  \begin{itemize}

+ \item The string methods, \method{ljust()}, \method{rjust()}, and
+ \method{center()} now take a optional argument for specifying a
+ fill character other than a space.
+ 
  \item The \method{sort()} method of lists gained three keyword
  arguments, \var{cmp}, \var{key}, and \var{reverse}.  These arguments

  \item The \function{zip()} built-in function and \function{itertools.izip()}
!   now return an empty list instead of raising a \exception{TypeError}
    exception if called with no arguments.  This makes the functions more
    suitable for use with variable length argument lists:
