Unfortunately I do--I had to take a stupid seminar on the thing. They've basically enhanced some definitions of "exempt" vs. "non-exempt" employees, which were evidently too ambiguous. A "non-exempt" employee is who qualifies for overtime, and they have to spend a certain percentage of their time performing non-exempt duties. They tried to clarify some of the confusion re. what exactly a non-exempt employee is, & I have to admit I was pretty surprised at who qualifies as non-exempt.
There are some other changes too, but it's way too complicated to explain here. Your employer's attorney should be able to give you the details.
