+`4.0.0`_ (2021-01-23)
+---------------------
+
+General:
+
+- Dropped support for Python versions below 3.6.1.
+- Deprecated `ReceiptType.user_ack` has been removed. Use
+  `ReceiptType.user_acknowledge` instead.
+- `util.aio_run` has been simplified. It does not allow for passing a specific
+  event loop or closing the event loop on completion any longer.
+- `util.aio_run_proxy_decorator` has been renamed to `aio_run_proxy` and now
+  always creates the class instance within a running event loop.
+
+Client:
+
+- In async mode, creation of the `Connection` instance must now be done within
+  an `async` function.
+- If you have used a `with` context manager block in async mode before, you
+  must now do this within an `async with` asynchronous context manager. No
+  change is required in blocking mode.
+- `Connection.close` is now an async function.
+
+Server:
+
+- The callback server has been refactored and the `AbstractCallback` class has
+  been removed for more flexibility and control of the underlying
+  `aiohttp <https://docs.aiohttp.org>`_ server. Take a look at
+  `examples/callback.py` on how to use it.
+- The callback server CLI has been removed because it was redundant. The
+  example provides the same functionality.
