Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.0. You can download Zope 2.8.0 from http://www.zope.org/Products/Zope/2.8.0/ 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: http://www.zope.org/Products/Zope/2.8.0/CHANGES.txt See also: http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView **WARNING:** Due to the major changes in Extension Classes and ZODB there is a risk that some things are broken or do not work as they should.
