Glossary of terms:

• Fraction - percentage of global users who will receive this version during the given release time. Some platforms like Linux and iOS do not follow fractional rollouts.
• Start/End - when a release first became available and when it was replaced with a newer release. Note that ended versions are still available via version pinning.
• Webview - Android app which provides other apps with web page rendering services. This is a separate Android app from Chrome itself but uses the same Chrome source.
• Canary ASAN - Special canary build meant to help uncover bugs in canary releases.

Chrome Tracker uses the Chrome Version History API and is hosted on GitHub. Pull requests are welcome!
