- Set a default maxFeePerGas value consistent with Geth (`2055 <https://github.com/ethereum/web3.py/issues/2055>`__)
- Fix bug in geth PoA middleware where a ``None`` response should throw a ``BlockNotFound`` error, but was instead throwing an ``AttributeError`` (`2064 <https://github.com/ethereum/web3.py/issues/2064>`__)
