Backward-compatible with the 3.5 fantasy rules but offering new solutions and options that place it firmly on the cutting edge, the Pathfinder Roleplaying Game Beta features revised and updated rules for the seven classic fantasy roleplaying game races and all 11 core classes, plus a streamlined skill system, new and revised combat options, a completely overhauled experience system, and a host of new feats, equipment, domains, specialty schools, spells, curses, diseases, poisons, and much more.
