Geod now uses C code adapted from geographiclib now included in proj4 source, instead of pure python code directly from geographiclib.
make radians=True work with Geod.npts (issue 47).
allow PROJ_DIR env var to control location of proj data (issue 40).
1.9.2 (svn revision 301)¶
updated proj4 src to 4.8.0 - includes two new map projections (natearth and isea).
1.9.1 (svn revision 285)¶

fixed bug in Geod class that caused erroneous error message “undefined inverse geodesic (may be an antipodal point)”.
fix __reduce__ method of Geod class so instances can be pickled.
make sure points outside projection limb are set to 1.e30 on inverse transform (if errcheck=False).
fixed small setup.py bug.
generate C source with Cython 0.9.6.6 (pycompat.h no longer needed).
1.8.2¶
added ‘srs’ (spatial reference system) instance variable to Proj.
instead of returning HUGE_VAL (usually ‘inf’) when projection not defined and errcheck=False, return 1.e30.
added Geod class for geodesic (i.e. Great Circle) computations. Includes doctests (which can be run with pyproj.test()).
proj.4 source code now included, thus removing proj.4 lib dependency. Version 4.5.0 is included, with a patch to create an API for geodesic computations.
python 2.4 compatibility patch (suggested by Andrew Straw) from M. v. Loewis: http://mail.python.org/pipermail/python-dev/2006-March/062561.html
1.8.1¶
if given tuples, returns tuples (instead of lists).
test for numpy arrays first.
Fixed error in docstring example.
README.html contains html docstrings generated by pydoc.
Renamed pyproj.so to _pyproj.so, created a new python module called pyproj.py. Moved as code as possible from _pyproj.so to pyproj.py.
docstring examples now executed by doctest when ‘pyproj.test()’ is run.
added test to _pyproj.c which defines Py_ssize_t for python < 2.5. This is necessary when pyrex 0.9.5 is used.
1.8.0¶
Better error handling Proj.__init__.
Added optional keyword ‘errcheck’ to __call__ method.
If True, an exception is raised if the transformation is invalid.
1.7.3¶
python 2.5 support.
