     * Deferrable constraints - Constraint enforcement can now be 
deferred, typically to the end of a transaction.
     * WHEN clause in CREATE TRIGGER - An optional WHEN clause has been 
added which determines which rows fire a trigger.
     * Rolling log file - The Derby diagnostic log can now be split 
across a sequence of files.
     * Experimental Lucene support - Derby text columns can now be 
indexed and queried via Apache Lucene.
     * Simple case expression - The "simple" and "extended" syntax for 
CASE expressions has been added.
     * Better concurrency for identity columns - The concurrency of 
identity columns has been boosted.
     * New ij HoldForConnection command - A new ij command has been 
added to change the default cursor holdability.
     * Standard syntax for altering column nullability - Standard syntax 
has been added for altering the nullability of columns.

In addition, Derby contains many bug, security, and 
documentation fixes.
