--- upgrade: - | In order to simplify initial setup for new installations the default behaviour of the Quobyte driver for the options ``nas_secure_file_operations`` and ``nas_secure_file_permissions`` has changed. The 'auto' values are no longer mapped to true but to false. Therefore the old default behaviour to run with secure settings is changed to run without secure settings as the new default behaviour. Installations using the default values for these options should ensure to explicitly set them to true with this new Cinder Quobyte driver version.
