Breaking: #97452 - Removed EditFileController hooks¶
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/file_edit.php']['postOutputProcessingHook'] have been removed.
The same behavior may be achieved using template overrides.
Any hook implementation registered is not executed anymore in TYPO3 v12.0+. The extension scanner will report possible usages.
All TYPO3 installations using these hook in custom extension code. This is pretty unlikely, since both hooks were of limited use.
