In DW8 it was possible to render item pages that was not visible in navigation by using the ItemPublisher. In DW9 the item pages must be "Published" before they are available in the GetLoop("ItemPublisher:Items.List"). I think is a bug and item pages should be rendered if the status is "Published" or "Hide in menu", but not if they are "Unpublished".
