One of the nicest innovations is something that used to drive me nuts with the Woodstock jig. On the Woodstock jig you have two stops on each side of the jig that must be adjusted just right in order to prevent misalignment when you assemble your joints. Rockler has added a simple one piece stop on each side that is always square and which is preset for the correct offset. That makes it almost impossible to mis-align your boards. Very slick and Rockler even has a patent pending on this innovation.

One new innovation is a slick little duct collection chute which attaches to their jig for a much cleaner shop.
