v8 - What's new

Direct downloads

To support direct uploads in actions/upload-artifact, the action will no longer attempt to unzip all downloaded files. Instead, the action checks the Content-Type header ahead of unzipping and skips non-zipped files. Callers wishing to download a zipped file as-is can also set the new skip-decompress parameter to false.

Enforced checks (breaking)

A previous release introduced digest checks on the download. If a download hash didn't match the expected hash from the server, the action would log a warning. Callers can now configure the behavior on mismatch with the digest-mismatch parameter. To be secure by default, we are now defaulting the behavior to error which will fail the workflow run.

ESM

To support new versions of the @​actions/* packages, we've upgraded the package to ESM.

What's Changed

• Don't attempt to un-zip non-zipped downloads by @​danwkennedy in #​460
• Add a setting to specify what to do on hash mismatch and default it to error by @​danwkennedy in #​461

v7.0.0

v7 - What's new

[!IMPORTANT]
actions/download-artifact@​v7 now runs on Node.js 24 (runs.using: node24) and requires a minimum Actions Runner version of 2.327.1. If you are using self-hosted runners, ensure they are updated before upgrading.

Node.js 24

This release updates the runtime to Node.js 24. v6 had preliminary support for Node 24, however this action was by default still running on Node.js 20. Now this action by default will run on Node.js 24.

What's Changed

• Update GHES guidance to include reference to Node 20 version by @​patrikpolyak in #​440
• Download Artifact Node24 support by @​salmanmkc in #​415
• fix: update @​actions/artifact to fix Node.js 24 punycode deprecation by @​salmanmkc in #​451
• prepare release v7.0.0 for Node.js 24 support by @​salmanmkc in #​452

New Contributors

• @​patrikpolyak made their first contribution in #​440

What's Changed

• Update README.md by @​nebuk89 in #​407
• BREAKING fix: inconsistent path behavior for single artifact downloads by ID by @​GrantBirki in #​416

v5.0.0

🚨 Breaking Change

This release fixes an inconsistency in path behavior for single artifact downloads by ID. If you're downloading single artifacts by ID, the output path may change.

What Changed

Previously, single artifact downloads behaved differently depending on how you specified the artifact:

• By name: name: my-artifact → extracted to path/ (direct)
• By ID: artifact-ids: 12345 → extracted to path/my-artifact/ (nested)

Now both methods are consistent:

• By name: name: my-artifact → extracted to path/ (unchanged)
• By ID: artifact-ids: 12345 → extracted to path/ (fixed - now direct)

Migration Guide

✅ No Action Needed If:

• You download artifacts by name
• You download multiple artifacts by ID
• You already use merge-multiple: true as a workaround

⚠️ Action Required If:

You download single artifacts by ID and your workflows expect the nested directory structure.

Before v5 (nested structure):

- uses: actions/download-artifact@v4
  with:
    artifact-ids: 12345
    path: dist

### Files were in: dist/my-artifact/

Where my-artifact is the name of the artifact you previously uploaded

To maintain old behavior (if needed):

- uses: actions/download-artifact@v5
  with:
    artifact-ids: 12345
    path: dist/my-artifact  # Explicitly specify the nested path
