These features actually aren't new, but they were originally only available at certain stadiums (Braves, White Sox, Dodgers, Angels, Padres, Mariners, Rangers, and Blue Jays). It's been around since late last season, but we've just had fairly limited exposure to it. Although, it's supposed to be in all 30 team parks by the end of the season, and it appears that the Cubs have gotten it now. EDIT: Crap, I'm slow.
