 ## 6.8.0-wip
 
 - Add type arguments to `Map` literals used for `Record` serialization.
-- Added support for generating `ExampleJsonKeys`, exposing a secured way to 
-  access the json keys from the properties.
-  ([#1164](https://github.com/google/json_serializable.dart/pull/1164))
+- Add support for `JsonSerializable(createJsonKeys: true)`.
+  ([#1401](https://github.com/google/json_serializable.dart/pull/1401))
 - Handle decoding an `int` value from a `double` literal. 
   This now matches the behavior of `double` values being encoded as `int`.
