Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.0a1. You can download the sources and the Windows version from http://www.zope.org/Products/Zope/2.8.0a1/ Some new features of Zope 2.8: - Zope 3.3 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. For more information on what is new in this release, see the CHANGES.txt files for the release: http://www.zope.org/Products/Zope/2.8.0a1/CHANGES.txt WARNING: the 2.8.0a1 is not thought for production purposes. Use this version for development and evaluation only. 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 (ZClasses are currently broken). Backup your Data.fs *before* trying 2.8.0a1. Please bring all the bugs you found to the Zope bugtracker at http://collector.zope.org/Zope For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.plope.com/Books/2_7Edition/InstallingZope.stx Thanks to everyone having contributed to this release. Special thanks to Jim Fulton for his work on the migration of Extension Classes and to Tim Peters and Jeremy Hylton for their work on ZODB 3.3. -- Andreas Jung (andreas at zopyx dot com)
