  Split out null result formatters from the error formatters and added some tests. ([#2022](https://github.com/ethereum/web3.py/issues/2022) <https://github.com/ethereum/web3.py/issues/2022>__)

• Set a default maxFeePerGas value consistent with Geth ([#2055](https://github.com/ethereum/web3.py/issues/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) <https://github.com/ethereum/web3.py/issues/2064>__)

Improved Documentation
