+====================================================================
+Deprecation: #89722 - GMENU_LAYERS related property TSFE->divSection
+====================================================================
+
+See :issue:`89722`
+
+Description
+===========
+
+The public PHP property :php:`TypoScriptFrontendController->divSection` has been marked as deprecated. This was used in prior
+TYPO3 versions to add dynamic JavaScript related to GMENU_LAYERS
+functionality which was removed with previous TYPO3 versions, making
+this property only produce unnecessary overhead in frontend rendering.
+
+
+Impact
+======
+
+Accessing or setting this property will trigger a deprecation notice.
+
+
+Affected Installations
+======================
+
+TYPO3 installations with extensions explicitly accessing this property, which is highly unlikely as this property is very lowlevel.
+
+
+Migration
+=========
+
+If there is a need to add JavaScript within uncached content, use
+:php:`$GLOBALS['TSFE']->additionalHeaderData[]` instead.
