Chris Lowder updated the ECMAScript requirements in the raspberrypi/documentation repository, raising the standard from ES11 to ES13 and removing an outdated features list to streamline version guidance. Through careful technical writing and change management, Chris clarified documentation to better reflect current browser capabilities, reducing ambiguity for developers and aligning guidance with modern ECMAScript standards. The work focused on improving user-facing documentation using adoc, emphasizing clarity and maintainability. While the scope was limited to a single feature over one month, the update addressed a concrete need for clearer versioning information, supporting future feature planning and reducing potential support queries.
