    Release Notes: This release reworks pj_transform() to avoid applying ellipsoid to ellipsoid transformations as a datum shift when no datum info is available. It avoids applying "change of ellipsoid" during datum shifting based on ellipsoids getting changed to spheres for spherical projections. It has been upgraded to EPSG 6.13.
