 -------
 
-* Add raw datagram socket functions to the event loop:
-  :meth:`~asyncio.AbstractEventLoop.sock_sendto`,
-  :meth:`~asyncio.AbstractEventLoop.sock_recvfrom` and
-  :meth:`~asyncio.AbstractEventLoop.sock_recvfrom_into`.
-  (Contributed by Alex Grönholm in :issue:`46805`.)
+* Added :class:`~asyncio.TaskGroup` class,
+  an :ref:`asynchronous context manager <async-context-managers>`
+  holding a group of tasks that will wait for all of them upon exit.
+  For new code this is recommended over using
+  :class:`~asyncio.create_task` and `~asyncio.gather` directly.
+  (Contributed by Yury Seliganov and others in :gh:`31270`.)
+
+* Added :func:`~asyncio.timeout` context manager for setting a timeout
+  on asynchronous operations. For new code this is recommended over
+  using :func:`~asyncio.wait_for` directly.
+  (Contributed by Andrew Svetlov in :gh:`31394`.)
+
+* Added :class:`~asyncio.Runner` class, which exposes the machinery
+  used by `:func:`~asyncio.run`.   (Contributed by Andrew Svetlov
+  in :gh:`31799`.)
 
-* Add :meth:`~asyncio.streams.StreamWriter.start_tls` method for upgrading
+* Added :class:`~asyncio.Barrier` class to the synchronization primitives
+  in the asyncio library, and :exc:`~asyncio.BrokenBarrierError`.
+  (Contributed by Yves Duprat and Andrew Svetlov in :gh:`87518`.)
+
+* Added :meth:`~asyncio.streams.StreamWriter.start_tls` method for upgrading
   existing stream-based connections to TLS. (Contributed by Ian Good in
   :issue:`34975`.)
 
-* Add :class:`~asyncio.Barrier` class to the synchronization primitives of
-  the asyncio library. (Contributed by Yves Duprat and Andrew Svetlov in
-  :gh:`87518`.)
