Michael Berger focused on enhancing the accuracy of browser compatibility data in the mdn/browser-compat-data repository, addressing two key issues during the month. He updated compatibility records to reflect CSS rx and ry support in Safari 17.4 and clarified that Chrome Android does not support the WebAuthn large blob extension. Working primarily with JSON and YAML, Michael applied his expertise in browser compatibility, data management, and web standards to ensure developers have reliable information for decision-making. His contributions improved the repository’s data integrity, providing a more dependable resource for developers who rely on up-to-date compatibility and standards information in their workflows.
