Deprecation: #68183 - typo3/mod.php 

See forge#68183

Description 

The mod.php entry-point has been marked as deprecated. All Backend Module requests in the Backend using the Module Url API are not affected as they automatically use index.php.

Impact 

All extensions directly linking to typo3/mod.php will throw a deprecation warning.

Affected Installations 

Installations with custom extensions that call typo3/mod.php without using proper API calls from BackendUtility.

Migration 

Use BackendUtility::getModuleUrl().
