[Geographiclib-announce] GeographicLib 2.3 (released 2023-07-25)

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

Changes between 2.3 (released 2023-07-25) and 2.2 versions:

    * Add the Intersect class and the IntersectTool utility.  The
      methods are described in "Geodesic intersections",
      https://arxiv.org/abs/yymm.nnnn (to appear 2023-08).

    * Add typedefs Geodesic::LineClass, GeodesicExact::LineClass,
      Rhumb::LineClass, GeodesicLine::BaseClass,
      GeodesicLineExact::BaseClass, RhumbLine::BaseClass.

    * Geodesic constructor accepts optional third argument exact, default
      false.  If true, then the calculations are delegated to
      GeodesicExact.  GeodSolve and Planimeter now use this simplified
      interface.

    * PolygonAreaExact is deprecated; use PolygonArea instead.

    * Bug in Planimeter -Q (introduced in version 2.2) has been fixed.

    * TransverseMercator constructor accepts optional arguments exact
      and extendp (default false for both).  If exact = true, then the
      calculations are delegated to TransverseMercatorExact.
      TransverseMercatorProj now uses this simplified interface.

    * Minor fixes:
      + Fix documentation bug for TransverseMercatorProj (incorrectly
        stated that -t for the extended domain was the default).
      + Remove unnecessary friend declarations for Ellipsoid in
        AlbersEqualArea and TransverseMercator. (As of version 2.2,
        Ellipsoid uses the AuxLatitude class for this functionality.)
      + Small change in EllipticFunction to speed up the default
        contructor.
      + Remove workaround for boost 1.76 with enums (not needed for boost
        1.78).
      + Remove unused header from NearestNeighbor.
