Intuitive Instance Deployment
Significant improvements have been made to credentials, integration configuration and instance deployment.
Integration builders now have the ability to create an easy-to-use configuration page for customer-facing teams. Builders can define config variable names, give hints as to what sort of data is expected, add headers, etc., giving their customer-facing teams an intuitive experience when it comes to deploying an integration.

This ultimately makes for easier and faster deployment of integrations, without the need for developer intervention. Read more about setting up config variables on our integrations article, and about the new instance configuration experience on the instances article.
