Zope 2.8.0 released

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 the sources and the Windows version 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:

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. Backup your Data.fs before trying 2.8.0b2.

Please bring all the bugs you have found to the Zope bugtracker:
