\chapter{New in Release 1.4}
This chapter describes additions to the Python language and library in
version 1.4.
\begin{itemize}
\item
Power operator. \code{x**y} is equivalent to \code{pow(x, y)}.
\item
Complex numbers. Imaginary literals are writen with a \code{'j'}
suffix (\code{'J'} is allowed for consistency.) Complex numbers with
a nonzero real component are written as
\code{(\var{real}+\var{imag}j)}. The usual arithmetic operators on
complex numbers are supported, so that e.g. \code{1j**2} equals
\code{-1.0}. Module \code{cmath} provides versions of all math
functions that take complex arguments and return complex results.
(Module \code{math} only supports real numbers, so that
\code{math.sqrt(-1)} still raises a \code{ValueError} exception.)
\item
New indexing syntax. It is now possible to use a tuple as an indexing
expression for a mapping object without parenthesizing it,
e.g. \code{x[1, 2, 3]}.
\item
New slicing syntax. In support of the Numerical Python extension
(distributed separately), slice indices of the form
\code{x[lo:hi:stride]} are possible, multiple slice indices separated by
commas are allowed, and an index position may be replaced by ellipses,
as follows: \code{x[a, ..., z]}. There's also a new built-in function
\code{slice(lo, hi, stride)} and a new built-in object
\code{Ellipses}, which yield the same effect without using special
syntax. None of the standard sequence types support indexing with
slice objects or ellipses yet. Note that when any of these extensions
are used, the mapping interface for indexing will be used.
\item
XXX More!!!
