+XXX How to cross-link?

+* PEP 343: The :keyword:`with` statement is now a standard feature and
+ no longer needs to be imported from the ``__future__``.
+
+* PEP 366: Explicit relative imports from a main module inside a package.
+ This enhances the usefulness of the :option:`-m` option.
+
+* PEP 370: Per-user ``site-packages`` directory.
+
+* PEP 371: The ``multiprocessing`` package. XXX Did anything change here?
+
+* PEP 3101: Advanced string formatting. Note: the 2.6 description
+ mentions the :method:`format` method for both 8-bit and Unicode
+ strings. In 3.0, only the :class:`str` type (text strings with
+ Unicode support) supports this method; the :class:`bytes` type does
+ not.
+
+* PEP 3105: Print as a function. This is now a standard feature and
+ no longer needs to be imported from the ``__future__``.
+
+* PEP 3110: Exception-handling changes. The ``except exc as var:``
+ syntax is now standard and ``except exc, var:`` is no longer supported.
+ (Of course, the ``as var`` part is still optional.)
+
+* PEP 3112: Byte literals. The ``b"..."`` string literal notation
+ (and its variants like ``b'...'``, ``b"""...""", and ``br'...`'')
+ now produces a literal of type :class:`bytes`. More about :class:`bytes`
+ below.
+
+* PEP 3116: New I/O library. The :module:`io` module is now the
+ standard way of doing file I/O, and the initial values of
+ ``sys.stdin``, ``sys.stdout`` and ``sys.stderr`` are now instances
+ of :class:`io.TextIOBase`. The builtin :func:`open` function is
+ now an alias for ``io.open`` and has additional keyword arguments:
+ ``encoding``, ``errors``, ``newline`` and ``closefd``.
+
+* PEP 3118: Revised buffer protocol. The old builtin
+ :function:`buffer` is no more; the new builtin
+ :function:`memoryview` provides (mostly) similar functionality.
+
+* PEP 3119: Abstract Base Classes (ABCs). These play a slightly more
+ prominent role in the language now, and builtin collection types like
+ :class:`dict` and :class:`list` conform to the :class:`Mapping` and
+ :class:`Sequence` protocol, correspondingly.
+
+* PEP 3127: Integer literal suport and syntax. As mentioned above,
+ the new octal literal notation is the only one supported, and binary
+ literals have been added.
+
+* PEP 3129: Class decorators. This speaks for itself.
+
+* PEP 3141: A type hierarchy for numbers. This is another new use of
+ ABCs, defining Python's "numeric tower".
+
+* XXX More.
