   ..c:macro:: Py_TPFLAGS_HAVE_VERSION_TAG

      This is a:term:`soft deprecated` macro that does nothing.
      Historically, this would indicate that the
 :c:member:`~PyTypeObject.tp_version_tag` field was available and
      initialized.


   ..c:macro:: Py_TPFLAGS_INLINE_VALUES

      This bit indicates that instances of this type will have an "inline values"
      array (containing the object's attributes) placed directly after the end
      of the object.

      This requires that:c:macro:`Py_TPFLAGS_HAVE_GC` is set.

      **Inheritance:**

      This flag is not inherited.

      ..versionadded::3.13


   ..c:macro:: Py_TPFLAGS_IS_ABSTRACT

      This bit indicates that this is an abstract type and therefore cannot
      be instantiated.

      **Inheritance:**

      This flag is not inherited.

      ..seealso::
 :mod:`abc`


   ..c:macro:: Py_TPFLAGS_HAVE_STACKLESS_EXTENSION

      Internal. Do not set or unset this flag.
      Historically, this was a reserved flag for use in Stackless Python.

      ..warning::
            This flag is present in header files, but is not be used.
            This may be removed in a future version of CPython.
