The GraphOS Schema Proposals feature is a centralized change management workflow that streamlines the process of proposing, reviewing, and approving schema changes to a supergraph. This allows developers and platform engineers across multiple teams to collaborate more effectively on designing and implementing federated GraphQL APIs. The feature includes integrated checks to validate proposed schema changes, automated publishing of approved changes, and safeguards to prevent unapproved changes from being published. With GraphOS Schema Proposals, organizations can improve developer velocity, reduce the risk of breaking client apps, and ensure that changes do not conflict with other backend teams' subgraph schemas.
