2012 Stang 5.0 Order Guide suggests that there are changes to the powertrain?

There is a star next to the engine and transmission. Does anyone know what the changes are?

Hmmm...that's odd. The code for the Base GT and GT Prem are both 99F and only the premium has a star... I'm sure the GT and GT Prem engines would be the same. (ref page 8 and 10 of the order guide). The boss engine should be the only one different.
