4.4.8 Release Notes
-------------------

 o Updated epsg file to EPSG 6.5, added other.extra pseudo-EPSG WMS definitions

 o Made significant fixes to prime meridian support. 
 
 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 Added pj_get_release() function.

 o Ensure pj_transform() will try to transform all points in provided list if 
   even some might transform properly.  

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

 o Various other bug fixes. 


4.4.7 Release Notes
-------------------

 o Added NTv2 (.gsb) grid shift file support.  

 o Modified datum shift support so that data file data is only loaded if
   needed.  Also added 'null' grid as a fallback option, and support for 
   making grids optional (prefix with '@' in +nadgrids). 

 o Regenerated nad/epsg file with towgs84 parameters for non-greenwich prime 
   meridians.

 o Updated nad/esri file with better generated form from Paul Ramsey.

 o Various bug fixes. 


4.4.6 Release Notes
-------------------

 o Incorporated new lcca (Lambert Conformal Conic Alternate) projection from
   Gerald.

 o Updated 'espg' translation file for EPSG 6.2.2 with better support for
   prime meridians. 

 o Added Prime Meridians via +pm command switch to cs2cs (and pj_transform).

 o Fixed bug with 7 parameter transforms. 

 o Added 'esri' pseudo-epsg coordinate system file. 

 o Cleanup so that PROJ.4 compiles clean as C++ code.

 o Added pj_get_def() to expand definitions of stuff like +init clauses.

 o Added a Krovak implementation (proj=krov).  Note this may change again
   in the next release.
