Oguzhan Kaymak focused on enhancing the documentation for the primev/mev-commit-docs repository, specifically targeting the Preconf Builder RPC endpoints. He updated the best practices guide to replace direct IP:port references with the more descriptive /execution/rpc endpoint for versions v0.6.3 and v0.7.0, aiming to improve clarity for developers integrating these services. Working primarily with Markdown and leveraging his documentation skills, Oguzhan aligned the documentation with current builder RPC standards. This update reduced potential confusion during onboarding and integration, though the scope was limited to a single feature and did not involve code changes or bug fixes during the period.
