\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.)
