Books/documentation for Blender3D 2.40

Blender 2.40 came out and there is so many new features… I haven’t used Blender3D yet, but I would like to try new version of it. Is there any book/DVD/documentation on 2.40 version available already? If not, when approximately it is going to happen?

Obviously there is no book, but check at the wikibook and search for tuts on the forum (there’s a good one in finished projects about the new hair), and of course, the good 'ol blender.org site. There are also video tuts around somewhere.
