Note: See Python 2.3.5 for a patch release release which supersedes earlier releases of 2.3.
Important: 2.3.5 includes a security fix for SimpleXMLRPCServer.py.
We are pleased to announce the release of Python 2.3 on July 29, 2003. This is a final, stable release, and we recommend Python users upgrade to this version.
Nineteen months in the making, Python 2.3 represents a commitment to stability and improved performance, with a minimum of new language features. Countless bugs and memory leaks have been fixed, many new and updated modules have been added, and the new type/class system introduced in Python 2.2 has been significantly improved. Python 2.3 can be up to 30% faster than Python 2.2.
Please see the separate bugs page for known issues and the bug reporting procedure.
Download the release
Windows users should download the Windows installer, Python-2.3.exe, run it and follow the friendly instructions on the screen to complete the installation. Windows users may also be interested in Mark Hammond's win32all, a collection of Windows-specific extensions including COM support and Pythonwin, an IDE built using Windows components.
All others should download Python-2.3.tgz, the source archive. Unpack it with "tar -zxvf Python-2.3.tgz". Change to the Python-2.3 directory and run the "./configure", "make", "make install" commands to compile and install Python.
Macintosh users can find binaries and source on Jack Jansen's MacPython page. Mac OS X users who have a C compiler (which comes with the OS X Developer Tools) can also build from the source tarball below.
The documentation has been updated too:
The interim documentation for new-style classes, last seen for Python 2.2.3, is still relevant for Python 2.3. In addition, The Python 2.3 Method Resolution Order is a nice paper by Michele Simionato that explains the C3 MRO algorithm (new in Python 2.3) clearly. (Also available as reStructured Text.
