[Zope] Zope 2.8.4 released

[Andreas Jung]

Hi all,

on behalf of Zope Corporation and the Zope community I am pleased to 
announce the release of Zope 2.8.4.  You can download Zope 2.8.2 from

      http://www.zope.org/Products/Zope/2.8.4/

This version obsoletes Zope 2.8.2 and Zope 2.8.3 which shipped with an
older Docutils version as expected. For security reasons you should update
to Zope 2.8.4. In addition this release fixes a potential security problem
when using Zope with Python 2.4 - although Python 2.4. is neither
recommended nor supported. This release does *not mean* that Python 2.4 is
from now on supported but there are already installation using Python 2.4 
(mostly because modern Linux distributions ship with Python 2.4 and Zope 
usually uses the system-widePython installation).

Some new features of Zope 2.8:

   - ZODB 3.4 with MVCC (multi version concurrency control) support.
     MVCC solves nearly every problem with ZODB read-conflict errors
     which is very important for high-traffic Zope sites.

   - Extension Classes were rewritten as Python new-style classes making
     all features of Python new-style classes available in Zope
     objects. This includes support for cyclic garbage collection.

   - Integration of Zope 3 technologies through Five (see 
http://codespeak.net/z3/five/)

For more information on the available Zope releases, guidance for selecting
the right distribution and installation instructions, please see:

Please also keep in mind that Zope 2.8.4 requires Python 2.3.5. Zope 2.8.4
is not certified for any Python 2.4.x versions. So using Python 2.4 is 
neither recommended nor supported and any related questions or problems are 
likely to be ignored until 2.4 is an officially supported Python version 
for Zope.
