Are these books outdated?

As one of the authors of this book, I can say decisively that there is
absolutely no plans at this point in time to update the book to a fourth
edition.  I don't know why they keep putting this updated edition on the
web site, it's not fair to readers to promise them something that is not
being worked on at all.

So don't count on this at all, sorry.
