That site is owned by MLB so no the Brewers didn't change it. It was a change on all of the team sites on mlb.com as they all follow the same template. Try Twins.com, Braves.com, Yankees.com or Dodgers.com and you will see they all look exactly the same. MLB made an update to their templates and the standings are now removed from the front page and will probably return closer to the playoff run.
