:c:func:Py_EndInterpreter now explicitly untracks all objects currently tracked by the GC. Previously, if an object was used later by another interpreter, calling :c:func:PyObject_GC_UnTrack on the object crashed if the previous or the next object of the :c:type:!PyGC_Head structure became a dangling pointer.

The main interpreter in _PyRuntimeState.interpreters is now statically allocated (as part of _PyRuntime). Likewise for the initial thread state of each interpreter. This means less allocation during runtime init, as well as better memory locality for these key state objects.

.. bpo: 46257 .. date: 2022-01-04-11-04-20 .. nonce: _o2ADe .. section: Library

Optimized the mean, variance, and stdev functions in the statistics module. If the input is an iterator, it is consumed in a single pass rather than eating memory by conversion to a list. The single pass algorithm is about twice as fast as the previous two pass code.

EntryPoint objects are no longer tuples. Recommended means to access is by attribute ('.name', '.group') or accessor ('.load()'). Access by index is deprecated and will raise deprecation warning.

Calling :meth:add_argument_group on an argument group is deprecated. Calling :meth:add_argument_group or :meth:add_mutually_exclusive_group on a mutually exclusive group is deprecated.

These features were never supported and do not always work correctly. The functions exist on the API by accident through inheritance and will be removed in the future.

The registry() method of :func:functools.singledispatch functions checks now the first argument or the first parameter annotation and raises a TypeError if it is not supported. Previously unsupported "types" were ignored (e.g. typing.List[int]) or caused an error at calling time (e.g. list[int]).

:c:func:PyBuffer_GetPointer, :c:func:PyBuffer_FromContiguous, :c:func:PyBuffer_ToContiguous and :c:func:PyMemoryView_FromBuffer now take buffer info by const Py_buffer * instead of Py_buffer *, as they do not need mutability. :c:func:PyBuffer_FromContiguous also now takes the source buffer as const void *, and similarly :c:func:PyBuffer_GetPointer takes the strides as const Py_ssize_t *.
