Update to 4.5.0.  Important changes since 4.4.7:

 o [bug fixes]

 o Upgraded to EPSG 6.11.1 database.

 o Fix Krovak projection (include +czech flag)

 o Added Roussilhe Stereographic projection from libproj4 (proj=rouss).

 o Added experimental +lon_wrap flag for alternate pj_transform() longitude
   wrapping behavior on output.

 o Added the proj=stereoa and proj=geos projections, incorporated from
   Gerald's libproj4.

 o Substantially change pj_datum_transform(), so it and pj_transform() will
   work between coordinate systems with different ellipsoids but no datum
   shift information (assume +towgs84=0,0,0).

 o Improved the accuracy of Geocentric_To_Geodetic() via an iterative
   solution.
