Google has released Chrome 151 to the stable channel, delivering a mix of user-facing, enterprise, and developer changes in the Chromium-based browser. The update adds new Gemini AI integrations, expands Safe Browsing protections, and improves PDF handling, while Google continues to distinguish Chrome from upstream Chromium through bundled components such as Google API integration, DRM support, and other Chrome-specific services. The release also keeps the Extended Stable channel available and indicates that Chrome 152 is planned as the next major version.
Chrome 151 also advances Google's transition away from legacy extensions by further restricting Manifest V2 add-ons, though enterprises retain a temporary policy option to allow older MV2 extensions during migration. On the platform side, the browser drops support for macOS 12 and now targets macOS 13+, while additional legacy browser features and APIs are being removed or deprecated, including older XML/XSLT-related functionality. The release further introduces web-platform updates for developers, including new HTML and PerformanceObserver capabilities, alongside broader changes affecting Windows, Linux, and macOS deployments.
