Misc/NEWS.d/next/Build/2020-05-19-10-54-08.bpo-40683.W8JHrr.rst

-Fixed an issue where the :mod:`zoneinfo` module and its tests were not
-included when Python is installed with ``make``.

Misc/NEWS.d/next/Build/2020-06-08-19-57-05.bpo-40684.WIY2-i.rst

-``make install`` now uses the ``PLATLIBDIR`` variable for the destination
-``lib-dynload/`` directory when ``./configure --with-platlibdir`` is used.

Misc/NEWS.d/next/Build/2020-06-15-22-14-25.bpo-36020.wbiv0P.rst

-The C99 functions :c:func:`snprintf` and :c:func:`vsnprintf` are now required
-to build Python.

Misc/NEWS.d/next/Build/2020-06-25-06-59-13.bpo-40204.GpD04D.rst

-Pin Sphinx version to 2.3.1 in ``Doc/Makefile``.

Misc/NEWS.d/next/Build/2020-08-24-18-34-01.bpo-41617.sKKXz7.rst

-Fix ``pycore_bitutils.h`` header file to support old clang versions:
-``__builtin_bswap16()`` is not available in LLVM clang 3.0.

Misc/NEWS.d/next/Build/2020-09-28-21-56-51.bpo-38249.uzMCaZ.rst

-Update :c:macro:`Py_UNREACHABLE` to use __builtin_unreachable() if only the
-compiler is able to use it. Patch by Dong-hee Na.

Misc/NEWS.d/next/C API/2020-02-08-08-01-35.bpo-39583.qURKSl.rst

-Remove superfluous "extern C" declarations from ``Include/cpython/*.h``.

Misc/NEWS.d/next/C API/2020-05-20-19-11-12.bpo-40703.qQXfW8.rst

-The PyType_FromSpec*() functions no longer overwrite the type's "__module__" attribute
-if it is set via "Py_tp_members" or "Py_tp_getset".

Misc/NEWS.d/next/C API/2020-05-26-16-21-47.bpo-39573.depAgq.rst

-Convert :c:func:`Py_REFCNT` and :c:func:`Py_SIZE` macros to static inline
-functions. They cannot be used as l-value anymore: use
-:c:func:`Py_SET_REFCNT` and :c:func:`Py_SET_SIZE` to set an object reference
-count and size. This change is backward incompatible on purpose, to prepare
-the C API for an opaque :c:type:`PyObject` structure.

Misc/NEWS.d/next/C API/2020-05-27-11-02-15.bpo-40792.pBw2Bb.rst

-The result of :c:func:`PyNumber_Index` now always has exact type :class:`int`.
-Previously, the result could have been an instance of a subclass of ``int``.

Misc/NEWS.d/next/C API/2020-06-01-16-12-37.bpo-40826.zQzFoK.rst

-:c:func:`PyOS_InterruptOccurred` now fails with a fatal error if it is
-called with the GIL released.

Misc/NEWS.d/next/C API/2020-06-01-20-47-49.bpo-40839.bAi52Z.rst

-Calling :c:func:`PyDict_GetItem` without :term:`GIL` held had been allowed for
-historical reason. It is no longer allowed.

Misc/NEWS.d/next/C API/2020-06-03-17-48-13.bpo-40679.3sgWma.rst

-Fix a ``_PyEval_EvalCode()`` crash if *qualname* argument is NULL.

Misc/NEWS.d/next/C API/2020-06-04-08-01-23.bpo-40724.qIIdSi.rst

-Allow defining buffer slots in type specs.

Misc/NEWS.d/next/C API/2020-06-08-15-59-06.bpo-40910.L56oI0.rst

-Export explicitly the :c:func:`Py_GetArgcArgv` function to the C API and
-document the function. Previously, it was exported implicitly which no
-longer works since Python is built with ``-fvisibility=hidden``.

Misc/NEWS.d/next/C API/2020-06-10-18-37-26.bpo-40943.i4q7rK.rst

-The ``PY_SSIZE_T_CLEAN`` macro must now be defined to use
-:c:func:`PyArg_ParseTuple` and :c:func:`Py_BuildValue` formats which use ``#``:
-``es#``, ``et#``, ``s#``, ``u#``, ``y#``, ``z#``, ``U#`` and ``Z#``.
-See :ref:`Parsing arguments and building values <arg-parsing>` and the
-:pep:`353`.

Misc/NEWS.d/next/C API/2020-06-15-16-46-01.bpo-36020.djI6jw.rst

-On Windows, ``#include "pyerrors.h"`` no longer defines ``snprintf`` and
-``vsnprintf`` macros.
