They changed the casting and compound for the brand new tires made in 2016.
It was stated in Grassroots Motorsports Magazine, but they didn't go into much detail, other than it tests better in responsiveness, slightly more grip than the previous casting.
This years times are lower on the new casting as well, but not by much.
Sorry I can't give you much more detail.
