The new quest tracker was released as part of Thursday's PTR build. This is different than the one that they included last time they made an attempt in this area. Previously, they used various types of icons to tell you what type of quest was in that area. This time, they've gone with a simpler approach. Instead of using different types of icons, you simply get a numbered circle that matches up with the same number in a quest window attached to your map. If the quest objective is scattered across a larger area a little glowing overlay is put up covering that area. It also puts a question mark on the map marking your turn in location.
