Python 2.4.2

We are pleased to announce the release of Python 2.4.2 (final) on September 28, 2005.

Python 2.4.2 is a bugfix release of Python 2.4 - Python 2.4 is now in bugfix-only mode, no new features are being added. More than 60 bugs have been squashed since Python 2.4.1, including bugs that prevented Python working properly on 64 bit AIX and HP/UX. See the detailed release notes for more,

For more information on the new features of Python 2.4 see the 2.4 highlights or consult Andrew Kuchling's What's New In Python for a more detailed view.

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

Download the release

Starting with the Python 2.4 releases the Windows Python installer is being distributed as a Microsoft Installer (.msi) file. To use this, the Windows system must support Microsoft Installer 2.0. Just save the installer file Python-2.4.2.msi to your local machine, then double-click python-2.4.2.msi to find out if your machine supports MSI. If it doesn't, you'll need to install Microsoft Installer first. Many other packages (such as Word and Office) also include MSI, so you may already have it on your system. If not, you can download it freely from Microsoft for Windows 95, 98 and Me and for Windows NT 4.0 and 2000. Windows XP and later already have MSI; many older machines will already have MSI installed.

The new format installer allows for automated installation and many other shiny new features. There is also a separate installer Python-2.4.2.ia64.msi for Win64-Itanium users.

Windows users may also be interested in Mark Hammond's win32all package, available from Sourceforge. win32all adds a number of Windows-specific extensions to Python, including COM support and the Pythonwin IDE.

All others should download either python-2.4.2.tgz or python-2.4.2.tar.bz2, the source archive. The tar.bz2 is considerably smaller, so get that one if your system has the appropriate tools to deal with it. Unpack it with tar -zxvf Python-2.4.2.tgz (or bzcat Python-2.4.2.tar.bz2 | tar -xf -). Change to the Python-2.4.2 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.
