+This crate releases every month. We release new major versions (with potentially
+breaking API changes) at most once a quarter, and release incremental minor
+versions in the intervening months. See [this ticket] for more details.

 and minor) from the `master` branch. How we handle PRs with breaking API changes
 is described in the [contributing] guide.
