releases</a>.</em></p>
<blockquote>
<h2>v8.0.0</h2>
<h2>v8 - What's new</h2>
<h3>Direct downloads</h3>
<p>To support direct uploads in <code>actions/upload-artifact</code>,
the action will no longer attempt to unzip all downloaded files.
Instead, the action checks the <code>Content-Type</code> header ahead of
unzipping and skips non-zipped files. Callers wishing to download a
zipped file as-is can also set the new <code>skip-decompress</code>
parameter to <code>false</code>.</p>
<h3>Enforced checks (breaking)</h3>
<p>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 <code>digest-mismatch</code> parameter. To be secure by
default, we are now defaulting the behavior to <code>error</code> which
will fail the workflow run.</p>
<h3>ESM</h3>
<p>To support new versions of the @actions/* packages, we've upgraded
the package to ESM.</p>

<h2>v7.0.0</h2>
<h2>v7 - What's new</h2>
<blockquote>
<p>[!IMPORTANT]
actions/download-artifact@v7 now runs on Node.js 24 (<code>runs.using:
node24</code>) and requires a minimum Actions Runner version of 2.327.1.
If you are using self-hosted runners, ensure they are updated before
upgrading.</p>
</blockquote>
<h3>Node.js 24</h3>
<p>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.</p>
