CPS 3.4.0 released!

After 1 year and 1/2 of hard work (more than 11000 commits by 32 developers),
Nuxeo is pleased to announce, on behalf of the CPS developers community, the
release of CPS 3.4.0, the new stable version of CPS, the open source ECM

Source code is available here:

A binary installer for Windows (includes Zope 2.9.1) here:

And other binaries are planned for release in a few days (including MacOS).

Please read the following for more information on CPS and CPS 3.4.

What is CPS?

CPS is an Open Source Enterprise Content Management (ECM) platform that
provides developers with a rich toolkit to create applications in the fields
of: Web Content Management (WCM), Document Management (DM), Collaboration
(CSCW), Workflow and Business Process Management (BPM) and corporate portals.

CPS may be compared to proprietary solutions like Documentum by EMC,
LiveLink by OpenText, or SharePoint by Microsoft.

What's new?

A lot of things have changed since the previous major stable release, CPS 3.2,
in september 2004. Here are the most important ones.

User-visible changes

1. A new default UI, that features both usability improvement and a
   better-looking default skin. This makes working with CPS a more enjoyable
   experience for end-users.

2. Switch from HTML 4.01 Transitional to XHTML 1.0 Strict, with work
   on accessibility (A-level by default, AA and AAA-level possible at the
   expense of some features).

3. AJAXification: use of AJAX techniques for a more responsive and more
   powerful UI (asynchronous form updates).

4. CPSSkins, which is a very powerful web-based WYSIWYG theme editor for
   CMF-based applications, has been integrated. It makes it easy for graphic
designers or webmasters to modify the look of CPS without writing CSS or template code. 5. CPSPortlets, a web-based WYSIWYG portlet editor that makes it easy for
   content administrators to modify the presentation of information on
   a CPS site.

6. New applicative products have been added to the CPS default application: CPSBlog (for blogs), CPSWiki (for wikis), CPSOOo (to manage

7. The webmail and shared calendar components have been completely rewritten.
   They are available as separate packages.

8. CPSGeo, a GIS product for CPS that allows for geolocation of documents in a
   CPS application. It is available as a separate package.

Architecture changes

1. We have switched to recent versions of Zope (2.9) and CMF (1.6).

2. We have switched most new developments to the Zope 3 component architecture,
   thanks to Five, the bridge between Zope 2 and Zope 3.

3. We now use of GenericSetup, the new "default", XML-based, configuration
   tool, instead of CPSInstaller. Using declarative configuration makes it now
   much easier to manage upgrades between versions

4. We have switched the unit and functional test harnesses to the Zope 2.9
   layer-based test runner. This eases the creation and speeds up the execution
   for the 2543 tests included in the CPS source code so far.

5. We now use CPSUserFolder as a powerful replacement to UserFolder.
   CPSUserFolder makes it possible to use a user directory managed by
   CPSDirectory as a source of users in CPS.

6. DCWorkflow has been extended as CPSWorkflow to provide a document-based
   workflow engine with dynamic schemas support (inspired by the activity-based
   workflow model) that can handle any document-based business process. This
   hybrid model gives all the power and flexibility needed to define dynamic
   validation / review / delegation states to model any paper process you have
   in the real world, while keeping workflow modeling simple enough to be
   easily understood by users.

7. CPSRemoteController provides a Web Service interface to remotely control
   CPS portals (both from another CPS portal or from totally different
   applications) in a language-independent manner through XML-RPC.
CPSRemoteController is also very handy for task automation.
8. CPSRelation provides a tool that manages RDF relations between content

9. Many, speed optimisations, at both low level (including work on ZODB
   transactions and CPSCore internal optimizations) and high level (rendering
   of CPSDocument and CPSPortlets caches) to make it possible to manage
   applications with hundreds of thousands of documents (soon: millions of
   documents) and tens of gigabytes of data (soon: terabytes of data).

Packaging changes

CPS is now distributed as several packages.

- "CPS Platform": the ECM platform. It embeds all the infrastructure components
  that are needed to develop ECM applications. The primary audience for CPS
  Platform is developers.
- "CPS": the application. A standard full-featured content management
  application based on CPS Platform, that features a rich set of default
  content types, a blog, a wiki and a forum. The primary audience for CPS
  Platform is people that want to try out CPS, as well as internet or intranet
  sites administrators with minimal customisation needs.
  CPS is available both as source code packages, and binary installers for
  several popular platforms (including MS-Windows).
- "CPS Legacy": a set of old components which are either deprecated or
  currently unmaintained. These components are needed to upgrade older versions
  of CPS.  The primary audience for CPS Legacy: internet or intranet sites
  administrators who need to upgrade old instances of CPS.

More information

An updated document "What's new in CPS 3.4", as well as more information like
tutorials and screencasts, will be published on in
the upcoming days.

Prerequisites to installation

Zope 2.9 is mandatory for installation from the source code.

Some third-party Python librairies may also be needed, depending on the
components you will want to activate on instanciation.

For more information, check:


In any case, DON'T DO THIS ON A PRODUCTION SITE. Make backups first, or run the
procedure on a copy.

If you are running a recent version of CPS, go to portal_setup at the root of
your CPS (from the ZMI) and see, from the "Upgrades" tab, if some upgrades need
to be run.

If you are running an older version (no portal_setup), start by adding a "CPS
Setup Tool" (not a "Generic Setup Tool") from the "CPS Tools" ZMI menu item,
before running the upgrades.

Upgrades have not been tested from every possible version, and some work,
that is planned for CPS 3.4.1, is needed to cover all the major cases.

For more information on upgrades, please join one of the CPS users mailing
lists (see below) or wait for further information that will be published on

About CPS

CPS is the most advanced Open Source Enterprise Content Management (ECM)

It is based on the Zope application server, the CMF content management
framework, is the result of important CMS, ECM and workflow projects carried
out in the public administration and the private sector, and of the
collaboration of dozens of open source developers.

Getting involved

Please join the CPS users, developers or translators mailing list on

Please report issues or requests for enhancements ont the CPS trac at:

If you'd like to add a translation to your native language, besides the current
11 ones (en, fr, de, it, es, pt_br, es, ro, mg, eu, ml), or to improve an
existing one, we welcome your contribution.

The future roadmap for CPS will be discussed on the cps-devel mailing list.


On behalf of the CPS core development team, I'd like to express our gratitude
to all the people that have been involved in this process (core and casual
developers, testers, documentation authors, translators, etc.), and to the
Python / Zope / CMF developers communities that make our work possible.

Special thanks to all the CPS customers, because CPS development is driven by
the projects that are actually using it.


*Q*: Is CPS really open source? Aren't there any proprietary extensions that
are sold on top of the platform?

*A*: CPS is 100% open source / free software. You can use it, modify it and
redistribute it, under the terms of the GPL license. We (Nuxeo) don't sell
licenses, only support and develop customers projects on top of CPS Platform.
And if you are a free software developer, you are very welcome to join the
project as a tester, bugfixer, third-party product developer or core developer.
