I am pleased to announce the third and final beta releases of ZODB3
and ZEO2.  These last beta releases were prompted by last minute
problems with ZEO signal handling and the FileStorage restore()
method.  See NEWS.txt and ZEO-NEWS.txt for details.

The final release will be on Friday.  Please give the betas a try
before then!
ZODB is an object database for Python that provides transactional
persistence while requiring few, if any, changes to application logic.
ZEO is a client-server storage system for ZODB.  The ZEO2 package is
released on its own and as part of ZODB3.  The separate release is for
Zope users, who already have ZODB.
You can get source releases from http://www.zope.org/Products/StandaloneZODB
and http://www.zope.org/Products/ZEO.  The ZODB3 release requires a C
compiler, while the ZEO2 release is pure Python.
The components you get with the ZODB3 release are as follows:
- Core ZODB, including the persistence machinery
- Standard storages such as FileStorage
- Supporting modules such as ExtensionClass
- The persistent BTrees modules
- ZEO (versions 1 and 2)
- Experimental Berkeley storages
- Updated documentation
The beta release contains roughly the same version of ZODB that was
included in Zope 2.6.  The two releases are not directly coordinated,
so there may be some subtle differences.
Many people have contributed to ZODB3.  Special thanks to Toby
Dickenson for the new ZODB Connection cache.  Many people at Zope
Corp. have contributed code and tested unreleased versions.
