+\item Two new macros can be used to indicate C functions that are
+local to the current file so that a faster calling convention can be
+used.  \cfunction{Py_LOCAL(\var{type})} declares the function as
+returning a value of the specified \var{type} and uses a fast-calling
+qualifier. \cfunction{Py_LOCAL_INLINE(\var{type})} does the same thing
+and also requests the function be inlined.  If
+\cfunction{PY_LOCAL_AGGRESSIVE} is defined before \file{python.h} is
+included, a set of more aggressive optimizations are enabled for the
+module; you should benchmark the results to find out if these
+optimizations actually make the code faster.  (Contributed by Fredrik
+Lundh at the NeedForSpeed sprint.)

 \item \cfunction{PyErr_NewException(\var{name}, \var{base},
 \var{dict})} can now accept a tuple of base classes as its \var{base}
 argument.  (Contributed by Georg Brandl.)
