According to reports by Wu, the key discussions at the 146th Ethereum Core Developers Meeting (ACDC), summarized by @ralexstokes, focused on the final confirmation of the Pectra specifications.

The updated EIP-7691 proposal targets blob throughput adjustments, setting a goal of 6 and a maximum of 9, to improve L2 transaction throughput and reduce costs.

The EIP-7742 proposal involves fee standardization, deciding to adopt a simplified scheme and updating the 'update denominator' of the base fee to reflect a higher blob count.

The EIP-7251 proposal updates the merging mechanism, simplifies state transitions, and addresses validator authorization issues, with plans for further merges.

The FOCIL design demonstrates ensuring effective inclusion lists through a forced selection algorithm.

Other updates include bug fixes for the Mekong testnet and ongoing development of the Devnet-5 specifications.
