Deprecation: #86179 - Protected render() method in BackendController

See forge#86179


Method TYPO3\CMS\Backend\Controller\BackendController->render() has changed visibility from public to protected and should not be called any longer.


Calling the method from an external object triggers a PHP E_USER_DEPRECATED error.

Affected Installations

This internal method is usually not called by extensions directly. Since the method name is so generic, the extension scanner is not configured to search for usages, it would trigger far too many false positives.


Use route target main instead that calls method mainAction and returns a proper PSR-7 Response object.
