Deprecation: #67471 - Deprecate init.php

See forge#67471


In order to move all unneeded files from typo3/, the often used init.php has been deprecated in favor of using the bootstrap initialization code directly in the TYPO3 Backend.


All entry points from third-party extensions using init.php will now throw a deprecation warning.

Affected Installations

All instances having extensions that include init.php when not using the mod.php for modules or ajax calls.


Use the following code instead of the init.php inclusion if you still need custom entry points:

define('TYPO3_MODE', 'BE');

require __DIR__ . '/sysext/core/Classes/Core/Bootstrap.php';

If using a module, use the mod.php to register your own module.
