r.slope.aspect

[Allan Axon]

I calculated some slope maps from USGS 7.5' DEM's using r.slope.aspect
in GRASS 4.0.  I've recalculated the same maps using r.slope.aspect in
GRASS 4.1.2. I've gotten different results. The g.manual pages indicate
that new algorithms will be used in upcoming versions, but was there a
change in algorithms between 4.0 and 4.1?

Thanks in advance,
Allan Axon
