+
+<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 Code Igniter 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>
