+Fixes
+-----
+
+* AMQP Backend: Exceptions occurring while sending task results are now
+  propagated instead of silenced.
+
+    `celeryd` will then show the full traceback of these errors in the log.
+
+* AMQP Backend: No longer deletes the result queue after successful
+  poll, as this should be handled by the
+  :setting:`CELERY_AMQP_TASK_RESULT_EXPIRES` setting instead.
+
+* Windows: celeryd: Show error if running with `-B` option.
+
+    Running celerybeat embedded is known not to work on Windows, so
+    users are encouraged to run celerybeat as a separate service instead.
+
+* Windows: Utilities no longer output ANSI color codes on Windows
+
+* camqadm: Now properly handles Ctrl+C by simply exiting instead of showing
+  confusing traceback.
+
+* Windows: All tests are now passing on Windows.
+
+* Remove bin/ directory, and `scripts` section from setup.py.
+
+    This means we now rely completely on setuptools entrypoints.
+
+.. v220-experimental:
+
+Experimental
+------------
+
+* :class:`PublisherPool`: Experimental pool of task publishers and
+  connections to be used with the `retry` argument to `apply_async`.
+
+  The example code below will re-use connections and channels, and
+  retry sending of the task message if the connection is lost.
+
+  .. code-block:: python
+
+    from celery import current_app
+
+    # Global pool
+    pool = current_app().amqp.PublisherPool(limit=10)

+    def my_view(request):
+        with pool.acquire() as publisher:
+            add.apply_async((2, 2), publisher=publisher, retry=True)
