Zope 3 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.

It is our opinion that Zope 3 is more than ready for production use, which is why we decided to drop the X for experimental from the name. We will also continue to work on making the transition between Zope 2 and Zope 3 as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in the form of Five. This is a long term effort. We're not there yet. You can't run Zope 2 applications in Zope 3.

Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt file of the distribution. The binary installer is recommended for Windows.

Zope 3.2 requires Python 2.4.2 to run. You must also have zlib installed on your system.

Most Important Changes Since 3.2b1

New features

• Added an option to mkzopeinstance to create instances that use ZServer, rather than Twisted.
• Changed the way returning large results is handled. Applications can now simply return files to the publisher.

Bug Fixes

• Added input buffering to the twisted integration
• Fixed the plumbing in ZServer so that attempts to return large output efficiently using iterators can actually succeed.

For a complete list of changes see the CHANGES.txt file.
