Ethereum's 222nd Core Developers' Executive meeting centered on the upcoming Glamsterdam upgrade, following the Fusaka upgrade scheduled for October 14th. Developers have initiated a shadow fork of the Sepolia testnet to prepare for Fusaka. Key proposals for Glamsterdam include block-level access lists (EIP 7928), gas pricing reform with a storage tax mechanism (EIP 8032), and new opcodes (EIP 7791) for direct gas-to-ETH conversion. The deadline for Glamsterdam proposals is set for one week after Fusaka's mainnet launch. Additionally, the Holesky testnet will be deprecated by the end of October.
