 ### Breaking Changes:
 
-- 0.5.0 - this breaking change _does not_ effect users using `jsonSchema()` or `json5Schema()` modes, but those using the "custom path".
+- 0.5.0 - this breaking change only impacts those following the "custom usage" approach, it _does not_ effect users using the high level, "bundled" `jsonSchema()` or `json5Schema()` modes. See the custom usages below to learn how to use the new `stateExtensions` and `handleRefresh` exports.
