- Validate withdrawal fields as per EIP-4895 - Add some gut check tests for validation of withdrawal fields - Simplify empty account cleanup logic when withdrawal amount is 0
- Check for empty accounts to delete after applying all withdrawals, much in the same way we check at the end of transaction computations. - Add a test for testing withdrawal retrieval from the chaindb - Minor refactoring and fixes
- Add a deprecate method wrapper - Use this to wrap the opcode instructions for ``SELFDESTRUCT`` in the ``SHANGHAI_OPCODES`` - Add tests to make sure the deprecation warning is only listed for ``SELFDESTRUCT`` and only within the Shanghai VM
- Update ``eth-typing`` to ``3.3.0`` - Use ``ForkName.Shanghai`` value in tests
- Create a more general class method for validating the create message as a whole and bring the initcode size validation into that. This way, if other fields of the create message need validation in the future, we have a more useful method that's already abstracted and can be invoked in the proper VM computation class. - Consume the initcode cost before the computation starts for create transactions and handle initcode cost in the opcode implementations for ``CREATE`` and ``CREATE2``.
- All test vectors now applied to ``Shanghai`` rules.
- Tests that fit into the INCORRECT_UPSTREAM_TESTS in ``test_blockchain.py`` - Tests that time out

What was wrong?
Shanghai fork support needed:
How was it fixed?
Notes:
- The
fixturessubmodule (ethereum/tests) was updated to the latestv12.- There are many Shanghai
ethereum/testsrelated to EOF even though this was kicked down the line to theCancunhard fork. I've turned these off for now with a TODO to turn these back on once EOF is implemented. Currently, all other Shanghai-related tests are passing.Todo:
