Member HAPI_GeoInfo::hasMaterialChanged: This variable is deprecated and should no longer be used. Materials are now separate from parts. They are maintained at the asset level so you only need to check if the material itself has changed via HAPI_MaterialInfo::hasChanged instead of the material on the part.
Member HAPI_ObjectInfo::geoCount: No longer used. See Geos
Member HAPI_ObjectInfo::objectInstancePathSH: This member is no longer used
