While it has been nice to get started with, Streamlit app generation is no longer part of OneCode. See onecode-streamlit for more information on backward-compatibility.
pyarrow no longer a direct dependency of onecode. As a consequence, CsvReader element no longer read CSV through pyarrow.read_csv() but pandas.read_csv()
pydantic no longer a strong dependency, it was moved to the developer dependencies. Therefore using the variable ONECODE_DO_TYPECHECK=1 requires the pydantic installation.
