They're calling it Dirty Dozen Plus to especially highlight green beans and leafy greens like kale and collard greens. While these veggies don't meet traditional Dirty Dozen criteria, the EWG says they are often contaminated with highly toxic organophosphate insecticides, and so should be purchased organic whenever possible.
As usual, the guide also contains a list of the Clean 15, the produce lowest in pesticides and therefore safe to buy conventional.
