6.1

此版本配备了一个改进的客户机/服务器协议，目前已经完全同步，并能够批量邮件。这两个变化减少客户数/服务器消息往返，从而提高客户机/服务器的性能。
标签: Development, Minor feature enhancements
This release comes with an improved client/server protocol, which is now completely asynchronous and able to batch messages. Both changes reduce the number of client/server message round trips, and therefore improve client/server performance.

6.0

此版本带有一个新的BTree结构和主要性能增强的一个新的查询结果处理器上运行的新BTrees。确定性实时查询响应成为可能使用新的“懒惰查询评价”算法。
标签: Java, Major feature enhancements
This release comes with a new BTree architecture and major performance enhancements resulting from a new query processor that runs on the new BTrees. Deterministic immediate query responses were made possible using a new "Lazy Query Evaluation" algorithm.

5.5

此版本是一个性能版本。它使用了类的一个新的BTree索引结构，以减少时间，即急剧增加。对字符串和数组插入新marshallers改善和更新实现更好的时段集群的性能。阿包新的诊断提供了更多的发展商的协助，以快速发展的应用程序。各项性能的改善也可能导致内存消耗低，强调db4o的嵌入式低ressource系统使用的适用性。
标签: .NET, Major feature enhancements
This release is a performance release. It uses a
new BTree architecture for class indexes to reduce
the time for commits dramatically. New marshallers
for strings and arrays improve insert and update
performance by achieving a better clustering of
slots. A new diagnostics package provides more
help for developers to develop fast applications.
All performance improvements also lead to a lower
memory consumption, emphasizing db4o's suitability
for embedded use on low ressource systems.
