+#############################
+Upgrading from 1.4.0 to 1.4.1
+#############################
+
+.. note:: 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.
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace the following directories in your "system" folder with the new
+versions:
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.
+
+-  codeigniter
+-  drivers
+-  helpers
+-  libraries
+
+Step 2: Update your config.php file
+===================================
+
+Open your application/config/config.php file and add this new item::
+
+
+
+    /*
+    |--------------------------------------------------------------------------
+    | 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;
+
+Step 3: Rename an Autoload Item
+===============================
+
+Open the following file: application/config/autoload.php
+
+Find this array item::
+
+	$autoload['core'] = array();
+
+And rename it to this::
+
+	$autoload['libraries'] = array();
+
+This change was made to improve clarity since some users were not sure
+that their own libraries could be auto-loaded.
+
+Step 4: Update your user guide
+==============================
+
+Please also replace your local copy of the user guide with the new
+version.
