+These are the steps to publish a regular release on npm and as a GitHub release:
 
 1. Determine if it should be a major, minor, or patch release.
 
    A major version is required for releases when:
 
-   - Previously valid references are invalid (for example, a group ID is renamed or a feature ID is removed)
-   - Types have incompatibly narrowed, widened, or otherwise changed (for example, a string value now accepts an array of strings or an ID has become a URL)
+   - Previously valid references are invalid (for example, a group ID is renamed or a feature ID is removed).
+   - Types have incompatibly narrowed, widened, or otherwise changed (for example, a string value now accepts an array of strings or an ID has become a URL). Changes to `data.schema.json` often indicates a major or minor version is required.
 
    A minor version is required for releases that contain only additions, such as new feature or new properties on existing types.
 
    Patch versions are required for releases that contain only routine data changes, such as updates to `compat_features` arrays or `support` objects.
