This article explains the new features in Python 2.4. No release date
|
|
for Python 2.4 has been set; expect that this will happen in 2004.
|
|
|
|
While Python 2.3 was primarily a library development release, Python
|
|
2.4 may extend the core language and interpreter in
|
|
as-yet-undetermined ways.
|
|
|
|
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 2.4.
|
|
% 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.
|
|
|

\section{Other Language Changes}
|
|
|
|
Here are all of the changes that Python 2.4 makes to the core Python
|
|
language.
|
|
|
|
\begin{itemize}
|
|
\item TBD
|
|
|
|
\end{itemize}

\subsection{Optimizations}
|
|
|
|
\begin{itemize}
|
|
|
|
\item Optimizations should be described here.
|
|
|
|
\end{itemize}
|
|
|
|
The net result of the 2.4 optimizations is that Python 2.4 runs the
|
|
pystone benchmark around XX\% faster than Python 2.3 and YY\% faster
|
|
than Python 2.2.
|
|
|

\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 The \module{curses} modules now supports the ncurses extension
|
|
\function{use_default_colors()}. On platforms where the terminal
|
|
supports transparency, this makes it possible to use a transparent background.

\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.

\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 CVS change
|
|
logs finds there were XXX patches applied and YYY bugs fixed between
|
|
Python 2.3 and 2.4. Both figures are likely to be underestimates.
|
|
|
|
Some of the more notable changes are:
|
|
|
|
\begin{itemize}
|
|
|
|
\item Details go here.

\section{Porting to Python 2.4}
|
|
|
|
This section lists previously described changes that may require
|
|
changes to your code:
|
|
|
|
\begin{itemize}
|
|
|
|
\item dircache.listdir now passes exceptions to the caller,
|
|
instead of returning empty lists.
|
|
|
|
\end{itemize}
