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.
EPSG was upgraded to the 6.11.1 coordinate system
database. Krovak projection was fixed up, and
Roussilhe Stereographic projection was added. The
experimental +lon_wrapp flag was added for
longitude wrapping control.
JNI (Java) wrappers were added along with stereoa and geos projections. The tools are now built against PROJ DLL on Windows by default. Various fixes were made.
