Chrome moves major releases to two weeks; security patches have their own cadence
Starting with Chrome 153, major releases move from every four weeks to every two. Security patches also have their own cadence, and restarting remains an important step in applying downloaded updates.
Two-week milestones, separate security updates
TechCrunch reports that Chrome 153, released September 8 on desktop, iOS and Android, begins the two-week milestone schedule. Features and completed changes can reach Stable sooner than under the four-week cadence.
Google’s security explanation distinguishes major milestones from weekly security updates and a pilot of two security releases per week. A two-week milestone cycle does not mean security fixes must wait for the next major version.
From public code to the running browser
Once a fix is visible in public code, attackers may examine the change too. Google aims to shorten the gap between a landed fix and protection on users’ machines.
Chrome prepares updates in the background and generally applies them at restart. Google is researching dynamic patching and smoother session restoration; that does not establish that every device already updates without restarting.
