Deprecation: #84980 - BackendUserAuthentication->addTScomment() 

See forge#84980

Description 

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

Impact 

The method has been used to add comments to TSconfig at runtime, those comments however are never shown in the TYPO3 backend. Calling the method directly will trigger a PHP E_USER_DEPRECATED error.

Affected Installations 

Instances with extensions calling BackendUserAuthentication->addTScomment() will trigger a deprecation error. It is however rather unlikely that extensions rely on this widely unknown API method and method calls were mostly core internal. The extension scanner should find possible usages within extensions.

Migration 

Drop the method call.
