<h2>Version 1.2.131 (2010-03-05)</h2>
<ul><li>Older versions of H2 (version 1.2.127 and older) could not connect to a new version (version 1.2.129 and newer).
The connection blocked when trying to connect. Now the connection no longer blocks, instead a SQL exception is thrown.
</li><li>In versions 1.2.129 and 1.2.130, a database could not be opened sometimes
after dropping tables or indexes, and then creating new indexes for existing tables.
The exception contained the text "parent not found" (version 1.2.129) or
The exception contained the text "parent not found" (version 1.2.129) or
"Table not found" (version 1.2.130).
</li><li>After the database was closed, a null pointer exception could occur in Database.flush.
</li><li>An IndexOutOfBoundsException could occur in the page store (eg. on "delete from table"). Fixed.

<h2>Version 1.1.110 (2009-04-03)</h2>
<ul><li>Support for not persistent in-memory tables in regular (persistent) databases
using CREATE MEMORY TABLE(..) NOT PERSISTENT. Thanks a lot to Sergi Vladykin for the patch!
</li><li>The H2 Console trimmed the password (removed leading and trailing spaces).
This is no longer the case, to support encrypted H2 database with an empty user password.
</li><li>The data type of a SUBSTRING method was wrong.
</li><li>ResultSet.findColumn and get methods with column label parameters
now also check for matching column names (like most databases except MySQL).
</li><li>H2 Console: the browser system property now supports a list of arguments.
Example: java -Dh2.browser="open,-a,Safari,%url" ...
</li><li>Improved Javadoc navigation (similar to Scaladoc).
</li><li>H2 Console: auto-complete of identifiers did not work correctly
for H2 databases in MySQL mode.
</li><li>DISTINCT and GROUP BY on a CLOB column was broken.
</li><li>The FTP server moved to the tools section and is no longer included in the h2*.jar file.
</li><li>Improved error message for unsupported features:
now the message says what exactly is not supported.
</li><li>Improved OSGi support.
</li><li>Some internal caches did not use the LRU mechanism. Fixed
(LOB file list, optimizer cost cache, trace system, view indexes, collection keys,
compressed in-memory file system).
</li><li>The API of the tools changed a bit (each tool now returns an exit code).
</li><li>Command line help of the tools now match the javadocs.
The build converts the javadocs to a resource that is read by the tool at runtime.
This should not have an effect on using the database, but it reduces duplicate
and out-of-sync documentation.
</li><li>CREATE TABLE: improved compatibility (support for UNIQUE NOT NULL).
</li><li>DatabaseMetaData.getSQLKeywords now returns the correct list.
</li><li>Deterministic user defined functions did not work when the parameter was a column. Fixed.
</li><li>JdbcConnectionPool.setLoginTimeout with 0 now uses the default timeout.
</li><li>Creating a JdbcConnectionPool has been simplified a bit.
</li><li>The built-in connection pool did not re-use connections.
Getting a connection using the built-in JdbcConnectionPool is now about 70 times faster
than opening connections using DriverManager.getConnection.
</li><li>More bugs in the server-less multi-connection mode have been fixed:
If a process terminated while writing, other open connections were blocked.
If two processes were writing to the database, sometimes the database was corrupt after closing.
</li><li>Linked tables to SQLite database can now be created.
</li><li>Nested IN(IN(...)) didn't work.
</li><li>NIO storage: the nio: prefix was using memory mapped files instead of FileChannel.

</li><li>Tree index: Instead of an AVL tree, use a general balanced trees or a scapegoat tree.
</li><li>User defined functions: allow to store the bytecode (of just the class, or the jar file of the extension) in the database.
</li><li>Compatibility: ResultSet.getObject() on a CLOB (TEXT) should return String for PostgreSQL and MySQL.
</li><li>Optimizer: WHERE X=? AND Y IN(?), it always picks the index on Y. Should be cost based.
</li><li>Support ALTER SCHEMA name RENAME TO newname (rename schema).
</li><li>Optimizer: WHERE X=? AND Y IN(?), it always uses the index on Y. Should be cost based.
</li><li>Support ALTER SCHEMA name RENAME TO newName (rename schema).
</li><li>Make the cache scan resistant (currently a small cache is faster than a large cache for large table scans).
</li></ul>
