According to the Gross link, the main change was letting the linesmen use more discretion...so that now, apparently, what would have been an icing call before is now being called as an errant pass and waved off.
But at any rate, you're right - no one's complaining. Certainly not me; I used to HATE icing calls, since there always seemed to be so damned many of them, and they always seemed like such a useless stoppage of play.
