On Windows, the default event loop is now :class:`~asyncio.ProactorEventLoop`.
builtins
--------
The :func:`compile` built-in has been improved to accept the
``ast.PyCF_ALLOW_TOP_LEVEL_AWAIT`` flag. With this new flag passed,
:func:`compile` will allow top-level ``await``, ``async for`` and ``async with``
constructs that are usually considered invalid syntax. Asynchronous code object
marked with the ``CO_COROUTINE`` flag may then be returned.
