Stable Release
7 weeks after the branch point a new major version is released. The stable rollout is staged over time so that any issues can be detected early and addressed before they reach all users. Each Chrome platform has a different stable rollout plan and the schedule below can vary based on circumstances:

Desktop: Desktop consists of three main platforms, Windows, Mac, and Linux. Linux is ramped up to 100% immediately. Mac and Windows follow a staged rollout as follows:
5% deployment ->15% deployment ->50% deployment ->100% deployment.
Android: Android releases both Chrome and WebView with each release, and follows a pattern similar to:
1% deployment -> 5% deployment -> 10% deployment -> 50% deployment -> 100% deployment.
iOS: iOS follows a phased release with no control over the following rollout percentage schedule:
Day 1: 1% -> Day 2: 2% -> Day 3: 5% -> Day 4: 10% -> Day 5: 20% -> Day 6: 50% -> Day 7: 100%.
