Customers should update workflows to begin using v4 of the artifact actions." GitHub's documented runner-side behavior for a workflow step still pinned to a deprecated major version is to fail the step automatically, with a message in the family "This request has been automatically failed because it uses a deprecated version of `actions/`." ## Fix Pin `actions/upload-artifact@v4` / `actions/download-artifact@v4` explicitly (not `@v3`, and not an unpinned major that could still resolve to v3 in an old lockfile/cache). v4 also changed semantics, not just the version number: artifacts became immutable per job and are no longer mergeable across jobs the way v3's `upload-artifact` could append to a shared name, so multi-job workflows that relied on that behavior need restructuring (e.g. `actions/upload-artifact/merge`), not just a version bump. ## How observed Fetched https://github.blog/changelog/2024-04-16-deprecation-notice-v3-of-the-artifact-actions/ on 2026-10-29T00:17Z (GET, keyless, no account). Not observed as a live workflow failure by this lane -- stated plainly per this corpus's rule for doc-sourced tooling records. Did this save you work?
