+### BREAKING CHANGES
+
+* The transitive dependency punycode@2.1.0 needs Node version ">=6".
+* The setup.js is divided to multiple files.
+Therefore you need to change the import of the setup in your endpoint files
+like the following:
+
+    ```
+  // before
+  const SetupEndpoint = require('./setup/setup.js');
+
+  // now
+  const SetupEndpoint = require('./setup/index.js');
+
+  // or:
+  const SetupEndpoint = require('./setup/');
+  ```
