{\large This article is a draft, and is currently up to date for
Python 2.3beta1. Please send any additions, comments or errata to the
Python 2.3rc1. Please send any additions, comments or errata to the

This article explains the new features in Python 2.3. The tentative
release date of Python 2.3 is currently scheduled for mid-2003.
release date of Python 2.3 is currently scheduled for August 2003.
This article doesn't attempt to provide a complete specification of
the new features, but instead provides a convenient overview. For
full details, you should refer to the documentation for Python 2.3,
such as the \citetitle[../lib/lib.html]{Python Library Reference} and
the \citetitle[../ref/ref.html]{Python Reference Manual}. If you want
to understand the complete implementation and design rationale for a
change, refer to the PEP for a particular new feature.

It's also possible to take the symmetric difference of two sets. This
is the set of all elements in the union that aren't in the
intersection. An alternative way of expressing the symmetric
difference is that it contains all elements that are in exactly one
intersection. Another way of putting it is that the symmetric
difference contains all elements that are in exactly one
set. Again, there's an alternative notation (\code{\^}), and an
in-place version with the ungainly name
\method{symmetric_difference_update()}.
