Upgrading from v1.x

When upgrading to Form Tools 3 by download an upgrade package from the Form Tools website it will include version 2.x of the API. In terms of your own form integration, no further work is necessary: it should all just "work".

Here's what's happening. The old api.php file used in API v1.x contains the function reference (PHP functions of the form ft_api_* which you'll have used in your code). This file has been replaced with simple wrapper methods with the same name as the old methods. These now call the new API.class.php class methods. This is what allows for a seamless upgrade.
