+
+### Notable Implementation Changes
+
+- In subscription consumer thread: Making sure the request generator
+  attached to an inactive bidirectional streaming pull is stopped before
+  spawning a new request generator. This way we have a (fairly strong)
+  guarantee that requests in the queue don't get sent into an inactive
+  stream (#4503, #4554).
+- Adding `pause` / `resume` to subscription consumer thread and using these
+  methods during flow control. The previous implementation tried to close the
+  subscription (which involved 3 worker threads and 10 executors in a thread
+  pool) and then re-open a new subscription. But, this was not entirely
+  possible to shut down correctly from **within** one of the worker threads.
+  Instead, we only pause the worker (of the 3) that is pulling new responses
+  from the bidirectional streaming pull (#4558).
+- **Bug fix** (#4516): Using `max` where `min` was used by mistake to
+  ensure the number of bytes tracked for subscription flow control
+  remained non-negative (#4514).
+- Raising `TypeError` if `SubscriberClient.subscribe` receives a
+  non-callable callback (#4497).
+- Shutting down thread pool executor when closing a subscriber
+  policy (#4522).
+- Renaming `Policy.on_callback_request` to `Policy.dispatch_callback`
+  and making the behavior much less dynamic (#4511).
+- Make sure subscription consumer thread doesn't try to join itself
+  when exiting in error (#4540).
+
+### Dependencies
+
+- Upgrading `google-api-core` dependency to latest revision (`0.1.2`)
+  since we rely on the latest version of the `concurrent.futures` backport
+  to provide the `thread_name_prefix` argument for thread pool
+  executor (#4521, #XYZ).
