    Release Notes: This release adds a new TRAVERSE command to traverse records by relationships, a new fetch plan to support more complex use cases, an asynchronous API to speed inserts, updates, and deletes via a remote network, a new DECIMAL type to handle currency without the pains of float and double types, a strict schema mode to work like a Relational DBMS, resolution of the "big-node" problem when a record has many links to other records by using an MVRB-Tree to handle relationships, new NOT and INSTANCEOF operators for SQL, an index which works against MAP types, support for JPA @Embedded annotation, and bugfixes for 54 issues.

          Release Notes: The new SQL [] operator was added to extract items from lists, sets, maps, and arrays. ORDER BY works with projection alias. Cross trees and graphs in projections. The IN operator uses Index when available. All known bugs on transaction recovery were fixed. The memory management of MVRB-Tree was rewritten to be faster and to use much less RAM. The common and core modules are compatible with Java 5.

                Release Notes: Multi-thread problems were fixed. Index searching was mad faster. The SQL BETWEEN operator was added. The SQL ALTER CLASS and ALTER PROPERTY commands were added to refactor the db schema. Console DROP DATABASE and INDEXES commands were added. The DATE type was added to handle dates only with YYYY/MM/SS. The SQL distinct(), union(), intersect(), and difference() functions were added. MVCC (Multi-version Concurrency Control) system is enabled also outside transactions by default, but can be turned off. The +, -, *, /, and % math operations are supported in an SQL query. Security checks are enforced. The core is compatible with Java5, while the server needs Java6.

                  Release Notes: A new defragmentation algorithm is used to reduce holes and therefore disk space consumption. A very fast implementation of lazy collections that optimizes marshalling/unmarshalling is now used. The HTTP protocol now handles multipart requests. HTTP Download and Upload commands were added. Problems with cluster configuration when multiple databases were opened were fixed. Eight new configuration parameters were added. The OLockManager class was added to lock at the record level. Many bugs were fixed.
