############################# 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
