% 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.

\title{What's New in Python 3.0}

|
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}
|

|
|

\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.

\section{Porting to Python 3.0}
|
|
|
|
This section lists previously described changes that may require
|
|
changes to your code:

|
|
|
|
\item Everything is all in the details!
