.. versionchanged:: 3.8
Added *cf_feature_version* field.

The available compiler flags are accessible as macros:

.. c:var:: int CO_FUTURE_DIVISION
.. c:namespace:: NULL

This bit can be set in *flags* to cause division operator ``/`` to be
interpreted as "true division" according to :pep:`238`.
.. c:macro:: PyCF_ALLOW_TOP_LEVEL_AWAIT
PyCF_ONLY_AST
PyCF_OPTIMIZED_AST
PyCF_TYPE_COMMENTS

See :ref:`compiler flags <ast-compiler-flags>` in documentation of the
:py:mod:`!ast` Python module, which exports these constants under
the same names.
