If you use the GitHub GraphQL API for team notification dashboards, audit-log exports, or any kind of organization compliance reporting, you have nine days when this lands. On July 1, 2026, GitHub deletes two fields from the Team type and the fields from seventeen audit-log entry types.
The fields are listed in GitHub's own breaking changes log:
Team.viewerSubscription — removed. Reason: "Team notifications subscriptions are being deprecated."
Team.viewerCanSubscribe — removed. Same reason.
All scalar fields on TeamAddMemberAuditEntry, TeamAddRepositoryAuditEntry, TeamChangeParentTeamAuditEntry, TeamRemoveMemberAuditEntry, TeamRemoveRepositoryAuditEntry, and twelve sibling repository/audit entry types — removed. Reason: "The GraphQL audit-log is deprecated. Please use the REST API instead."
