Both implemented in Besu
- Edgar | ethrex
same in ethrex

What did we change in the spec?
- Eitan Seri-Levi
the should build on full thing
- Nico Flaig
- Justin Traglia
I would like for these to be merged before making the alpha.9 release btw: * https://github.com/ethereum/consensus-specs/pull/5306: Apply proposer boost if dependent roots match * https://github.com/ethereum/consensus-specs/pull/5309: Limit should_build_on_full checks to the previous slot * https://github.com/ethereum/consensus-specs/pull/5310: Use should_build_on_full for bid parent block hash * https://github.com/ethereum/consensus-specs/pull/5174: Remove should_override_forkchoice_update And if we decide to include it: * https://github.com/ethereum/consensus-specs/pull/5115: Exclude slashed validators from proposing (EIP-8045)
- Eitan Seri-Levi
We had a bug where our node couldn’t restart under certain conditions
- Nico Flaig
what about https://github.com/ethereum/consensus-specs/pull/5210 ?
- Justin Traglia
Replying to "what about https://g..." Oh yeah, that would be good to include too
- Nico Flaig
5115 has no consensus yet though?
- spencer
Silence = yes?
- Eitan Seri-Levi
It’s not a huge lift for us but would delay our devnet readiness by a bit
- marc | wolovim
Potuz in #interop channel: "I don't think I will be able to make it to ACDT so I'll leave my vote here to include 8045 in devnet 5”

8045 doesn't matter

- danceratopz
---------- Spec Changes: 7928 state-access decoupling ---------- 🧩 EIP-7928 - decouple state-access validation from EIP-2929 (stack/balance checks to pre-state; warming+BAL paired with post-state cost) <https://github.com/ethereum/EIPs/compare/master...nerolation:EIPs:toni/state-access> R&D discussion <https://discord.com/channels/595666850260713488/1506543443172921464/1509797201340137544>

- Toni Wahrstätter
That's how it looks in EELS: https://github.com/ethereum/execution-specs/pull/2900
- Dragan Rakita
We need to change it too
- Karim T. (matkt)
I will prefer to test to implement it and see the impact before . But for the moment seems to not be a simple change (besu)

---------- Spec Changes: 8037 calldata floor (merged) ---------- 🧾 EIP-8037 - calldata floor accounting alignment & call-frame refill clarification <https://github.com/ethereum/EIPs/pull/11706> ---------- Spec Changes: 8037 auth refunds ---------- 🧾 EIP-8037 - expand EIP-7702 authorization gas refunds (5-rule scheme) TLDR: want it or not? added complexity / attack vectors? <https://github.com/ethereum/EIPs/pull/11715>
- danceratopz
---------- Spec Changes: 2780 ---------- ⛽ EIP-2780 - remove self-transfer & precompile carve-outs TLDR: open Q - charge TRANSFER_LOG_COST for self-transfers (no 7708 log)? one cost or Code-vs-No-Code split? <https://github.com/ethereum/EIPs/pull/11735>
- Dragan Rakita
I am fine with the log part.
- Toni Wahrstätter
What about 7997?
- Toni Wahrstätter
the factory precompile
- my side I like the following below, and adding all EL changes and new EL EIPs
Launch two devnets simultaneously and merge into later devnet: i. glamsterdam-devnet-5 for CL stability. ii. bal-devnet-8 for close-to-final EL spec. iii. -> merge into glamsterdam-devnet-6.
- Stefan Starflinger
7997 is marked https://eips.ethereum.org/EIPS/eip-7773 as CFI

I mean, the Q about 7688 is, how do we get prysm/teku/lighthouse/grandine to become ready? we keep pushing it to “next devnet”

Replying to "the factory precompi..." It is bytecode that is deployed at 0x12 address
- Toni Wahrstätter
I'd keep 7997 in CFI for now and ask clients to double-check if we actually need it. E.g. this one: https://safefoundation.org/blog/safe-research-meet-erc-7955-no-private-key-required We shouldn't include it just because it's small but only if it makes much sense.
- danceratopz
Launch two devnets simultaneously and merge into later devnet: i. glamsterdam-devnet-5 for CL stability. ii. bal-devnet-8 for close-to-final EL spec. iii. -> merge into glamsterdam-devnet-6.
- Dragan Rakita
For repricing, I would be fine to change it to anything, just to test the change and later update it when we get better number. Just so we are not blocked by this.
- spencer
optimizations + benchmarking on bal-devnet-7 all new el eips and eip changes on glam-denvet-6 ELs should prio optimizations over glam-devnet-6 EIPs/changes?
- Maria Silva
Also would like to hear from erigon, geth and besu as they are still working on optimizations

okay then lets postpone it
- spencer
Replying to "Lets focus all EL ..." For clients that have optimizations complete, can you work on this so we have someone to test against?
- Ben Adams
More important to have a working glamsterdam devnet than adding more EL changes to it ahead of the other EL changes?
- Toni Wahrstätter
