<b>Changes and new functionality:</b>
<ul>
<li>New Console starter application uses the JDK 1.6 system tray
functionality if available, or a simple AWT frame for other platforms.
To try it out, execute java org.h2.tools.Console. Feedback is welcome.
This console starter application is not the default yet,
but the plan is to remove the SysTray tool in the future.
</li><li>If a Reader or InputStream of a LOB is not closed,
the LOB can not be deleted (embedded mode only). The exception is
typically ''Error while renaming file''). As a workaround, set the
system property ''h2.lobCloseBetweenReads'' to true to close the LOB
files between read operations. However this slows down reading.
</li><li>Views support has been partially re-implemented.
Views are up to 6 times faster. Compared to regular queries, only
20% overhead. Because this is a bigger change, it is not enabled
by default. To enable it, set the system property ''h2.indexNew''
to true (java -Dh2.indexNew=true ..., or in source code
Constants.INDEX_NEW = true). If no problems are found, this will
be enabled by default in the next release.
</li><li>Support for the data type CHAR. The difference to
VARCHAR is: trailing spaces are ignored. This data type is supported
for compatibility with other databases and older applications.
</li><li>Compatibility: Support for the data type notation
CHARACTER VARYING.
</li><li>File names starting with ~ are now in the user directory
(Java system property user.home)
</li><li>Can now ORDER BY -1 (meaning order by first column,
descending), and ORDER BY ? (parameterized column number).
</li><li>Linked tables can now emit UPDATE statements if
''EMIT UPDATES'' is specified in the CREATE LINKED TABLE statement.
So far, updating a row always deleted the old row and then inserted
the new row.
</li><li>New functions LEAST and GREATEST to get the smallest or
largest value from a list.
</li><li>For most IOExceptions now the file name is included in
the error message.
</li><li>New method Csv.write(Writer writer, ResultSet rs)
</li><li>The table id (important for LOB files) is now included in
INFORMATION_SCHEMA.TABLES.
</li><li>The aggregate function COUNT(...) now returns a long
instead of an int.
</li>
</ul>
<b>Bugfixes:</b>
<ul>
<li>In the last release, the H2 Console opened two connection
when logging into a database, and only closed one connection
when logging out. Fixed.
</li><li>In many situations, views did not use an index if they
could have. Fixed. Also the explain plan for views works now.
</li><li>Server mode: the server stack trace was included in
SQLException messages. Fixed.
</li><li>Databases with invalid linked tables (for example, because
the target database is not accessible) can now be opened. Old
table links don''t work however.
</li><li>In INSERT and MERGE statements, each column may
only be specified once now.
</li><li>A java.util.Date object is now converted to a TIMESTAMP
in the JDBC API. Previously it was converted to a DATE.
</li><li>After calling SHUTDOWN and closing the connection and
a superfluous error message appeared in the trace file. Fixed.
</li><li>When using DISTINCT, ORDER BY a function works now
as long as it is in the column list.
</li><li>The ''ordering'' of data types was not always correct,
for example an operation involving REAL and DOUBLE produced
a result of type REAL. Fixed.
</li><li>CSV tool: If the same instance was used for reading
and writing, the tool wrote the column names twice. Fixed.
</li><li>There was a small memory leak in the trace module.
One object per opened connection was kept in a hash map.
</li>
