Path of War

I seem to remember the general "discipline weapon only" restriction being removed from Broken Blade maneuvers during the beta, and only being applied on a case by case basis. The rule was replaced with a bonus for using discipline weapons instead. However, on both the SRD, and my PDF of Path of War, the Broken Blade section specifically says that the maneuvers can only be initiated with discipline weapons. Am I misremembering? Is my copy of the pdf outdated? Was there an errata I missed? I got my PDF through Drivethru RPG, if that helps.
