I'm pleased to announce the release of ZODB 3.4.2 final. This corresponds to the ZODB in Zope 2.8.2 final. You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.4 Note that there are two Windows installers, for Python 2.3 (2.3.5 is recommended) and Python 2.4 (2.4.2 is recommended). ZODB 3.4.2 mostly contains obscure error-case bugfixes relative to 3.4.1. One important fix: most applications that do subtransaction commits do so to reduce RAM consumed by the ZODB memory ("pickle") cache. When subtransactions were reimplemented on top of savepoints, this cache reduction no longer occurred. That was an oversight, and is repaired in 3.4.2. See the NEWS file for details: http://zope.org/Products/ZODB3.4/NEWS.html The current status of all active ZODB lines can be seen here: http://www.zope.org/Wikis/ZODB/CurrentStatus
