Hi, Just wanted to make you aware of two excellent articles written by Martin Aspeli about the future of Plone and how we want to move forward and what roles the underlying technologies play — new and old: 1. http://martinaspeli.net/articles/pete-and-andy-try-plone-4 2. http://martinaspeli.net/articles/is-plone-too-hard Should be read in order, since the first one informs and sets the stage for much of what is discussed in the second one. -- Alexander Limi · http://limi.net

Zope 3.4.0 candidate 1 Released
by Stephan Richter 03 Feb '08

03 Feb '08

January 31, 2008 - The Zope 3 development team announces the Zope 3.4.0c1 release. This release is the first release candidate for Zope 3.4.0. It was preceeded by an early beta 2 release back in November, 2007. Zope 3.4 introduces support for binary large objects in the ZODB, and provides a new postprocessing hook for publishing results. Many of the packages also provide small feature improvements that are too numerous to list at this point. Packages and Eggs ----------------- Since the first Zope 3.4 alpha and beta releases, we have finished the transition to a completely egg-based system. This largely means that most Zope 3 developers do not use the classic Zope 3 tar ball release anymore. However, for your convenience, the Zope 3 developers will provide the classic Zope 3 tar ball releases for at least the 3.4 series and probably for 3.5 as well. So how are Zope 3 applications built using only eggs? The Known Good Set (KGS) ~~~~~~~~~~~~~~~~~~~~~~~~ The known good set -- or in short KGS -- is a package index that derives from the official Python Package Index (PyPI) and thus contains all available packages in the Python world. But for a controlled set of packages, only certain versions that are known to work together are available. The list of controlled packages and their versions for Zope 3.4 can be found at the index page [1]_. The index can be used in several ways -- described here for `buildout`-based projects. The easiest method is to specify the index option in your ``buildout.cfg`` file:: [buildout] index = http://download.zope.org/zope3.4 ... You can also "nail" the versions by downloading the versions [2]_ and insert them as follows: [buildout] versions = versions ... [versions] zope.interface = 3.4.0 ... ``zopeproject`` Project Builder ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Philipp von Weitershausen has developed a package called `zopeproject` to quickly setup the boilerplate for any Zope 3 based project. Ample documentation is provided at the `zopeproject` home page [3]_. `zopeproject` uses Paste or ZDaemon to create a working server. Here are the necessary commands to get a project started:: $ easy_install zopeproject $ zopeproject HelloWorld $ cd HelloWorld $ bin/helloworld-ctl foreground Demo Packages ~~~~~~~~~~~~~ At this point, there is no demo package demonstrating a simple Zope 3 application setup. (I hope one gets developed before Zope 3.4.0 final.) However, the ``z3c.formdemo`` package can be used as a fairly minimal setup. To get started with it, do the following:: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/tags/1.5.1 formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -v $ ./bin/demo fg .. [1] http://download.zope.org/zope3.4/controlled-packages.cfg .. [2] http://download.zope.org/zope3.4/versions.cfg .. [3] http://pypi.python.org/pypi/zopeproject What is Zope 3? --------------- Zope 3 is a web application server that continues to build on the heritage of Zope. It was rewritten from scratch based on the latest software design patterns and the experiences of Zope 2. The component architecture is the very core of Zope 3 that allows developers to create flexible and powerful web applications. Compatibility with Zope 2 -------------------------- Zope 3 is not upwards compatible with Zope 2. This means you cannot run Zope 2 applications in Zope 3. We continue to work on the transition from Zope 2 to Zope 3 by making Zope 2 use more and more of the Zope 3 infrastructure. This means that new code written in Zope 2 can benefit from Zope 3 technology. Also, with care, code can be written that works in both Zope 3 and Zope 2. This allows a Zope 2 application to slowly evolve towards Zope 3. Unchanged Zope 2 applications are never expected to work in Zope 3, however. Downloads --------- - Zope 3.4 Egg Index: http://download.zope.org/zope3.4 - Zope 3.4 Controlled Packages: http://download.zope.org/zope3.4/controlled-packages.cfg - Zope 3.4 Latest Versions: http://download.zope.org/zope3.4/versions.cfg - The classic Zope 3 source release can be downloaded from: http://zope.org/Products/Zope3 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 3.4 requires Python 2.4.4 to run. You must also have zlib installed on your system.

Since all contributions are now spread over a multitude of packages, listing all contributors is not feasible anymore.

The Foundation hasn't been hiding this effort, we just don't want too many cooks involved before it's ready. Anyway, Martin, I'm just recruiting people who want to write content for you and giving you people to add to your list of volunteers to write about Zope 3. I'm hoping you are keeping a list. :) Regards, Martijn
