[Zope] Up-to-date Zope books in print?

Hello, We're looking for some good, up-to-date Zope-books. So far it looks like the Zope Bible from 2002 is the most recent one. Does anybody know which version of Zope this book covers? Also, does anybody know if there are any commercial books that cover newer versions of Zope? Thanks, -Petter-
