This release is optional, however we recommend updating as it includes stability fixes.

⚠️ Req/Res CL P2P Sync — By Default Is Disabled

As previously communicated, we are deprecating the Req/Res CL P2P sync protocol in op-node.

--syncmode.req-resp flag now defaults to false, meaning Req/Res CL P2P sync is disabled by default.

Operators that rely on Req/Resp sync should explicitly set the flag to true and also update their infrastructure with a healthy EL p2p network.

🤝 The corresponding op-geth version is v1.101702.1.
