Hi all,

on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.3. You can download the sources and the Windows version from

http://www.zope.org/Products/Zope/2.8.3/

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 what is new in this release, see the CHANGES.txt files for the release:
