Upgrading from 1.6.0 to 1.6.1
*****************************

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/language

* system/libraries

Note:

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


Step 2: Update your user guide
==============================

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