 **Notes:**
 
 * Alphas are generally less stable than beta releases. The cutoff between the two
-  corresponds to when the underlying Chromium version enters Chrome's Beta channel.
-* The `-alpha.1`, `-beta.1`, and `stable` dates are our solid release dates.
+  corresponds to when the underlying Chromium version enters Chrome's
+  [Beta channel](https://www.chromium.org/getting-involved/chrome-release-channels/), where Google

+* `-alpha.1` and stable releases are published on the dates listed in the schedule.
+  The prereleases in between, including `-beta.1`, don't have fixed dates.
+* `-beta.1` is released automatically once the release branch is on that Chromium
+  version. This is usually the scheduled date, but it can be a few days later.
 * We strive for weekly alpha/beta releases, but we often release more than scheduled.
-* All dates are our goals but there may be reasons for adjusting the stable deadline, such as security bugs.
