ZODB 3.4.2 final released

[Tim Peters]

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:
