+Breaking: #97451 - Removed BackendController page hooks
+=======================================================
+
+See :issue:`97451`
+
+Description
+===========
+
+The hooks :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/backend.php']['constructPostProcess']`,
+:php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/backend.php']['renderPreProcess']`, and
+:php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/backend.php']['renderPostProcess']` have
+been removed in favor of a new PSR-14 event :php:`\TYPO3\CMS\Backend\Controller\Event\AfterBackendPageRenderEvent`.
+
+Additionally, the :php:`BackendController->addCss()` method has been removed without replacement,
+as it is no longer used.
+
+Impact
+======
+
+Any hook implementation registered is not executed anymore in
+TYPO3 v12.0+. The extension scanner will report possible usages.
+
+Affected Installations
+======================
+
+All TYPO3 installations using this hook in custom extension code.
+
+Migration
+=========
+
+The hooks are removed without deprecation in order to allow extensions
+to work with TYPO3 v11 (using the hook) and v12+ (using the new event).
+
+Use the :doc:`PSR-14 event <../12.0/Feature-97451-PSR-14EventsForBackendPageController>`
+as an improved replacement.
