     <section name="Release notes for Commons-DBCP 1.1">
There were a lot changes since the 1.0 release on 12 Aug 2002.
<li>All existing features can now be configured by JNDI Context providers (Tomcat)
<li>The double close() of a pooled connection is more effectively blocked
  (you may experience more "Already closed" SQLExceptions)</li>
<li>Prepared statement pooling is now implemented in BasicDataSource
  (set poolPreparedStatements=true, maxOpenPreparedStatements=xxx)</li>
<li>Access to the underlying connection is blocked by default
  You can access the underlying connection by setting
  accessToUnderlyingConnectionAllowed=true and by using the following construct:
  Connection dconn = ((DelegatingConnection) conn).getInnermostDelegate();</li>
<li>New minIdle parameter for a minimum number of idle connections ready for use
<li>New connection default properties: defaultCatalog and defaultTransactionIsolation
<li>Missing driverClassName will now give the following error "No suitable driver"
<li>Bad validationQuery will produce a meaningful SQLException
<li>UML Class and sequence diagrams, configuration documentation
<li>The following issues were resolved since v1.0: (see Bugzilla for complete description)
