<h1>Change Log</h1>
<h2>Next Version (unreleased)</h2>
<ul><li>The built-in connection pool (JdbcConnectionPool) did not always honor the login timeout
<ul><li>CREATE FORCE VIEW didn't work in most cases if a referenced table didn't exist.
</li><li>MVCC: when trying to insert two rows with the same key from two connections,
the second connection immediately threw the exception "Unique index or primary key violation".
Instead, the second connection now waits throwing the exception until the first connection
committed the change (same as when trying to concurrently update the same row).
</li><li>Server mode: if the client ran with a different timezone setting than the server, date values
got shifted by the difference between the timezones. This problem affected the data types
DATE, TIME, and TIMESTAMP, when using PreparedStatement.setDate / setTime / setTimestamp
and ResultSet.getDate / getTime / getTimestamp.
To solve the problem, both the client and the server need to be updated (otherwise the old transfer protocol is used).
</li><li>The built-in connection pool (JdbcConnectionPool) did not always honor the login timeout
(the timeout could occur much too early). Thanks a lot to Dario Fassi for the patch!
</li><li>Translation: the new messages have been translated to Spanish. Thanks a lot to Dario Fassi!
</li><li>The table INFORMATION_SCHEMA.SETTINGS now contains all H2-specific system properties
