+## Model property names with dot(s) generates an error
+
+Instead of showing a deprecation warning for model property names with dots,
+for example, `customer.name: 'string'`, an error is thrown in 3.0 for
+enforcing use of valid model property names.
+
+See [related code change](https://github.com/strongloop/loopback-datasource-juggler/pull/947) for more details.
