+#############################
+Upgrading from 2.0.2 to 2.0.3
+#############################
+
+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 and replace
+your index.php file. If any modifications were made to your index.php
+they will need to be made fresh in this new one.
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.
+
+Step 2: Update your main index.php file
+=======================================
+
+If you are running a stock index.php file simply replace your version
+with the new one.
+
+If your index.php file has internal modifications, please add your
+modifications to the new file and use it.
+
+Step 3: Replace config/user_agents.php
+=======================================
+
+This config file has been updated to contain more user agent types,
+please copy it to application/config/user_agents.php.
+
+Step 4: Change references of the EXT constant to ".php"
+=======================================================
+
+.. note:: The EXT Constant has been marked as deprecated, but has not
+	been removed from the application. You are encouraged to make the
+	changes sooner rather than later.
+
+Step 5: Remove APPPATH.'third_party' from autoload.php
+=======================================================
+
+Open application/config/autoload.php, and look for the following::
+
+	$autoload['packages'] = array(APPPATH.'third_party');
+
+If you have not chosen to load any additional packages, that line can be
+changed to::
+
+	$autoload['packages'] = array();
+
+Which should provide for nominal performance gains if not autoloading
+packages.
+
+Update Sessions Database Tables
+===============================
+
+If you are using database sessions with the CI Session Library, please
+update your ci_sessions database table as follows::
+
+	     CREATE INDEX last_activity_idx ON ci_sessions(last_activity);     ALTER TABLE ci_sessions MODIFY user_agent VARCHAR(120);
+
