-#############################
-Upgrading from 1.3.3 to 1.4.0
-#############################
-
-.. note:: The instructions on this page assume you are running version
-	1.3.3. 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.
-
--  application/config/**hooks.php**
--  application/config/**mimes.php**
--  codeigniter
--  drivers
--  helpers
--  init
--  language
--  libraries
--  scaffolding
-
-Step 2: Update your config.php file
-===================================
-
-Open your application/config/config.php file and add these new items::
-
-
-
-    /*
-    |--------------------------------------------------------------------------
-    | Enable/Disable System Hooks
-    |--------------------------------------------------------------------------
-    |
-    | If you would like to use the "hooks" feature you must enable it by
-    | setting this variable to TRUE (boolean).  See the user guide for details.
-    |
-    */
-    $config['enable_hooks'] = FALSE;
-
-
-    /*
-    |--------------------------------------------------------------------------
-    | Allowed URL Characters
-    |--------------------------------------------------------------------------
-    |
-    | This lets you specify which characters are permitted within your URLs.
-    | When someone tries to submit a URL with disallowed characters they will
-    | get a warning message.
-    |
-    | As a security measure you are STRONGLY encouraged to restrict URLs to
-    | as few characters as possible.  By default only these are allowed: a-z 0-9~%.:_-
-    |
-    | Leave blank to allow all characters -- but only if you are insane.
-    |
-    | DO NOT CHANGE THIS UNLESS YOU FULLY UNDERSTAND THE REPERCUSSIONS!!
-    |
-    */
-    $config['permitted_uri_chars'] = 'a-z 0-9~%.:_-';
-
-Step 3: Update your user guide
-==============================
-
-Please also replace your local copy of the user guide with the new
-version.
