The Cloud Pub/Sub preview gained a number of features, including a high-throughput Subscriber client for receiving messages from Cloud Pub/Sub.
The Subscriber supports at-least-once delivery subscriptions. It handles lease management. It exposes flow control configuration. It includes idle stream keepalives.
The Subscriber does not yet support stream retries (so sessions timeout after ~30 minutes), exactly-once delivery, or mocking. We are working on these.
Your feedback is greatly appreciated while we stabilize this API!

The Cloud Storage client now supports open_object().
This operation allows you to open an object and then perform multiple ranged reads on the object.
Each ranged read has lower latency than performing the read by itself.
Note that this features is under an allow list, contact your account team to include your project into the list.
