Chrome 149 introduces three notable features for web developers. CSS gap decorations allow styling of gaps in grid and flexbox layouts without complex hacks, with animatable properties like column-rule-inset and row-rule-inset. WebSocket connections no longer block pages from entering the Back/Forward Cache — the browser now proactively closes them on bfcache entry, enabling instant page restoration. Finally, Intl.Locale.prototype.variants is now available in Chrome, completing cross-browser support for accessing Unicode locale variant subtags.
