+====================================================================
+Breaking: #92060 - Dropped class TYPO3\CMS\Backend\View\PageTreeView
+====================================================================
+
+See :issue:`92060`
+
+Description
+===========
+
+Class :php:`TYPO3\CMS\Backend\View\PageTreeView` has been
+dropped without substitution.
+
+
+Impact
+======
+
+Extensions using or extending this class may throw fatal PHP errors.
+
+
+Affected Installations
+======================
+
+This core internal class has been unused for a while in the core. There is little
+chance some extension depends on it. The extension scanner finds affected
+extensions with a strong match.
+
+
+Migration
+=========
+
+If still needed, copy the class code from an older core version to the affected extension,
+adapt namespace and usages.
