<h2>Version 1.2.123 (2009-11-08)</h2>
<ul><li>Page store: new databases can not be opened with older versions.
</li><li>Page store: updating large rows (rows with more than 2000 bytes of data)
could corrupt the database.
</li><li>Page store: inserting very large rows failed with ArrayIndexOutOfBoundsException.
</li><li>When using multi-threaded kernel mode, setting disabling locking (LOCK_MODE=0)
will now throw an exception. At this time this combination will result in corruption when
multiple threads try to update the same table.

</li><li>Improved error messages: identifiers and values are now quoted.
</li><li>Improved error message when casting a value failed:
the column name and type is included in the message.

<h2>Version 1.1.102 (2008-10-24)</h2>
<ul><li>The French translation of the H2 Console has been improved by Olivier Parent.
Thanks a lot!
</li><li>There was a memory leak when creating and dropping tables and
indexes in a loop (persistent database only).
</li><li>SET LOG 2 was not effective if executed after opening the database.
</li><li>Translating the H2 Console is now simpler.
</li><li>Common exception (error code 23*) are no longer written to the .trace.db file by default.
</li><li>In-memory databases don't write LOBs to files any longer.
</li><li>Self referencing constraints didn't restrict deleting rows that reference
itself if there is another row that references it.
</li><li>ResultSetMetaData.getColumnName now returns the alias name except for columns.
</li><li>Temporary files are now deleted when the database is closed, even
if they were not garbage collected so far.
</li></ul>
<h2>Version 1.1.101 (2008-10-17)</h2>
<ul><li>Errors with code 42000 - 42999 are no longer written to the trace file by default.
</li><li>Queries with more than 10 tables are now faster.
</li><li>Opening a connection with AUTO_SERVER=TRUE is now fast
when the database is already open in another process (less than 0.01 seconds
instead of 2 seconds).
</li><li>IF [NOT] EXISTS is supported for named constraints in
ALTER TABLE ... ADD/DROP CONSTRAINT.
</li><li>The error messages have been translated to Spanish by Dario V. Fassi.
Thanks a lot!
</li><li>Linked tables: the automatic connection sharing didn't work. Actually the
system property h2.shareLinkedConnections was working in the opposite direction:
it was disabled when set to true. Now it works as expected.
</li><li>Opening large database is now faster.
</li><li>New system property h2.socketConnectTimeout, the timeout in milliseconds
to connect to a server. The default is 2000 (2 seconds).
</li><li>The wrong parameters were bound to subqueries with parameters, specially
when using IN(SELECT ...) and IN(...).
</li><li>Unset parameters were not detected when the query was re-compiled.
</li><li>New functions ISO_YEAR, ISO_WEEK, ISO_DAY_OF_WEEK.
Thanks a lot to Robert Rathsack for implementing those!
</li><li>The date functions DAYOFYEAR, DAYOFMONTH, DAYOFWEEK are now called
DAY_OF_YEAR, DAY_OF_MONTH, DAY_OF_WEEK (the old names still work).
</li><li>An out of memory error while deleting or updating many rows could
result in a strange exception.
</li><li>Linked tables: compatibility with MS SQL Server has been improved.
</li><li>Renaming tables that have foreign keys with cascade didn't work correctly.
</li><li>The auto-reconnect feature didn't work when using the auto-server mode. Fixed.
</li><li>Fulltext search: new method FT_DROP_INDEX.
</li><li>The optimization to group using an index didn't work in some cases in version 1.1
(see also system property h2.optimizeGroupSorted).
</li><li>OSGi meta data is included in the manifest file.
An OSGi BundleActivator is included: it loads the database driver when starting the bundle,
and unloads it when stopping the bundle.
</li><li>The default value for MAX_MEMORY_UNDO is now 50000.
</li><li>For alias columns, ResultSetMetaData.getTableName() and getColumnName() now
return the real table and column name in the default mode.
</li><li>In SQL scripts created with SCRIPT TO, schemas are now only created if they don't exist yet.
</li><li>After re-connecting to a database, the database event listener (if set) is informed about it.
</li><li>Local temporary tables now support indexes. Thanks a lot to Matt Roy!
</li><li>RUNSCRIPT no longer uses a temporary file.
</li><li>New system table INFORMATION_SCHEMA.SESSION_STATE containing the
SQL statements that make up the session state. The list currently contains
variables (SET @..) and local temporary tables (without data).
</li><li>After an automatic re-connect, part of the session state stays (the part
that is stored in the SESSION_STATE table).
</li><li>The build didn't work if the directory temp didn't exist before.
</li><li>New system property h2.maxReconnect (default 3) to limit the number of re-connects
for the same SQL statement (this is usually only important for SHUTDOWN).
</li><li>WHERE .. IN (SELECT ...) could throw a NullPointerException.
</li><li>Improved Glassfish / Toplink support in H2Platform
thanks to Marcio Borges from Brazil. Thanks a lot!
</li></ul>
<h2>Version 1.1.100 (2008-10-04)</h2>
<ul><li>In version 1.1, the following system properties are now enabled by default:
h2.lobFilesInDirectories, h2.optimizeGroupSorted, h2.optimizeInJoin, h2.shareLinkedConnections
</li><li>The H2 Console tool now works with the JDBC-ODBC bridge.
</li><li>The H2 Console tool now supports command line options to start things separately.
</li><li>Large objects did not work for in-memory databases in server mode in Linux.
</li><li>Connections from a local address other than 'localhost' were not allowed if remote
connections were disabled. This was always a problem, but only got visible in the last release
because the server no longer connects to 'localhost' if networked.
</li><li>The h2console.war can now be built using the Java build.
</li><li>By default, databases are shared in the same process. For read-only databases
this causes unnecessary synchronization, but safes memory. If you want that each connection
opens its own database, append ;OPEN_NEW=TRUE to the database URL.
</li><li>New auto-reconnect feature will cause the JDBC driver to reconnect to
the database if the connection is lost. To enable, append ;AUTO_RECONNECT=TRUE to the database URL.
This is specially helpful when using AUTO_SERVER. AUTO_SERVER automatically uses auto-reconnect.
</li><li>CreateCluster: the property 'serverlist' is now called 'serverList'.
</li><li>The ConvertTraceFile tool could not parse some files because the trace
mechanism did not encode prepared statement parameters.
</li><li>Databases names can now be one character long
(the minimum size used to be 2 characters).
