--- features: - | OpenStack operators can now make use of a new config option named `driver_updatable_metadata` to determine which share metadata updates the back end driver needs to be notified about. The config option contains list of share metadata keys. When the share's metadata gets updated and Manila identifies that the new metadata keys match the metadata keys from the provided list, the share back end will be notified and it will apply the necessary changes. The result will be communicated through user messages.
