 Features:
   - Added two new configuration options, `filter_payload_with_whitelist` and `whitelist_payload_shape`
     - See [README.md](https://github.com/MindscapeHQ/raygun4ruby#filtering-the-payload-by-whitelist) for an example of how to use them
+  - When raygun4ruby encounters an exception trying to track an exception it will try once to send that exception to Raygun so you are notified
 
 Bugfixes:
   - raygun4ruby will no longer crash and suppress app exceptions when the API key is not configured
