Deprecation: #99592 - Deprecated "flushByTag" hook

See forge#99592


The hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/cache/frontend/class.t3lib_cache_frontend_abstractfrontend.php']['flushByTag'] has been marked as deprecated, since the recommended way for custom cache functionality is to implement a custom cache frontend, using the Frontend API.


Any hook implementation registered won't be executed anymore in TYPO3 v13. The extension scanner will report possible usages.

Affected installations

All installations making use of the deprecated hook.


Migrate corresponding functionality in the flushByTag() method of your own cache frontend implementation.
