* Diagnostic byte positions: A new macro,
JSON_DIAGNOSTIC_POSITIONS, introduces member functions to query
the byte positions of values in the input they were parsed from.
* Enhanced conversion macros: The conversion macros for arbitrary
types now include several upgrades: All macros are templated,
supporting json, ordered_json, and any other basic_json
specialization.
* Derived classes can now be seamlessly converted to/from JSON
using the new NLOHMANN_DEFINE_DERIVED_TYPE_* macros.
* Support for std::optional: The library now supports conversions
from/to std::optional types when compiled with C++17.
* Flexible string compatibility: Functions patch, diff, and
flatten now work with arbitrary string types.
* Binary format enhancements: The BJData mapping now supports
draft 3, including optimized binary array types. The BSON
mapping has added support for unsigned 64-bit integers. The
get_number function used in the binary format implementations
has been optimized to read multiple bytes at once.
* Multidimensional array conversion: Multidimensional C-style
arrays can now be directly converted to JSON.
* Filesystem paths in UTF-8: The conversions from/to
std::filesystem::path are now encoded to UTF-8 strings by
default on all operating systems.
* CMake 4.0 support.
