+
+* JavaScript: Minor simplification in the template.
+
 #### 0.16.0.3
 
 * JavaScript/node.js: Each instance of a client now uses its own cookie jar automatically. You no longer need to depend on the `request` library to use generated clients. If you want access to the cookie jar use `api.cookieJar`.
