Google Chrome Moves to a Two-Week Release Cadence

Google began rolling out Chrome 153 Stable to desktop, Android and iOS today, marking the start of a new two-week release schedule for major updates. The next version, Chrome 154, is slated for September 22. This replaces the four-week cycle introduced in 2021 and the earlier six-week rhythm.

Chrome previously delivered major updates every six weeks, shortened to four weeks in 2021. The 14-day cadence aims to reduce the lag between feature completion and user availability.

Google describes the two-week cadence as a win for the web, emphasizing tighter deployment windows, faster interoperability updates and quicker safety improvements across platforms. The change aligns major releases with weekly security patches, ensuring engine refactors reach users with minimal delay.
