+## Route Template
+
+The `_template` paramter is no longer renamed to `contentTemplate`. The
+CmfContentBundle has been adjusted accordingly. If you have your own
+controllers that expect a template argument, adjust them accordingly.
+
+   **Before**
+   ```php
+   $route = new Route();
+   $route->setParent($routeRoot);
+   ```
+
+   **After**
+   ```php
+   $route = new Route();
+   $route->setParentDocument($routeRoot);
+   ```
+
+## Configuration
+
+ * Removed the `route_basepath` setting, use `route_basepaths` instead.
+
+   **Before**
+   ```php
+   public function documentAction($contentDocument, $contentTemplate) {
+       ...
+   ```
+
+   **After**
+   ```php
+   public function documentAction($contentDocument, $template) {
+       ...
+   ```
