+---------------
+
+ * The default value of the parameter `session`.`cookie_httponly` is now `true`.
+   It prevents scripting languages, such as JavaScript to access the cookie,
+   which help to reduce identity theft through XSS attacks. If your
+   application needs to access the session cookie, override this parameter:
+
+   ```yaml
+   framework:
+       session:
+           cookie_httponly: false
+   ```
