JSON for Modern C++ 3.9.0 is a feature release that adds four long-awaited features, some requested five years ago.

The parser functions have now an option to ignore // and /* */ style comments. Though comments are not officially part of the JSON specification, comment support was a frequently requested feature, and its implementation was much less effort than continuously explaining the lack of comment support.

The second-most requested feature was a way to preserve the insertion order of object keys. Though this was possible via template specialization for a while, we now added a new type nlohmann::ordered_json as drop-in replacement for nlohmann::json for this.

To circumvent unexpected behavior, implicit conversions can now be switched off with a CMake or preprocessor option.

Last, but not least, a mapping between user-defined types and JSON can now be expressed using convenience macros by just listing the names of the member variables to read/write.

All changes are backward-compatible. See below the complete list of changes.
