I'm pleased to announce the release of ZODB 3.5 final. This corresponds to the ZODB that will ship in Zope 3.1. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.5 Note that there are two Windows installers, for Python 2.3 (2.3.5 is recommended) and Python 2.4 (2.4.1 is recommended). ZODB 3.5 is very close to ZODB 3.4.1 in features. Subtransactions are deprecated in 3.5 (in favor of savepoints), and 3.5 adds a simple multi-database feature (a way to group multiple databases into a collection, such that a connection to any database in the collection can be used to obtain connections to the other databases in the collection). See the NEWS file for details: http://zope.org/Products/ZODB3.5/NEWS.html It's traditional to give a long list of ZODB releases and their corresponding Zope releases at this point. To save time, henceforth I'm going to point to ZODB's "current status" page instead: http://www.zope.org/Wikis/ZODB/CurrentStatus
