It is therefore marked as deprecated and will be removed with TYPO3 v12. Impact ====== Calling the hook will trigger a PHP :php:`E_USER_DEPRECATED` error. Affected Installations ====================== All installations with extensions installed that implement the hook. Migration ========= Migrate to use the public API only and use other options (such as :php:`allowAttributes`) in order to only run certain instructions on the :php:`RteHtmlParser` object. .. index:: RTE, NotScanned, ext:core
