Q: Beginning WordPress 3 was written for 3.0. Does that mean it’s outdated?

A: Nope! The book is not very outdated at all, which is why we haven’t done a new edition. I got lucky, and both 3.1 and 3.2 were relatively minor releases. I’ve just updated the Updates and Errata page for the book to include a quick rundown of what’s changed since 3.0. If you haven’t gotten a copy yet, you totally should!
