+==================================================================
+Breaking: #74533 - Throw exception if user function does not exist
+==================================================================
+
+See :issue:`74533`
+
+Description
+===========
+
+:php:`GeneralUtility::callUserFunction()` does now always throw an exception if the passed
+user function does not exist or is not callable. The parameter `$errorMode` has been removed,
+exceptions are now always thrown. The method should not be called with more than three arguments.
+
+
+Impact
+======
+
+Calling a not existing or uncallable user function leads to an exception, breaking the page output.
+
+
+Affected Installations
+======================
+
+All TYPO3 installations are affected.
+
+
+Migration
+=========
+
+Remove or fix invalid `userFunc` calls registered in TypoScript and/or `ext_localconf.php`. Catch exceptions properly
+with try/catch.
