Zope 2.8.9.1 Released

This release corrects a bug introduced in one of the security fixes applied to release 2.8.9.

Announcing the Release of Zope version 2.8.9.1

On behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.9.1. You can download the sources and the Windows version from http://www.zope.org/Products/Zope/2.8.9.1/

This bugfix release corrects a problem introduced in 2.8.9, which prevented starting Zope in "background" / "daemonized" mode.

New features of Zope 2.8.x

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/)

Supported Python versions

At this time the only supported and recommended Python versions are 2.3.5 and 2.3.6.

Using Python 2.4.X is not supported and not recommended at this time. Python 2.4.X will be supported when a security audit takes place. This means that you are using Python 2.4 + Zope 2.8 at your own risk. This warning also applies to binary packages that install Zope packages together with a system wide Python 2.4 installation (e.g. Fedora, SuSE...). Such installations are in general not supported. In addition there some third-party products and Python packages that don't work with Python 2.4 and can cause trouble when using Python 2.4.
