=======

* 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.

/*[clinic input]
sys.callstats

Return a tuple of function call statistics.

A tuple is returned only if CALL_PROFILE was defined when Python was
built. Otherwise, this returns None.

When enabled, this function returns detailed, implementation-specific
details about the number of function calls executed. The return value
is a 11-tuple where the entries in the tuple are counts of:
0. all function calls
1. calls to PyFunction_Type objects
2. PyFunction calls that do not create an argument tuple
3. PyFunction calls that do not create an argument tuple
and bypass PyEval_EvalCodeEx()
4. PyMethod calls
5. PyMethod calls on bound methods
6. PyType calls
7. PyCFunction calls
8. generator calls
9. All other calls
10. Number of stack pops performed by call_function()
