Apress is now able to offer its textbooks in a larger, wider format that lends itself better to textbooks and technical books with lots of graphics and code inserts. The decision was made between the authors and the Apress editorial team that it was worth pushing back the release date by a month or two, in order to allow time for our book to be reformatted for the new size. The scheduled release date is now tentatively set for early November, and the book (in its new format) is already available for preorder on Amazon.
