Ylem Kim worked on the hamishwillee/content repository, focusing on the deprecation of the Related Website Sets feature. They updated documentation and the privacy sandbox guide using Markdown, ensuring that developers and product teams were clearly informed about the feature’s deprecated status and the shift toward privacy-focused alternatives. Their work aligned documentation with evolving web standards and privacy requirements, advising developers to avoid further use of the feature. While the scope was limited to a single feature and did not involve bug fixes, Ylem’s contribution improved governance clarity and supported the migration to more privacy-conscious solutions within the project’s documentation.
