Obviously, these lists aren't comprehensive: I have commit to Rails, am helping to write a book on Rails 4 [1], and it's not listed, either. ;) AWDWR is actually tested as part of each release,[2] so it obviously gets a big shout-out.
It's a little farther behind the others, Ryan had updated it for Rails 3.2, and I'm updating it for 4, and my editor and I are going over the first half of the book's updates now. AWDWR is already 100% updated (and I think CRA is too), so it makes sense that mine didn't get mentioned; it's hard to both work on Rails and work on writing a book on Rails.
