 And high church Anglicans still abide by that. But I cannot remember which bishop did it. It was during the times of the Reformation. Because the Calvinist theology denied that Mass was a sacrifice, they changed the liturgy of ordination to also deny the sacrificial nature of the priesthood. Hence, they changed it. Now, people say that about the Novus Ordo. It is not true. The Novus Ordo priests are clearly ordained to offer sacrifice.
