@ -933,7 +933,7 @@ I deeply appreciate the help of the following people.
- [bogemic](https://github.com/bogemic) fixed some C++17 deprecation warnings.
- [Eren Okka](https://github.com/erengy) fixed some MSVC warnings.
- [abolz](https://github.com/abolz) integrated the Grisu2 algorithm for proper floating-point formatting, allowing more roundtrip checks to succeed.
- [Vadim Evard](https://github.com/Pipeliner) fixed a Markdown issue in the README.
Thanks a lot for helping out! Please [let me know](mailto:mail@nlohmann.me) if I forgot someone.
