Apr 1, 2025Monthly summary for 2025-04 (sigp/lighthouse): This period delivered key features and targeted fixes with a clear business impact. Key features included an upgrade of the consensus testing infrastructure to v1.5.0-beta.4, with CI aligned to the latest consensus specs by updating the Makefile tag and excluding new test directories (eip7441 and eip7732) from file-access checks. A standardization effort consolidated network message size handling to MAX_PAYLOAD_SIZE and removed the obsolete MAX_CHUNK_SIZE, simplifying configuration for networks post-merge.
