% Rules for maintenance:
% 
%  * Anyone can add text to this document.  Do not spend very much time
%    on the wording of your changes, because your text will probably
%    get rewritten to some degree.
%
%  * The maintainer will go through Misc/NEWS periodically and add
%    changes; it's therefore more important to add your changes to 
%    Misc/NEWS than to this file.
%
%  * This is not a complete list of every single change; completeness
%    is the purpose of Misc/NEWS.  Some changes I consider too small
%    or esoteric to include.  If such a change is added to the text,
%    I'll just remove it.  (This is another reason you shouldn't spend
%    too much time on writing your addition.)
%
%  * If you want to draw your new text to the attention of the
%    maintainer, add 'XXX' to the beginning of the paragraph or
%    section.
%
%  * It's OK to just add a fragmentary note about a change.  For
%    example: "XXX Describe the transmogrify() function added to the
%    socket module."  The maintainer will research the change and
%    write the necessary text.
%
%  * You can comment out your additions if you like, but it's not
%    necessary (especially when a final release is some months away).
%
%  * Credit the author of a patch or bugfix.   Just the name is
%    sufficient; the e-mail address isn't necessary.
%
%  * It's helpful to add the bug/patch number as a comment:
%
%       % Patch 12345
%       XXX Describe the transmogrify() function added to the socket
%       module.
%       (Contributed by P.Y. Developer.)
%
%    This saves the maintainer the effort of going through the SVN log
%    when researching a change.

This article explains the new features in Python 3.0.  No release date
for Python 3.0 has been set; it will probably be released in mid 2008.

% Compare with previous release in 2 - 3 sentences here.

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 3.0.
% add hyperlink when the documentation becomes available online.
If you want to understand the complete implementation and design
rationale, refer to the PEP for a particular new feature.


%======================================================================

% Large, PEP-level features and changes should be described here.

% Should there be a new section here for 3k migration?
% Or perhaps a more general section describing module changes/deprecation?
% sets module deprecated

%======================================================================
\section{Other Language Changes}

Here are all of the changes that Python 2.6 makes to the core Python
language.

\begin{itemize}

\item Detailed changes are listed here.

\end{itemize}


%======================================================================
\subsection{Optimizations}

\begin{itemize}

\item Detailed changes are listed here.

\end{itemize}

The net result of the 3.0 optimizations is that Python 3.0 runs the
pystone benchmark around XX\% slower than Python 2.6.


%======================================================================
\section{New, Improved, and Deprecated Modules}

As usual, Python's standard library received a number of enhancements and
bug fixes.  Here's a partial list of the most notable changes, sorted
alphabetically by module name. Consult the
\file{Misc/NEWS} file in the source tree for a more
complete list of changes, or look through the CVS logs for all the
details.

\begin{itemize}

\item Detailed changes are listed here.

\end{itemize}


%======================================================================
% whole new modules get described in \subsections here


% ======================================================================
\section{Build and C API Changes}

Changes to Python's build process and to the C API include:

\begin{itemize}

\item Detailed changes are listed here.

\end{itemize}


%======================================================================
\subsection{Port-Specific Changes}

Platform-specific changes go here.


%======================================================================
\section{Other Changes and Fixes \label{section-other}}

As usual, there were a bunch of other improvements and bugfixes
scattered throughout the source tree.  A search through the change
logs finds there were XXX patches applied and YYY bugs fixed between
Python 2.6 and 3.0.  Both figures are likely to be underestimates.

Some of the more notable changes are:

\begin{itemize}

\item Details go here.

\end{itemize}


%======================================================================
\section{Porting to Python 3.0}

This section lists previously described changes that may require
changes to your code:

\begin{itemize}

\item Everything is all in the details!

\end{itemize}
