[Geographiclib-announce] GeographicLib 1.48 (released 2017-04-09)

[Charles K. <cha...@sr...>]

Changes between 1.48 (released 2017-04-09) and 1.47 versions:

   * The "official" URL for GeographicLib is now
     https://geographiclib.sourceforge.io (instead of
     http://geographiclib.sourceforge.net).

   * The default range for longitude and azimuth is now (-180d, 180d],
     instead of [-180d, 180d).  This was already the case for the C++
     library; now the change has been made to the other implementations
     (C, Fortran, Java, JavaScript, Python, MATLAB, and Maxima).

   * Changes to NearestNeighbor:
     + fix BUG in reading a NearestNeighbor object from a stream which
       sometimes incorrectly caused a "Bad index" exception to be thrown;
     + add operator<<, operator>>, swap,
       std::swap(NearestNeighbor&, NearestNeighbor&);

   * Additions to the documentation:
     + add documentation on finding nearest neighbors;
     + normal gravity documentation is now on its own page and now has an
       illustrative figure;
     + document the truncation error in the series for auxiliary
       latitudes.

   * Fix BUGS in MATLAB function geodreckon with mixed scalar and array
     arguments.

   * Workaround bug in math.fmod for Python 2.7 on 32-bit Windows
     machines.

   * Changes in cmake support:
     + add USE_BOOST_FOR_EXAMPLES option (default OFF), if ON search for
       Boost libraries for building examples;
     + add APPLE_MULTIPLE_ARCHITECTURES option (default OFF), if ON build
       for both i386 and x86_64 on Mac OS X systems;
     + don't add flag for C++11 for g++ 6.0 (since it's not needed).

   * Fix compiler warnings with Visual Studio 2017 and for the C library.
