Python 2.3.7

We are pleased to announce Python 2.3.7 (final), a bugfix release of Python 2.3, on March 11, 2008.

Important: 2.3.7 is a source-only release. If you need a binary release of 2.3, use 2.3.5. If you need the fixes that are included in this release, use 2.5.2 or later.

Python 2.3 is now well and truly in bugfix-only mode; no new features are being added, and only security critical bugs have been fixed. This release addresses a number of cases interpreter might have crashed in certain boundary conditions.

See the detailed release notes for more details.

Python 2.5 and Python 2.4 are newer releases of Python. This release of the older 2.3 code is to provide bug fixes for people who are still using Python 2.3.

For more information on the new features of Python 2.3 see the 2.3 highlights or consult Andrew Kuchling's What's New In Python for a more detailed view.

Since the release candidate, we received various reports that the this release may fail to build on current operating systems, in particular on OS X. We have made no attempt to fix these problems, as the release is targeted for systems that were current at the time Python 2.3 was originally released. For more recent systems, you might have to come up with work-arounds. For OS X in particular, try invoking:

./configure MACOSX_DEPLOYMENT_TARGET=10.5

Please see the separate bugs page for known issues and the bug reporting procedure.

Download the release

As noted, python.org is not providing binary installers for 2.3.7. Windows and Mac OS X users who cannot compile their own versions should continue to use the 2.3.5 installers. These installers are not vulnerable to PSF-2006-001.

gzip-compressed source code: Python-2.3.7.tgz

bzip2-compressed source code: Python-2.3.7.tar.bz2, the source archive.

The bzip2-compressed version is considerably smaller, so get that one if your system has the appropriate tools to deal with it.

Unpack the archive with tar -zxvf Python-2.3.7.tgz (or bzcat Python-2.3.7.tar.bz2 | tar -xf -). Change to the Python-2.3.7 directory and run the "./configure", "make", "make install" commands to compile and install Python. The source archive is also suitable for Windows users who feel the need to build their own version.
