### v5.0.1 – 2017-02-23

* Add the `CLIENT_ACTION_REQUIRED` response code to the Transaction resource's `POST` method. Similar to the Identity resource's `POST` method, this lets the Bango Platform support payment routes that require user interactions. Currently, the only action that may be returned by the API is `REDIRECT`. Other actions may be added later.

### v5.0.0

* Initial release of the Bango Payment API version 5
