I have a few questions now: =E2=80=A2 is there an overview of what release of parquet-format is current= ly fully support in parquet-cpp (something like a feature support matrix)? =E2=80=A2 how fast are new features in parquet-format adopted? I think having a document describing the current completeness of implementa= tion of the spec would be very helpful for users of the parquet-cpp library= .
