4 Winds Fantasy Gaming has updated the PDF of The Book of Divine Magic. The new PDF was created from the print-ready files for the 2nd Printing (May 2011) of the book. It includes some minor changes to the interior layout, incorporates all known errata directly into the text, and includes some artwork and tables that did not make it into the 1st printing.
If you downloaded the product from Paizo or from DriveThruRPG, you should soon be able to download the updated file at no extra cost.
