+========================================================
+Deprecation: #83904 - Array handling in AbstractTreeView
+========================================================
+
+See :issue:`83904`
+
+Description
+===========
+
+Handling arrays instead of database relations in class :php:`TYPO3\CMS\Backend\Tree\View\AbstractTreeView`
+has been marked as deprecated.
+
+
+Impact
+======
+
+Calling the following methods will throw deprecation warnings and will be removed with core version 10:
+
+* [scanned] :php:`AbstractTreeView->setDataFromArray`
+* [scanned] :php:`AbstractTreeView->setDataFromTreeArray`
+
+The following class properties should not be used any longer and will be removed with core version 10:
+
+* [not scanned] :php:`AbstractTreeView->data`
+* [scanned] :php:`AbstractTreeView->dataLookup`
+* [scanned] :php:`AbstractTreeView->subLevelID`
+
+
+Affected Installations
+======================
+
+This feature was rarely used, it is pretty unlikely an instance is affected by a consuming extension.
+The extension scanner will report most use cases.
+
+
+Migration
+=========
+
+No migration available.
