Enterprise Teams can now assign the developer and billing roles to users:
Developer Role: Allows Team owners to grant elevated permissions to users on a project-by-project basis. Developers can create deployments but are prevented from performing sensitive actions such as viewing production environment variables or promoting deployments to production.
Billing Role: Allows users to view invoices and edit billing settings while also providing read-only access to all Projects on a Team.
The developer and billing roles are now in public beta. Learn more about roles and permissions of Team members.
