Upgrading from 2.1.0 to 2.1.1
*****************************

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 all files and directories in your “system” folder.

Note:

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


Step 2: Replace config/mimes.php
================================

This config file has been updated to contain more user mime-types,
please copy it to _application/config/mimes.php*.


Step 3: Update your IP address tables
=====================================

This upgrade adds support for IPv6 IP addresses. In order to store
them, you need to enlarge your ip_address columns to 45 characters.
For example, CodeIgniter’s session table will need to change

   ALTER TABLE ci_sessions CHANGE ip_address ip_address varchar(45) default '0' NOT NULL
