+================================================================================================
+Breaking: #81763 - Hook parameters of ['typo3/file_edit.php']['preOutputProcessingHook'] changed
+================================================================================================
+
+See :issue:`81763`
+
+Description
+===========
+
+The hook parameters passed into :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/file_edit.php']['preOutputProcessingHook']`
+have been changed due to rewriting the edit file form to use FormEngine.
+
+
+Impact
+======
+
+Any information added to modify the output may have no effect anymore.
+
+
+Affected Installations
+======================
+
+Every installation using an extension that hooks into :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/file_edit.php']['preOutputProcessingHook']`
+to modify the form's output is affected.
+
+
+Migration
+=========
+
+As the form is based on FormEngine now, you may want to adjust the newly introduced hook parameter :php:`$dataColumnDefinition`,
+representing the definition of the `data` field which contains the file content. An example can be found in EXT:t3editor.
