This version of GitHub Enterprise was discontinued on 2023-01-18. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise. For help with the upgrade, contact GitHub Enterprise support.

API previews

You can use API previews to try out new features and provide feedback before these features become official.

API previews let you try out new endpoints and changes to existing endpoints before they become part of the official GitHub API.

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.

To access an API preview, you'll need to provide a custom media type in the Accept header for your requests. Feature documentation for each preview specifies which custom media type to provide.

Content attachments

You can now provide more information in GitHub for URLs that link to registered domains by using the API to manage Content Attachments. For more information, see "Using content attachments."
