+Breaking: #63784 - Visibility and type of DataHandler->exclude_array
+====================================================================
+
+See :issue:`63784`
+
+Description
+===========
+
+The internal but formerly public property DataHandler->exclude_array is replaced by
+the protected property DataHandler->excludedTablesAndFields, which contains the
+combination of excluded table and field as key instead. This improves performance
+especially for bulk editing since many in_array()-checks can be avoided.
+
+
+Impact
+======
+
+Extensions using the DataHandler (former TCEMain) and changing the (former public)
+exclude_array to change access to tables and fields cannot do so anymore. Users need
+to have their access-rights set properly instead.
+
+
+Affected installations
+======================
+
+Installations using extensions that read or write the undocumented array exclude_array.
+
+
+Migration
+=========
+
+Remove code accessing DataHandler->exclude_array and configure the BE-User properly.
