ALTER SEQUENCE and ALTER TABLE ALTER COLUMN RESTART can now be used inside a transaction.
Very large SELECT DISTINCT and UNION EXCEPT queries are now supported, however this feature is disabled by default. To enable it, set the system property h2.maxMemoryRowsDistinct to a lower value, for example 10000.
@changelog_1003_li
New system property h2.aliasColumnName. When enabled, aliased columns (as in SELECT ID AS I FROM TEST) return the real table and column name in ResultSetMetaData.getTableName() and getColumnName(). This is disabled by default for compatibility with other databases (HSQLDB, Apache Derby, PostgreSQL, some version of MySQL). In version 1.1 this setting will be enabled.
A error is now thrown when trying to call a method inside a trigger that implicitly commits the current transaction, if an object is locked.
@changelog_1004_li
When using encrypted databases, and using the wrong file password, the log file was renamed if the database was not already open. Fixed.
Unused LOB files were deleted much too late. Now they are deleted if no longer referenced in memory.

MVCC: now an exception is thrown when an application tries to change the MVCC setting while the database is already open.
@changelog_1125_li

Optimization for independent subqueries. For example, this query can now an index: SELECT * FROM TEST WHERE ID = (SELECT MAX(ID) FROM TEST) This can be disabled by setting the system property h2.optimizeSubqueryCache to false.
@changelog_1187_li
@changelog_1190_li
The explain plan now says: /* direct lookup query */ if the query can be processed directly without reading rows, for example when using MIN(indexed column), MAX(indexed column), or COUNT(*).

@changelog_1195_li
@changelog_1198_li
About 230 bytes per database was leaked. This is a problem for applications opening and closing many thousand databases. The main problem: a shutdown hook was added but never removed. Fixed.

@changelog_1205_li
@changelog_1208_li
Improved MultiDimension tool (for spatial queries): in the last few releases the tool was actually slower than using a regular query (because index lookup got faster, and because the tool didn't support prepared statements) Now the tool generates prepared statements, and the performance is better again (about 5 times faster for a reasonable amount of data).
@changelog_1206_li

@changelog_1211_li
@changelog_1214_li
The version number is now major.minor.micro where micro is the build number. Not all version are public, so there may be gaps in the micro. The minor changes when there is a file format change.
@changelog_1212_li
@changelog_1215_li
The backup tool (org.h2.tools.Backup) did not work. The restore tool did not work when the -db parameter was used. Fixed. The documentation of the backup tool has been changed: only one database may be backed up at any time.

@changelog_1224_li
@changelog_1227_li
The H2 Console can now connect to databases using JNDI. The driver class name must be a javax.naming.Context, (for example javax.naming.InitialContext), and the URL the resource name (for example java:comp/env/jdbc/Test). This should also work for linked tables.

The experimental H2 ODBC driver has been removed.
@changelog_1244_li
@changelog_1247_li
The default value for h2.defaultMaxMemoryUndo is now 50000. This avoids out of memory problems when using large transactions, however large transactions are slower because they are buffered to disk. To disable, use -Dh2.defaultMaxMemoryUndo=2000000000.
@changelog_1245_li
@changelog_1248_li

NCGC CurveFit
@links_1076_p
@links_1081_p
From: NIH Chemical Genomics Center, National Institutes of Health, USA. An open source application in the life sciences research field. This application handles chemical structures and biological responses of thousands of compounds with the potential to handle million+ compounds. It utilizes an embedded H2 database to enable flexible query/retrieval of all data including advanced chemical substructure and similarity searching. The application highlights an automated curve fitting and classification algorithm that outperforms commercial packages in the field. Commercial alternatives are typically small desktop software that handle a few dose response curves at a time. A couple of commercial packages that do handle several thousand curves are very expensive tools (&gt;60k USD) that require manual curation of analysis by the user; require a license to Oracle; lack advanced query/retrieval; and the ability to handle chemical structures.
