[ZODB-Dev] ZODB4 alpha 2 release

[Jeremy Hylton]

We've released ZODB4 alpha 2, a snapshot of current progress on ZODB4. 
You can get it at http://www.zope.org/Products/ZODB4.

This release of ZODB4 contains all (or most) of the new features that
have been added to ZODB3 since the last ZODB4 alpha release.

This release contains the top-level persistence, transaction, zdaemon,
and zodb packages, as well as zope.interface and zope.testing.  The
implementation depends on zope.interface, but only in fairly limited
way.  The zope.testing package is only used by a few unit tests.
The zodb package includes FileStorage, two memory storages, two storages
based on BerkeleyDB, and ZEO, a client-server protocol for ZODB.

This will probably be the last ZODB4 release for a while, as we focus on
getting Zope3 into shape.
