+PEP 578: Python Runtime Audit Hooks
+-----------------------------------
+
+The PEP adds an Audit Hook and Verified Open Hook. Both are available from
+Python and native code, allowing applications and frameworks written in pure
+Python code to take advantage of extra notifications, while also allowing
+embedders or system administrators to deploy builds of Python where auditing is
+always enabled.
+
+See :pep:`578` for full details.

 asyncio
 -------
 
+Running ``python -m asyncio`` launches a natively async REPL.  This allows rapid
+experimentation with code that has a top-level :keyword:`await`.  There is no
+longer a need to directly call ``asyncio.run()`` which would spawn a new event
+loop on every invocation:
+
+.. code-block:: none
+
+    $ python -m asyncio
+    asyncio REPL 3.8.0
+    Use "await" directly instead of "asyncio.run()".
+    Type "help", "copyright", "credits" or "license" for more information.
+    >>> import asyncio
+    >>> await asyncio.sleep(10, result='hello')
+    hello
