<b>NOTE: DBCP v1.2 requires Pool v1.2, make sure you use the correct version!
</p>
<p>
There were some new features were added since the 1.1 release on 20 October 2003.
<ul>
<li>Performance optimizations for the PoolableConnectionFactory of BasicDataSource.
<br/>
<li>Add BasicDataSourceFactory.createDataSource(Properties properties) for creating a BasicDataSource.
<br/>
<li>Add initialSize parameter to do pre-loading of the connection.
<br/>
<li>Refactoring of the DelegatingStatement classes.
<br/>
<li>Make some properties dynamic (changeble at runtime), this will be completed in next release.
<br/>
<li>Improvements to the prepared statement pooling.
<br/>
<li>Driver specific changes/optimizations for: Oracle, Informix, DaffodilDB.
<br/>
<li>Several fixes for PerUserPoolDataSource
<br/>
<li>PoolingDriver uses now a PoolGuardConnectionWrapper by default. If access to the
underlying connection is needed, you have to enable it: PoolingDriver.setAccessToUnderlyingConnectionAllowed(true)</li>
<br/>
<li>The following issues were resolved since v1.1: (see Bugzilla for complete description)
