Ethereum Glamsterdam upgrade testnet fork delayed: On November 6, the Foundation said that audit firm ChainSecurity had found that gas pricing changes in EIP-8037 and EIP-8038 could break eight assumptions relied on by existing smart contracts. Core developers decided not to proceed with the Hoodi testnet hard fork until the issues are resolved, and published a checklist for projects to review themselves. There is no mainnet activation schedule yet, while the subsequent Hegota upgrade is proceeding as planned.
