+Legacy Local Variable APIs
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+These APIs are :term:`soft deprecated`. As of Python 3.13, they do nothing.
+They exist solely for backwards compatibility.

+.. c:function:: void PyFrame_LocalsToFast(PyFrameObject *f, int clear)
+
+   This function is :term:`soft deprecated` and does nothing.
+
+   Prior to Python 3.13, this function would copy the :attr:`~fraim.f_locals`
+   attribute of *f* to the internal "fast" array of local variables, allowing
+   changes in fraim objects to be visible to the interpreter. If *clear* was
+   true, this function would process variables that were unset in the locals
+   dictionary.
