+=======================================================================
+Deprecation: #94957 - TypoScriptFrontendController->cObjectDepthCounter
+=======================================================================
+
+See :issue:`94957`
+
+Description
+===========
+
+The :php:`TypoScriptFrontendController` contains a property to prevent endless
+recursion of content objects during frontend rendering. With TypoScript
+becoming less complex, this check becomes obsolete. To reduce dependencies
+between :php:`TypoScriptFrontendController` and :php:`ContentObjectRenderer`,
+the handling has been removed and property :php:`TypoScriptFrontendController->cObjectDepthCounter`
+has been marked as deprecated.
+
+
+Impact
+======
+
+If a TypoScript setup somehow manages to create a recursion, PHP will now stop
+with a fatal PHP nesting level error at some point, instead TYPO3 frontend
+rendering silently stopping.
+
+
+Affected Installations
+======================
+
+Instances using property :php:`TypoScriptFrontendController->cObjectDepthCounter`
+are affected. That property has been handled mostly internally, this case is unlikely.
+The extension scanner will find usages with a weak match.
+
+
+Migration
+=========
+
+Drop usages of property :php:`TypoScriptFrontendController->cObjectDepthCounter`,
+it is unused within TYPO3 v11.
