--- deprecations: - | The ``[glance]/allowed_direct_url_schemes`` configuration option and ``nova.image.download.modules`` extension point have been deprecated for removal. These were originally added for the *nova.image.download.file* FileTransfer extension which was removed in the 16.0.0 Pike release. The ``nova.image.download.modules`` extension point is not maintained and there is no indication of its use in production clouds. If you are using this extension point, please make the nova development team aware by contacting us in the #openstack-nova OFTC IRC channel or on the openstack-dev mailing list.
