Bugfixes
~~~~~~~~

- If a transaction hash was passed as a string rather than a HexByte to ``w3.eth.wait_for_transaction_receipt``, and the time was exhausted before the transaction is in the chain, the error being raised was a TypeError instead of the correct TimeExhausted error. This is because the ``to_hex`` method in the TimeExhausted error message expects a primitive as the first argument, and a string doesn't qualify as a primitive. Fixed by converting the transaction_hash to HexBytes instead. (`2068 <https://github.com/ethereum/web3.py/issues/2068>`__)
- Hot fix for a string interpolation issue in message when BadFunctionCallOutput is raised for call_contract_function() (`2069 <https://github.com/ethereum/web3.py/issues/2069>`__)
- ``fill_transaction_defaults()`` no longer sets a default ``gasPrice`` if 1559 fees are present in the transaction parameters. This fixes sign-and-send middleware issues with 1559 fees. (`2092 <https://github.com/ethereum/web3.py/issues/2092>`__)


Improved Documentation
~~~~~~~~~~~~~~~~~~~~~~

- Added troubleshooting section for Microsoft Visual C++ error on Windows machines (`2077 <https://github.com/ethereum/web3.py/issues/2077>`__)
