 TODO
 
+#### AuthRequestError
+
+`AuthRequestError` now takes the complete `Authorizer` as final argument, instead of only the encoder.
+This is to facilitate the use of the `Logger` as described above.
+
+```bash
+find . -type f -name '*.go' | xargs sed -i \
+    -e 's/\bAuthRequestError(w, r, authReq, err, authorizer.Encoder())/AuthRequestError(w, r, authReq, err, authorizer)/g
+```
+
+Note: the sed regex might not find all uses if the local variables of the passed arguments use different names.

 #### CreateRouter
