+Zope 3.4.0 Released!
+====================
+
+January 29, 2009 - The Zope 3 development team announces the Zope 3.4.0 release.
+
+After 2 years of development, the Zope Foundation and the larger Zope
+community is proud to announce the release of Zope 3.4.0.
+
+The focus of the Zope 3.4 development was the conversion from one monolithic
+source tree to a set of many small packages (eggs) that can be used
+independently of each other. The core further stabalized through lots of bug
+fixes and many new add-on packages were developed to provide a richer
+development experience.
+
+With this release comes also renewed commitment to a short and reliable
+release cycle of 6 months.
+
+
+Packages and Eggs
+-----------------
+
+Zope 3 is now fully converted to an egg-based system. While some work still
+remains, it integrates in the best possible way with the rest of the Python
+community. The conversion to eggs also enables other Python developers to only
+use small bits and pieces of the complete Zope software. The conversion
+largely means that 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 configuration of packages and
+their versions that are known to work well together. The compatibility is
+frequently verified by running over twelve thousand tests on a daily
+basis [1]_. The KGS is tested against Python 2.4 and 2.5 on the 32- and 64-bit
+platforms. The list of controlled packages and their versions for Zope 3.4 can
+be found at the Zope 3 KGS site [2]_.
+
+The KGS can be used in several ways [3]_. The most common way is to "nail" the
+versions by downloading the version configuration file [4]_ and insert them as
+follows in your buildout configuration::
+
+  [buildout]
+  versions = versions
+  ...
+
+  [versions]
+  zope.interface = 3.4.0
+  ...
+
+
+``zopeproject`` Project Builder
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To start building a project using a common setup, a package called
+`zopeproject` can be used to quickly setup the boilerplate for the
+project. Ample documentation is provided at the `zopeproject` home page
+[5]_. `zopeproject` uses Paste or ZDaemon to create a working server. The
+following commands get you 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. However, the ``z3c.formdemo`` package can be used as a
+fairly minimal setup. To get started with it, enter the following::
+
+  $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/tags/1.5.3 formdemo
+  $ cd formdemo
+  $ python bootstrap.py
+  $ ./bin/buildout -v
+  $ ./bin/demo fg

+
+About 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.
+
+
+About the Zope Foundation
+-------------------------
+
+The Zope Foundation, based in Fredricksburg, Virginia, is a not-for-profit
+organisation that provides support for the Zope community and the Zope
+platform and its associated software. Its community includes the open source
+community of contributers as well as the community of businesses and
+organizations that use Zope.
