Yes. Somewhere (I don't remember where, specifically), WotC released a statement that when individual articles from Dragon or Dungeon were collected into a single PDF at the end of the month there might be changes, which wouldn't be officially noted as errata but should be considered to be so and were the official version of the rule element, etc.
