+Introduce :class:`asyncio.Stream` class that merges :class:`asyncio.StreamReader` and :class:`asyncio.StreamWriter` functionality.
+:class:`asyncio.Stream` can work in readonly, writeonly and readwrite modes.
+Provide :func:`asyncio.connect`, :func:`asyncio.connect_unix`, :func:`asyncio.connect_read_pipe` and :func:`asyncio.connect_write_pipe` factories to open :class:`asyncio.Stream` connections. Provide :class:`asyncio.StreamServer` and :class:`UnixStreamServer` to serve servers with asyncio.Stream API.
+Modify :func:`asyncio.create_subprocess_shell` and :func:`asyncio.create_subprocess_exec` to use :class:`asyncio.Stream` instead of deprecated :class:`StreamReader` and :class:`StreamWriter`.
+Deprecate :class:`asyncio.StreamReader` and :class:`asyncio.StreamWriter`.
+Deprecate usage of private classes, e.g. :class:`asyncio.FlowControlMixing` and :class:`asyncio.StreamReaderProtocol` outside of asyncio package.
