Changes between 2.5 (released 2024-12-28) and 2.4 versions: * New magnetic models provided + World Magnetic Model 2025, wmm2025; this covers the period 2025-2030. This is now the model returned by MagneticModel::DefaultMagneticName and is default magnetic model for MagneticField (replacing wmm2020 which is only valid thru the end of 2024). + World Magnetic Model High Resolution 2025, wmmhr2025; this is a high-resolution version of wmm2025 including terms up to degree 133 (as opposed to 12 for wmm2025). + International Geomagnetic Reference Field (14th generation), igrf14, which approximates the main magnetic field of the earth for the period 1900-2030. * Update CMake's cmake_minimum_required to 3.17.0 (to facilitate integration with Qt projects). * For GEOGRAPHICLIB_PRECISION > 2, readarray treats doubles as approximations to exact decimal constants. -- Charles Karney <ka...@al...> 702 Prospect Ave Princeton, NJ 08540-4037 |
