 From the ChangeLog, v2.0.0:

     o Removed arrow operator (->) for iterator returned by Fields,
       Result and Row containers.  It was inherently buggy, because
       a correct arrow operator must return the address of an
       object, but the underlying element access functions in these
       classes (e.g. at()) return objects by value, of necessity.
       Therefore, this operator could only return the address of
       a temporary, which cannot be safely dereferenced.
