Removed
=======
+* The undocumented ``sys.callstats()`` function has been removed. Since Python
+ 3.7, it was deprecated and always returned ``None``. It required a special
+ build option ``CALL_PROFILE`` which was already removed in Python 3.7.
+ (Contributed by Victor Stinner in :issue:`37414`.)
+
* The ``sys.getcheckinterval()`` and ``sys.setcheckinterval()`` functions have
been removed. They were deprecated since Python 3.2. Use
:func:`sys.getswitchinterval` and :func:`sys.setswitchinterval` instead.
