Zope 2.2.1 beta 1 has been released - you can download it from

This release contains many bug fixes, including the fix for the recently announced security issue. It also includes fixes to the ZODB code for supporting object databases over 2GB (provided your platform supports large files).

For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release:

Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.2.x site. These updates are available for those currently using the 2.2.x source release or the 2.2.x binary releases for either solaris or linux.

To apply a differential update to your site:

  • download the appropriate .tgz file from
  • shutdown your Zope process
  • copy the .tgz to your Zope directory and extract it
  • run w_pcgi or wo_pcgi if you are not using a binary release
  • restart your process
