AI summary of the source article
Ethereum's Glamsterdam upgrade successfully activated on the Sepolia testnet on 6 October at epoch 353,024, maintaining normal two-epoch finality post-fork. The release includes 18 Ethereum Improvement Proposals, led by EIP-7732, which introduces enshrined proposer-builder separation to reduce reliance on trusted middleware and introduces a new payload timeliness committee. Other notable inclusions are EIP-7928 for parallel transaction validation and EIP-8037 for gas repricing. Node operators and stakers must update both execution and consensus clients. The Ethereum Foundation confirmed that activation dates for the Hoodi testnet and mainnet remain undecided.
