+## Updating from v3 to v4
+
+The following changes were made to the Application package between v3 and v4.
+
+### Access to input data
+
+Accessing the input data in the input attribute of the application can now only be done via the `getInput()`.
+
+```php
+// Old
+$app->input->getInt();
+
+// New
+$app->getInput()->getInt();
+```
+
+### Status on redirect
+
+When calling `$app->redirect()`, you can not hand over a boolean value for the status, but always have to use an integer representing the HTTP status code.
