Ethereum core developers convened for the 219th Executive Core Developers Meeting, focusing on the Fusaka development network's progress. Devnet-3 is expected to conclude today, with the consensus layer team addressing synchronization issues. A subsequent non-final test is planned for next week, with devnet-5 to follow if successful. The meeting also covered the planned retirement of Holesky, with Fusaka set to abandon it weeks after activation. A public post will outline the timeline and migration guidance. Additionally, developers aim to increase the Gas Limit to 60 million before the Fusaka upgrade, and future meetings will prioritize discussing PFI issues as requested by clients.
