According to Wu, Wu learned that according to Christine Kim’s summary of the 139th Ethereum Consensus Core Developers Meeting (ACDC), the meeting mainly discussed:

Pectra progress update (CL specification alpha.4 is about to be released; Denvet 2 is gradually stabilizing; weekly progress update meetings are added to strengthen communication between client teams; Devnet 3 will test the latest EIP 7702 design, and it is expected that EIP-7688 will be included before Devnet 5).

PeerDAS updates (discussion of necessity of "blobsidecar" API; concerns over removing sampling module to reduce complexity).

Research updates (cases where balances may not update when validators merge their staked ETH under EIP 7251; network layer adds “quic ENR entry”, auxiliary nodes send receive data).
