[Geographiclib-announce] GeographicLib 2.4 (released 2023-07-14)

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

Changes between 2.4 (released 2024-07-14) and 2.3 versions:

    * Math::sind, Math::sincosd, etc., now return accurate results for
      arguments = 30d, 45d, 60d, ...

    * Add Math::hypot3.

    * Add EllipticFunction::am.

    * Make constructor for AuxAngle explicit.

    * Include notes for plate carree areas.

    * C++14 compliant compiler required (this requirement tracks the
      Boost Math library).

    * CMake configuration changes
      + update cmake_minimum_required to 3.16.0.
      + exclude the tools and doc targets from the default build (make
        all) if these components won't be installed (BINDIR or DOCDIR
        set to OFF).
      + testprograms is now excluded from the default build and it now
        depends on tools.  Before running the test suite, build
        testprograms, e.g., make testprograms test.
      + added a target libs to build only the static and/or shared
        libraries.
      + document the use of CMake's FetchContent as an alternative to
        find_package.
      + stop requiring that CMAKE_CROSSCOMPILING match with
        find_package(GeographicLib).

    * Internal code changes
      + stop using reserved identifiers (_N in the DST class and _R in
        the Intersect class).
      + remove the workaround for the boost-quadmath bug with
        setprecision(0).
      + GEOGRAPHICLIB_PANIC(msg) macro now takes a message argument.
