According to Christine Kim's summary of the 205th Ethereum Execution Layer Core Developer Conference (ACDE), this meeting mainly discussed: Pectra upgrade schedule (Holesky and Sepolia testnets are scheduled for February 24 and March 5, respectively, and if the testnet goes well, it will be upgraded on the main network on April 8), Fusaka upgrade plan (to start discussions to speed up the Ethereum upgrade, TimBeiko finally decided to lock the Fusaka scope on April 10), EOF update (debate over whether EOF should be implemented with PeerDAS and whether to include Fusaka; EOF stands for EVM object format, which makes some changes to the Ethereum code execution environment), etc.
