<h1>Upgrading from 1.4.0 to 1.4.1</h1>

<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.4.0.  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>libraries</li>
</ul>


<h2>Step 2: Update your config.php file</h2>

<p>Open your <dfn>application/config/config.php</dfn> file and add this new item:</p>

<pre>

/*
|--------------------------------------------------------------------------
| Output Compression
|--------------------------------------------------------------------------
|
| Enables Gzip output compression for faster page loads.  When enabled,
| the output class will test whether your server supports Gzip.
| Even if it does, however, not all browsers support compression
| so enable only if you are reasonably sure your visitors can handle it.
|
| VERY IMPORTANT:  If you are getting a blank page when compression is enabled it
| means you are prematurely outputting something to your browser. It could
| even be a line of whitespace at the end of one of your scripts.  For
| compression to work, nothing can be sent before the output buffer is called
| by the output class.  Do not "echo" any values with compression enabled.
|
*/
$config['compress_output'] = FALSE;

</pre>


<h2>Step 3: Rename an Autoload Item</h2>

<p>Open the following file: <dfn>application/config/autoload.php</dfn></p>

<p>Find this array item:</p>

<code>$autoload['core'] = array();</code>

<p>And rename it to this:</p>

<code>$autoload['libraries'] = array();</code>

<p>This change was made to improve clarity since some users were not sure that their own libraries could be auto-loaded.</p>


<h2>Step 4: Update your user guide</h2>

<p>Please also replace your local copy of the user guide with the new version.</p>
