The entry list of the parameter $options has changed. The entry helpTextIdInline is replaced by the existing entry helpTextId.
Within the scripts groups-roles/lists_show.php and groups-roles/mylist.php the parameterrol_ids was replaced by role_list. With the name changed also the content of the parameter has changed.
