Ethereum's 220th All Core Developers Execution (ACDE) meeting focused on Fusaka Devnets, revealing low network participation at around 50% during the second round of non-finality testing on Devnet-3. The issue appears linked to the Engine API methods rather than Fusaka's features, with Geth developers working on a fix. Devnet-5 has been launched for BPO fork analysis. The Fusaka timeline was also discussed, with plans to set the public testnet upgrade block height on September 18, upgrade the Holesky testnet on September 29, Sepolia on October 13, and Hoodi on October 27. The mainnet activation date will be determined after public testnet upgrades progress. Additionally, discussions on five small EIPs related to Glamsterdam were held, though no decisions were made.
