Any objection to merging this: ethereum/execution-apis#197
We can reiterate for getPayloadV2 long term, but I think it's better to have it not in a PR but inside a spec itself

[jessepollak]

Can we please discuss what the implementation plan is for c-kzg to come up to date with the latest specs? This is currently blocking Lodestar development and likely will block other clients as well.

The fee market PR (ethereum/EIPs#5707) is finally merged. The only substantive change there after last week's call was the agreed upon change of MIN_DATA_GASPRICE to 1. So that should be the only fee market related diff between the current spec and the latest testnet now.

I also created 3 new draft PRs:

• [EIP-4844] Set A Minimum Data Gasprice EIPs#5862 for discussion of MIN_DATA_GASPRICE
• [EIP-4844] Reduce Throughput EIPs#5863 to set the target and max blobs per block to a smaller initial value
• [EIP-4844] Return Modulus From Precompile EIPs#5864 as per last call - I didn't yet give Dankrad any time to add the rationale though

Would be good to have a few min on the call to briefly give an update on those.

Also, one thing that came up with these PRs: Because ethereum/EIPs#5649 added external links (to the consensus specs) to the EIP, the EIP as-is no longer passes all required EIP repo bot checks. As a result, auto-merge of PRs by EIP authors or with EIP author approval is broken, any PR now has to be manually merged by an EIP editor. We should agree on a way to fix this - either get the EIP editors to modify the bot, or remove the external links from the EIP.

[jessepollak]

We should also discuss the Capella upstream issue: ethereum/consensus-specs#3052

[jessepollak]

Let's also discuss the cryptography interface spec change: ethereum/consensus-specs#3038

Closed in favour of #655
