Glamsterdam upgrade on Hoodi testnet postponed pending EIP-8037 investigation

The Glamsterdam upgrade on the Hoodi testnet, originally scheduled for October 26, 2026 at 17:42:48 UTC, has been postponed with no new activation date set. Core developers decided on ACDE #248 to delay the upgrade to allow further investigation into the interactions of EIP-8037 with mainnet smart contracts, which removes the scheduled Amsterdam execution layer activation, Gloas consensus layer activation, and the gas-limit increase to 200M. Node and validator operators must update their software configurations to reflect the postponement and await a separate announcement for the revised schedule; this only affects the Hoodi testnet, not the Ethereum mainnet.
