So previously this destructor was not marked virtual.  Is this a change in
behavior, or was the compiler automatically marking it virtual?

No change in behavior. The destructor was already implicitly virtual as the
parent class has a virtual destructor. I choose to make it explicitly virtual
for clarity.

 
     virtual void doApply() OVERRIDE;
     virtual void doUnapply() OVERRIDE;
