prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Bound the maximum supported Python version
  Related: #462.
  
  The BigQuery library does not support Python 3.9 yet, as the `bqstorage` and `pandas` extras are blocked by the `pyarrow` dependency. Pyarrow [added](https://issues.apache.org/jira/browse/ARROW-10224) the Python 3.9 support, but the change has not been released yet (awaiting `pyarrow==3.0.0`).
  
  We need to reflect this in `setup.py`'s ``python_requires`.
