Deprecation: #85707 - LoginFramesetController

See Issue #85707

Description

The class TYPO3\CMS\Backend\Controller\LoginFramesetController builds a simple HTML frameset and has been replaced by using the full logic within LoginController or a request to index.php?loginRefresh=1 directly.

Impact

Instantiating the LoginFramesetController class will trigger a PHP E_USER_DEPRECATED error.

Affected Installations

TYPO3 installations with custom logic using the rare functionality of LoginFramesetController.

Migration

Reference index.php?loginRefresh=1 in the callers code directly, or re-implement the frameset if necessary.
