 * If you used `clearAll()` or `clearAllAssignments()` of `yii\rbac\DbManager`, you should replace
   them with `removeAll()` and `removeAllAssignments()` respectively.
+
 * If you created RBAC rule classes, you should modify their `execute()` method by adding `$user`
   as the first parameter: `execute($user, $item, $params)`. The `$user` parameter represents
   the ID of the user currently being access checked. Previously, this is passed via `$params['user']`.
+
+* If you override `yii\grid\DataColumn::getDataCellValue()` with visibility `protected` you have
+  to change visibility to `public` as visibility of the base method has changed.
