+#### Added
+
+- During restore of a question_set_reference, mapping of IDs in the filtercondition is now delegated to qbank plugins. If your qbank plugin defines a filter condition that uses database IDs, add an override of `restore_filtercondition()` to the `condition` class, which checks the condition's data and replaces the IDs with mapped values if required. See  `qbank_managecategories\category_condition` for an example.
