Changes in version 0.4-0 (2019-12-05)                  

  - Change to which WKB representations SpatialPolygons convert to
      - SpatialPolygons objects now convert to either WKB Polygons or
        WKB MultiPolygons
          - If each Polygons object in the SpatialPolygons object
            contains a single Polygon object with only one exterior
            boundary then convert to WKB Polygon, otherwise convert to
            WKB MultiPolygon
          - Previously SpatialPolygons were converted to WKB Polygon
            containing multiple rings
