Zope X3 3.0.0 final released

Stephan Richter writes “The Zope 3 development team is proud to announce Zope X3 3.0.0 final. After
almost three years of development it has finally arrived!

Zope X3 is the next major Zope release and has been written from scratch
based on the latest software design patterns and the experiences of Zope 2. The
“X” in the name stands for “experimental”, since this release does not try to
provide any backward-compatibility to Zope 2.

Zope is an open source web application server primarily written in the Python
programming language. It features a transactional object database which can
store not only content and custom data, but also dynamic HTML templates,
scripts, a search engine, and relational database (RDBMS) connections and
code. It features a strong through-the-web development model, allowing you to
update your web site from anywhere in the world. To allow for this, Zope also
features a tightly integrated security model. Built around the concept of “safe
delegation of control”, Zope’s security architecture also allows you to turn
control over parts of a web site to other organizations or individuals.

Zope users include Viacom, Boston.com, Lufthansa, SGI, AARP, Bell Atlantic
Mobile (now Verizon Wireless), Red Hat, NASA, the US Navy, ishophere.com,
i-Gift, IDG (Brazil), GE, Digital Garage, Verio, www.HireTechs.com, Park City
Ski Area, and Storm Linux.



Installation instructions for both Windows and Un*x/Linux are now available

  • On Windows, you must uninstall any previous installation of Zope X3 before
        installing the new release.

  • Zope X3 depends on zlib, which is usually compiled into
    Python by default, but if your system does not have the zlib
    library installed, it will skip to build the zlib module.

  • When creating the Zope 3 installation using the
        process, a few tests will sometimes fail, if you specify a relative
        prefix path. If this happens to you, just use the absolute
