   * `bearer = true` attribute for [`jwt` block](https://docs.couper.io/configuration/block/jwt#attributes) to indicate retrieving token from `Authorization: Bearer ...`. This is the new default token source indicator. `header = "Authorization"` is now _deprecated_ in favour of this new attribute. ([#724](https://github.com/avenga/couper/pull/724))
   * If Couper starts with `-watch` CLI flag, watch referenced files, too ([#747](https://github.com/avenga/couper/pull/747))
 
+* **Changed**
