+\item The \function{format()} function in the \module{locale} module
+has been modified and two new functions were added,
+\function{format_string()} and \function{currency()}.
+
+The \function{format()} function's \var{val} parameter could
+previously be a string as long as no more than one \%char specifier
+appeared; now the parameter must be exactly one \%char specifier with
+no surrounding text.  An optional \var{monetary} parameter was also
+added which, if \code{True}, will use the locale's rules for
+formatting currency in placing a separator between groups of three
+digits.
+
+To format strings with multiple \%char specifiers, use the new
+\function{format_string()} function that works like \function{format()}
+but also supports mixing \%char specifiers with
+arbitrary text.
+
+A new \function{currency()} function was also added that formats a
+number according to the current locale's settings.
