Python 2.2.1

Warning: Python 2.2.1 reached end-of-life. It is no longer supported and does not receive security updates. We recommend upgrading to the latest Python release.

Release date: April 10, 2002

Important: This release is vulnerable to the problem described in security advisory PSF-2006-001 "Buffer overrun in repr() of unicode strings in wide unicode builds (UCS-4)". This fix is included in Python 2.4.4 and Python 2.5. If you need to remain with Python 2.2, there's a patch available from the security advisory page.

We are pleased to announce the release of Python 2.2.1, on April 10, 2002. This is a bug-fix release for Python 2.2 and supersedes the 2.2 release.

Download the release

Windows users should download the Windows installer, Python-2.2.1.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.

Update (2002/04/23): Windows users should download a new UNWISE.EXE from Wise that fixes a bug which could cause the uninstaller to disappear in some circumstances. Just drop it over the old uninstaller, which will be at C:\Python22\UNWISE.EXE unless you chose a different directory at install time.

Macintosh users can find binaries and source on the Mac page or Jack Jansen's MacPython page. (MacOS X users who have a C compiler can also build from the source tarball below.)

Red Hat Linux 7.3, 7.2 and 6.2 users can download RPMs, or build from source. An SRPM is also available for other RPM-based systems, or the source tar-file can be used (see the "rpm" man page for the "-ta" options).

All others should download Python-2.2.1.tgz, the source tarball, and do the usual "gunzip; tar; configure; make" dance.

What's New?

This being a bug-fix release, there have been no exciting new features implemented since 2.2 -- just heaps of fixes. For a partial list of these fixes, please see the release notes, or the Misc/NEWS file in the source distribution. For the full list of changes, you can poke around CVS.
