What's New

• The web-features npm package contains statuses computed for each browser compat data key associated with a feature, as the by_compat_key property of status objects. Previously, this data was only available via the data.extended.json release artifact published on GitHub or computing it yourself using compute-baseline. If you use compute-baseline's getStatus() method, consider using the precomputed data from web-features instead. (#3341)
