I'm pleased to announce the release of ZODB 3.2.4 (final). This corresponds to the ZODB (and ZEO) that shipped with Zope 2.7.3 (final). You can download a source tarball or Windows installer from: http://zope.org/Products/ZODB3.2 Note that 3.2.4 incorporates a major change in semantics: it's incorrect to attempt to close a connection when objects from that connection are still in a modified state, and 3.2.4 raises the new ConnectionStateError exception in such cases. 3.2.4 also incorporates a significant ZEO performance fix, and a number of smaller bugfixes. See the news file for details: http://zope.org/Products/ZODB3.2/NEWS Note that ZODB 3.2.4 does not support Zope 2.7.2, because the Zope 2.7.2 publishing subsystem is an example of application code that didn't always finish a transaction before closing connections. ZODB 3.2.4 can be used with Zope 2.7.3. Note that ZODB 3.2.4 does not support Zope X3 or Zope 2.8 (they require ZODB 3.3).
