db4o

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.
