+The built-in function \code{apply()} now has an optional third
+argument, which is a dictionary specifying any keyword arguments to be
+passed.  For example,
+\begin{verbatim}
+apply(parrot, (), {'voltage': 20, 'action': 'voomm'})
+\end{verbatim}
+is equivalent to
+\begin{verbatim}
+parrot(voltage=20, action='voomm')

+There is also a mechanism for functions and methods defined in an
+extension module (i.e., implemented in C or C++) to receive a
+dictionary of their keyword arguments.  By default, such functions do
+not accept keyword arguments, since the argument names are not
+available to the interpreter.

+\item
 In the effort of implementing keyword arguments, function and
 especially method calls have been sped up significantly -- for a
 method with ten formal parameters, the call overhead has been cut in

+There are new module \code{ni} and \code{ihooks} that support

 The \code{string.split()} and \code{string.splitfields()} functions
 are now the same function (the presence or absence of the second
 argument determines which operation is invoked); similar for
