py_compile
----------

:func:`py_compile.compile` -- and by extension, :mod:`compileall` -- now
respects the :envvar:`SOURCE_DATE_EPOCH` environment variable by
unconditionally creating ``.pyc`` files for hash-based validation.
This allows for guaranteeing
`reproducible builds <https://reproducible-builds.org/>`_ of ``.pyc``
files when they are created eagerly. (Contributed by Bernhard M. Wiedemann

=======================

* :mod:`py_compile` and :mod:`compileall` now support the
:envvar:`SOURCE_DATE_EPOCH` environment variable by unconditionally
building ``.pyc`` files for hash verification instead of potentially
timestamp-based ``.pyc`` files. See the notes for the `py_compile`_
improvement notes for more details.

* A full copy of libffi is no longer bundled for use when building the
:mod:`_ctypes <ctypes>` module on non-OSX UNIX platforms. An installed copy
of libffi is now required when building ``_ctypes`` on such platforms.
