Security
- bpo-41162: Audit hooks are now cleared later during finalization to avoid missing events.

Core and Builtins
- bpo-41247: Always cache the running loop holder when running asyncio.set_running_loop.
- bpo-41252: Fix incorrect refcounting in _ssl.c’s _servername_callback().
- bpo-41218: Python 3.8.3 had a regression where compiling with ast.PyCF_ALLOW_TOP_LEVEL_AWAIT would aggressively mark list comprehension with CO_COROUTINE. Now only list comprehension making use of async/await will tagged as so.

- bpo-41193: The write_history() atexit function of the readline completer now ignores any OSError to ignore error if the filesystem is read-only, instead of only ignoring FileNotFoundError and PermissionError.
- bpo-41043: Fixed the use of glob() in the stdlib: literal part of the path is now always correctly escaped.
- bpo-39384: Fixed email.contentmanager to allow set_content() to set a null string.
