Just released a new version of TOML Fortran and its JSON frontend: [TOML Fortran 0.4.0 released — TOML Fortran](https://toml-f.readthedocs.io/en/latest/news/2023-04-release-0.4.0/).

There are mainly improvements to the serialization of data structures, hiding the original `toml_serializer` class behind convenience interfaces `toml_dump` for files and units and `toml_dumps` for strings. Also, the internal storage structure and the exposed type-bound procedures in the data structures have been adjusted to make renaming or removing of substructures easier. Finally, serialization functionality is available in the [JSON frontend](https://toml-f.readthedocs.io/en/latest/how-to/jonquil/) providing now all the same features available for TOML also for JSON.

Note, I’m still looking for support with maintaining TOML Fortran: [Looking for (co-)maintainers · Issue #62 · toml-f/toml-f · GitHub](https://github.com/toml-f/toml-f/issues/62). Feedback and contributions are always welcome.
