The main screen in the dialer was, and still is, your favorite contacts as well as the most recent call up at the top. From the comparison below you can see the layout of the favorite contacts has been tweaked quite a bit. Each one is a larger card with its own overflow button which triggers the full contact card UI. Additionally, you can long-press on each card and drag it around to rearrange the list. You'll also notice the bottom action bar is blue instead of white.
