Schema previews

You can preview upcoming features and changes to the GitHub GraphQL schema before they are added to the GitHub GraphQL API.

About schema previews

During the preview period, we may change some features based on developer feedback. If we do make changes, we'll announce them on the developer blog without advance notice.
