Berkeley DB Java Edition (JE) 3.3.62 is now available for download at http://www.oracle.com/technology/software/products/berkeley-db/je/index.html
. The release contains new features and bug fixes, many in response to
questions and requests from users. Thanks to all for your
help in reporting problems, describing use cases, and patiently waiting
for features to appear.

There's improvements in performance, cache management and memory and disk space utilization. Highlights include:

* Multiple JE environments can now share the same cache to make better use of memory.

* The deferred write mode can be configured to differentiate between
truly temporary databases and databases which should be persistent.
* Key prefixing.
* Better cache management for large numbers of databases.
* Per operation caching policy.
* Performance improvements.

Note
that JE 3.3.62 introduces a forward-compatible on-disk file format
change from JE 3.2. And for the first time, this release introduces a
binary and API incompatibility that will hopefully affect few of you.
