Technically, the requirement to do some form of penance every Friday is still in force, only none of the V2 bishops care. My kids and I still do meatless Fridays all year, because that's as good a form of penance as anything else.
Notable Exceptions: Friday after Easter and the Friday after Thanksgiving (Pius XII gave Americans a special indult so they could eat up their leftover turkey).
