Glamsterdam Hoodi Testnet Announcement

The Glamsterdam network upgrade, activated on Sepolia on October 6, is now scheduled for the Hoodi testnet. It advances Ethereum's L1 scaling roadmap with enshrined proposer-builder separation, block-level access lists, and gas pricing changes that better reflect execution costs and state growth. The upgrade continues Ethereum's multi-testnet rollout toward mainnet deployment.
