H2 is an SQL database engine written in Java that implements the JDBC API. Embedded, server, and clustering modes are available. A browser based console application is included. The database has strong security features. Disk based and in-memory databases and tables are supported


The JaQu (Java Query) tool is now using prepared statements and supports date, time, and timestamp. A comma before closing a list is supported, as in, "create table test(id int,)". ResultSet.setFetchSize is now supported. The compatibility with MySQL, DB2, and Oracle has been improved.
