 ## [1.1.0] - 2021-10-12
 This version of the client drops support for the older server versions without changing the API. `ScanPolicy.fail_on_cluster_change`, `ScanPolicy.scan_percent` and `BasePolicy.priority` are deprected for the Scan operations and will not be sent to the server. They remain in the API to avoid breaking the API.
