Deprecation: #95083 - Backend toolbar CacheActions hook

See Issue #95083

Description

The TYPO3 hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['additionalBackendItems']['cacheActions'] which can be used to modify the cache actions, shown in the TYPO3 Backend top toolbar, has been marked as deprecated.

The accompanied PHP interface for the hook TYPO3\CMS\Backend\Toolbar\ClearCacheActionsHookInterface has been marked as deprecated as well.

Impact

If the hook is registered in a TYPO3 installation, a PHP E_USER_DEPRECATED error is triggered. The extension scanner also detects any usage of the deprecated interface as strong, and the definition of the hook as weak match.

Affected Installations

TYPO3 installations with custom extensions using this hook.

Migration

Migrate to the newly introduced \TYPO3\CMS\Backend\Backend\Event\ModifyClearCacheActionsEvent PSR-14 event.
