Old rules stay the same with the difference that now you can
1) Split any two cards ( Before splitting 4's,5's or 10's wasn't allowed)
2) Double down on any two cards ( Before only 9-11 was allowed)
Overall this gives better chances to the player. On the other side most players seem to completely throw away the advantage by doubling on 8 against 6 and other silly hits etc.
House edge under old rules: 0.57016% (6 decks)
Houge edge under new rules: 0.47406%
Good news
