No, you are wrong here:  We fixed a long-existing bug in height-field
smoothing that is mentioned in the release notes (iirc).  In short,
height-field smoothing did not work correctly before and thus now is looks
"different" compared to older versions of POV-Ray because those versions
were simply buggy.
