Version v0.30.1‑beta.1 introduces remote table support for PyTorch dataloaders and blob mode in query_to_pandas, while deprecating replace_field_metadata.

Why it matters: Affects Python API users; the deprecated replace_field_metadata will be removed, requiring migration to update_field_metadata before future releases.
