GitHub Copilot Enterprise Adds In-Product Validator for Managed Settings
GitHub Copilot Enterprise now includes an in-product validator for its managed settings, designed to help administrators ensure proper policy enforcement. This tool automatically detects issues like malformed JSON, unsupported configurations, and invalid team mappings that could prevent policies from taking effect. Errors are displayed in the "Copilot settings validation" section of the enterprise AI controls page, providing specific file and JSON path details for efficient correction. The validator supports configuration files such as `copilot/managed-settings.json` and `copilot/team-mappings.json`, along with any referenced team settings.

GitHub Actions API and UI Workflow Run Queries Now Show Capped Counts
GitHub Actions API and UI queries for workflow runs now display "2,500+" instead of an exact number when results exceed 2,500 records. This change is implemented to prevent timeouts and improve the accuracy of reported counts, as larger queries frequently returned incomplete numbers. Integrations or scripts relying on precise counts for over 2,500 records should narrow their filters, such as by adding a date range. The update is currently rolling out on github.com and GitHub Enterprise Cloud.

GitHub Actions Removes Expired Artifacts From UI and API
GitHub Actions has updated its handling of expired artifacts, which are now completely removed from the UI's run summary and the REST API. This change addresses user confusion caused by previously visible "Expired" labels for artifacts whose underlying files had already been deleted from storage. While expired artifacts are no longer displayed, information about a workflow run's produced artifacts remains accessible within the run's logs. This update clarifies the artifact lifecycle without affecting retention settings or billing.

GitHub Enterprise Cloud introduces proof of presence for high-impact actions
GitHub Enterprise Cloud now supports requiring interactive re-authentication or multi-factor challenges for high-impact actions, expanding sudo mode for enhanced enterprise security. This public preview feature helps prevent supply chain attacks stemming from stolen session cookies or tokens by verifying a real, authorized person is acting. It is currently scoped to managed user (EMU) enterprises on github.com and GHEC-DR that use Microsoft Entra ID as their SSO identity provider. The feature also assists regulated customers in meeting compliance requirements for fresh authentication.

GitHub Actions Deprecates Node 20, Requires Node 24 for JavaScript Actions
GitHub Actions runners have removed Node 20 support, now exclusively using Node 24 for JavaScript actions and discontinuing the `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION` opt-out. This necessitates that maintainers of JavaScript actions update their `runs.using` value to `node24` and publish new releases. Workflow users must also update to the latest action versions that support Node 24. The change also means self-hosted runners on macOS 13.4 and earlier, or ARM32 architectures, are no longer supported due to Node 24's incompatibility.
