+Upgrading from 2.1.4 to 2.2.0
+#############################
+
+.. note:: The :doc:`Encrypt Class <libraries/encrypt>` now requires the
+	Mcrypt extension. If you were previously using the Encrypt Class
+	without Mcrypt, then this is a breaking change.  You must install
+	the Mcrypt extension in order to upgrade. For information on
+	installing Mcrypt please see the PHP `documentation
+	<http://php.net/manual/en/mcrypt.setup.php>`.
+
+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.
