</li></ul>
<h2>Version 1.0.79 (2008-09-26)</h2>
<ul><li>Linked tables that point to the same database can now share the connection
within the same database. Access to the same connection is serialized. To enable this feature,
set the system property h2.shareLinkedConnections to true.
</li><li>Multiple processes can now access the same database without having to explicitly
start the server. To do that, append ;AUTO_SERVER=TRUE to the database URL.
In this case, the server is started automatically if the connection is in embedded mode,
and the server mode is used if a server is running. If the process that opened the first
connection is closed, the other client need to reconnect (there is no automatic re-connect so far).
Remote connections are allowed, but only to this database.
</li><li>The server tool now displays the correct IP address if networked.
</li><li>Can now start a TCP server with port 0 (automatically select a port).
</li><li>Result sets with just a unique index can now be updated (previously a primary key was required).
</li><li>LINKED TABLE: the schema name can now be set. When multiple tables exist in different schema,
and the schema name is not set, an exception is thrown.
</li><li>LINKED TABLE: worked around a bug in Oracle with the CHAR data type.
</li><li>Faster hash code calculation for large binary arrays.
</li><li>Faster storage re-use algorithm thanks to Greg Dhuse from cleversafe.com.
</li><li>The database supports the SHOW command for better MySQL and PostgreSQL compatibility.
</li><li>The H2 Console now abbreviates large texts in results.
</li><li>Multiple UNION queries could not be used in derived tables.
</li><li>Linked tables can now be read-only.
</li><li>Temporary linked tables are now supported.
</li><li>It was possible to create tables in read-only databases.
</li><li>SET SCHEMA_SEARCH_PATH is now documented.
</li><li>SET SCHEMA did not work for views.
</li><li>Row level locking for MVCC is now enabled. The exception
'Concurrent update in table ...' is still thrown, but only after the lock timeout.
</li><li>The maximum log file size setting was ignored for large databases.
</li><li>Multi-Version Concurrency (MVCC) may no longer be used when using
the multi-threaded kernel feature (MULTI_THREADED). An exception is thrown
when trying to connect with both settings. Additional synchronization
is required before those features can be used together.
</li><li>The data type JAVA_OBJECT could not be used in updatable result sets.
</li><li>The system property h2.optimizeInJoin did not work correctly.
</li><li>Conditions such as ID=? AND ID &lt; ? were slow.
</li></ul>
<h2>Version 1.0.78 (2008-08-28)</h2>
<ul><li>The documentation no longer uses a frameset (except the Javadocs).
</li><li>When using DB_CLOSE_DELAY, sometimes a NullPointerException is thrown when
the database is opened almost at the same time as it is closed automatically.
Thanks a lot to Dmitry Pekar for finding this!
</li><li>Java methods with variable number of parameters can now be used (for Java 1.5 or newer).
</li><li>The Japanese translation has been improved by Masahiro Ikemoto. Thanks a lot!
</li><li>The H2 Console replaced an empty user name with a single space.
</li><li>The build target 'build jarSmall' now includes the embedded database.
</li><li>JdbcDataSource now keeps the password in a char array where possible.
</li><li>ResultSet.absolute did not always work with large result sets.
</li><li>Column aliases can now be used in GROUP BY and HAVING.
</li><li>Jason Brittain has contributed MySQL date functions. Thanks a lot!
They are not in the h2.jar file currently, but in src/tools/org/h2/mode/FunctionsMySQL.java.
To install, add this class to the classpath and call FunctionsMySQL.register(conn) in the Java code.
</li></ul>
<h2>Version 1.0.77 (2008-08-16)</h2>
<ul><li>JaQu is now using prepared statements and supports Date, Time, Timestamp.
</li><li>When using remote in-memory databases, large LOB objects did not work.
</li><li>Timestamp columns such as TIMESTAMP(6) were not compatible to other database.
</li><li>Opening a large database was slow if there was a problem opening the previous time.
</li><li>NOT IN(SELECT ...) was incorrect if the subquery returns no rows.
</li><li>CREATE TABLE AS SELECT did not work correctly in the multi-version concurrency mode.
</li><li>Support a comma before closing a list, as in: create table test(id int,)
</li><li>MySQL compatibility: linked tables had lower case column names on some systems.
</li><li>DB2 compatibility: the DB2 fetch-first-clause is supported.
</li><li>Oracle compatibility: old style outer join syntax using (+) did work correctly sometimes.
</li><li>ResultSet.setFetchSize is now supported.
</li><li>It has been reported that when using Install4j on some Linux systems and enabling the 'pack200' option,
the h2.jar becomes corrupted by the install process, causing application failure.
A workaround is to add an empty file h2.jar.nopack next to the h2.jar file.
The reason for this problem is not known.
</li></ul>
<h2>Version 1.0.76 (2008-07-27)</h2>
<ul><li>The comment of a domain (user defined data type) is now used as the
default column comment when creating a column with this domain.
</li><li>Invalid database names are now detected and a better error message is thrown.
</li><li>ResultSetMetaData.getColumnClassName now returns the correct
class name for BLOB and CLOB.
</li><li>Fixed the Oracle mode: Oracle allows multiple rows only where
all columns of the unique index are NULL.
</li><li>There is a problem with Hibernate when using Boolean columns.
A patch for Hibernate has been submitted at
http://opensource.atlassian.com/projects/hibernate/browse/HHH-3401
</li><li>ORDER BY on tableName.columnName didn't work correctly if the column
name was also used as an alias.
</li><li>H2 Console: the progress display when opening a database has been improved.
</li><li>The error message when the server doesn't start has been improved.
</li><li>Key values can now be changed in updatable result sets.
</li><li>Changes in updatable result sets are now visible even when resetting the result set.
</li><li>Temporary files were sometimes deleted too late when executing large insert, update,
or delete operations.
</li><li>The database file was growing after deleting many rows, and after large update operations.
