Queengooborg contributed to the mdn/browser-compat-data repository, focusing on delivering accurate and maintainable browser compatibility data for core web APIs and CSS features. Over five months, they implemented and modernized TypeScript tooling, integrated Bun runtime support, and maintained dependencies to ensure up-to-date data and tooling reliability. Their work involved data curation, schema definition, and manual validation using JavaScript and JSON, addressing both feature additions and bug fixes. By aligning compatibility data with real browser implementations and automating workflows, Queengooborg improved data quality, reduced maintenance risk, and enabled frontend teams to make more informed decisions about cross-browser feature support.

Oct 1, 2025October 2025: Key delivery and data quality improvements for mdn/browser-compat-data. Delivered WebAssembly JSTag_static interface support, updating webassembly/api.json with mdn-bcd-collector data to reflect Chrome 115 and Firefox 131. Implemented broad accuracy updates across multiple APIs (background-repeat-x, background-repeat-y, GPUAdapter.isFallbackAdapter, SpeechRecognition, ExtendableCookieChangeEvent, Navigator.share data.text), including version adjustments and flag considerations (Chrome 140, Safari behind-flag, Firefox behind-pref). These changes enhance the reliability of compatibility data for developers and MDN content.

Jul 1, 2025July 2025 MDN browser-compat-data delivered substantial dataset updates across dependencies, CSS/HTML APIs, and cross-browser feature data, strengthening data accuracy and developer confidence. Key features delivered include dependency maintenance; Firefox CSS data updates (adding the `flex` and `flex-direction` properties) and related -moz entries; RTCStatsReport API framesDecoded/framesEncoded support; WebAssembly features coverage across major browsers (exceptionsFinal, jspi, multi-value, mutable-globals); and HTML <link> element sizes attribute updates. Major bugs fixed include Edge SVG data updates (foreignObject, set SVG, Edge ≤79 mirror) and fixing the obsolete version_removed feature test. These changes reduce maintenance risk, improve data quality, and support more precise compatibility decision-making for frontend teams.
