Overview
- Chrome rolled out version 153 on Tuesday, Sept. 8, 2026, and Google has begun publishing milestone updates every two weeks on desktop, Android and iOS.
- Google says the change aims to reduce the “N-day” patch gap by getting security fixes from the public codebase into users' hands faster to counter faster-moving, AI-enabled threats.
- For enterprises that cannot tolerate rapid feature churn, Google offers an Extended Stable channel that ships major milestones every eight weeks while backporting security fixes between milestones.
- The faster cadence also lets Google iterate on new features, including AI integrations, but it raises testing and update-management pressure for web developers and IT administrators who are urged to test Beta builds ahead of Stable releases.
- Chrome's shift follows an earlier shortening of milestones from six weeks to four weeks in 2021 and has prompted other browser makers such as Mozilla, Microsoft and Brave to move toward similar faster schedules.
