Before on version 2.0 on your landing pages, you would download tracking.php hosted by you. With version 2.1, you will use a tracking.js file that is hosted by us.
What this means is that all your existing landing pages would continue to work, but they would need to be updated if you decide to update your campaign to 2.1.
Even though 2.0 landing pages continue to work, upgrading them to 2.1 will allow your landing pages to take advantage of new and upcoming features.
You can get the integration code in the help section, accessible at the upper right corner "?" icon.
