Upgrading from 1.5.4 to 1.6.0
*****************************

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:

* system/codeigniter

* system/database

* system/helpers

* system/libraries

* system/plugins

* system/language

Note:

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


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

Add the following to application/config/config.php with the other
session configuration options

   $config['sess_time_to_update']         = 300;


Step 3: Add $autoload[‘model’]
==============================

Add the following to application/config/autoload.php

   /*
   | -------------------------------------------------------------------
   | Auto-load Model files
   | -------------------------------------------------------------------
   | Prototype:
   |
   | $autoload['model'] = array('my_model');
   |
   */

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


Step 4: Add to your database.php
================================

Make the following changes to your application/config/database.php
file:

Add the following variable above the database configuration options,
with $active_group

   $active_record = TRUE;

Remove the following from your database configuration options

   $db['default']['active_r'] = TRUE;

Add the following to your database configuration options

   $db['default']['char_set'] = "utf8";
   $db['default']['dbcollat'] = "utf8_general_ci";


Step 5: Update your user guide
==============================

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