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

Changes

User defined aggregate functions are not supported. The CSV tool has been improved. Linked tables in non-default schemas are now supported. The Console application was translated to Italian. Stack traces with SQL statements are now shorter. Problems with prepared statements and XA connections have been fixed.
