Key New Features

 * Pre-signed URL - A new REST API endpoint to support pre-signed URL, which provides enough control over the resource being shared, without compromising security.
 * Email Notification - A new task driver for notification service, which can take a Zaqar subscriber's email address. When there is a new message posted to the queue, the subscriber will receive the message by email.
 * Policy Support - Support fine-grained permission control with the  file like most of the other OpenStack components.
 * Persistent Transport - Added support for websocket as a persistent transport alternative for Zaqar. Now users will be able to establish long-lived connections between their applications and Zaqar to interchange large amounts of data without the connection setup adding overhead.
