Running Reth on BSC testnet? Some Jenner-related compatibility changes apply as soon as you upgrade, before the hard fork activates on Oct 28.
If your tooling supplies blockOverrides.prevRandao, review the new millisecond-remainder requirement for:
๐ธ eth_call and eth_estimateGas
๐ธ debug_traceCall and eth_simulateV1
Check affected calls, simulations, and test scripts as part of your upgrade preparation.
