Upgrading from 1.5.3 to 1.5.4
*****************************

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 these files and directories in your “system” folder with the
new versions:

* application/config/mimes.php

* system/codeigniter

* system/database

* system/helpers

* system/libraries

* system/plugins

Note:

  If you have any custom developed files in these folders please make
  copies of them first.


Step 2: Add charset to your config.php
======================================

Add the following to application/config/config.php

   /*
   |--------------------------------------------------------------------------
   | Default Character Set
   |--------------------------------------------------------------------------
   |
   | This determines which character set is used by default in various methods
   | that require a character set to be provided.
   |
   */
   $config['charset'] = "UTF-8";


Step 3: Autoloading language files
==================================

If you want to autoload any language files, add this line to
application/config/autoload.php

   $autoload['language'] = array();


Step 4: Update your user guide
==============================

Please also replace your local copy of the user guide with the new
version.
