+=====================================================
+Breaking: #75645 - Doctrine: migrate ext:backend/Tree
+=====================================================
+
+See :issue:`75645`
+
+Description
+===========
+
+This patch changes all database related functions to use the new Doctrine database API.
+The method :php:`getDatabaseConnection()` has been removed.
+
+
+Impact
+======
+
+Calls to the method :php:`AbstractTreeView::getDataInit()` will now return :php:`Statement` objects.
+All other :php:`AbstractTreeView::getData*` methods now expect such a :php:`Statement` object
+instead of a SQL resource.
+
+
+Affected Installations
+======================
+
+All installations using TreeViews extending the AbstractTreeView.
+
+
+Migration
+=========
+
+Migrate all calls that work with the result :php:`Statement` from TreeView to be able to
+handle :php:`Statement` objects.
