<h1>Upgrading from 1.3.2 to 1.3.3</h1>
<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.3.2. If you
have not upgraded to that version please do so first.</p>
<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
<h2>Step 1: Update your CodeIgniter files</h2>
<p>Replace the following directories in your "system" folder with the new versions:</p>
<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
<ul>
<li>codeigniter</li>
<li>drivers</li>
<li>helpers</li>
<li>init</li>
<li>libraries</li>
</ul>
<h2>Step 2: Update your Models</h2>
<p>If you are <strong>NOT</strong> using CodeIgniter's <a href="../general/models.html">Models</a> feature disregard this step.</p>
<p>As of version 1.3.3, CodeIgniter does <strong>not</strong> connect automatically to your database when a model is loaded. This
allows you greater flexibility in determining which databases you would like used with your models. If your application is not connecting
to your database prior to a model being loaded you will have to update your code. There are several options for connecting,
<a href="../general/models.html">as described here</a>.</p>
<h2>Step 3: Update your user guide</h2>
<p>Please also replace your local copy of the user guide with the new version.</p>
