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 Session Table

- -

If you are using the Session class in your application, AND if you are storing session data to a database, you must add a new column named user_data to your session table. -Here is an example of what this column might look like for MySQL: - -user_data text NOT NULL - -

To add this column you will run a query similar to this:

- -ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL - -

You'll find more information regarding the new Session functionality in the Session class page.

Step 3: Update your user guide

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