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. Jeremy
