Deprecation: #84981 - BackendUserAuthentication->simplelog()

See Issue #84981

Description

Method TYPO3\CMS\Core\Authentication\BackendUserAuthentication->simplelog() has been marked as deprecated.

Impact

The method has been a shortcut to writelog() which can be used instead.

Affected Installations

Instances with extensions that call this method. Calling the method will trigger a PHP E_USER_DEPRECATED error. The extension scanner should find possible usages.

Migration

Use writelog() instead or - even better - use the logging framework to log messages.
