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.
