+### Semantic versioning
 
 * Changes to **types** in this repository are considered non-breaking and are usually released as PATCH or MINOR semver changes (otherwise every schema addition would be a major version upgrade).
 * It is highly recommended that you lock your package version to a specific PATCH release and upgrade with the expectation that types may be upgraded between any release.
