Well, I have not actually used the product, but it's been out since 2010 so it is highly likely that it has been reformulated sometime since its introduction. I believe you'd be hard pressed to find any coating that has not been reformulated at least once since then, as per the ever-tightening grip of the EPA on the industry.
In general, the manufacturers never (or at least very, very rarely) release any real info on the changes that take place when reformulations occur. In fact, most often they don't even tell us a reformulation occurred at all - we discover it when we work with it. You can't fool the folks who use the stuff every day, the pros see & feel the difference.
So, I cannot tell you definitively that it has been reformulated, or in what way. Pretty much the only one who could tell you this is someone who has been using it for some time & has experienced the reformulation firsthand. Or maybe a BM rep.
Sorry I don't have a better answer for you. Maybe someone else here does.
