on the understandingajax.net post on my blog.
You can also contact me by email, but open forums where everyone can see the question and answer are prefered.
My blog contains more details about the book.
