On June 6, 2008, the Fourth Edition "Player's Handbook", subtitled "Arcane, Divine and Martial Heroes", was released. It was originally announced that the 4th edition's three core rulebooks would be released over a three-month period, but the date changed after customer feedback revealed a majority preference among D&D customers to have all three core rulebooks released in the same month. The Fourth Edition "Player's Handbook" was designed by Rob Heinsoo, Andy Collins, and James Wyatt. The front cover illustration was by Wayne Reynolds and the back cover illustration was by Dan Scott, with interior illustrations by Zoltan Boros & Gabor Szikszai, Matt Cavotta, Eric Deschamps, Wayne England, David Griffith, Ralph Horsley, Howard Lyon, Raven Mimura, Lee Moyer, William O'Connor, Steve Prescott, Dan Scott, Anne Stokes, Franz Vohwinkel, and Eva Widermann.
