<h2>v3.0.0</h2>
<p><code>3.0.0</code> is a major release that moves the action runtime
from Node 20 to Node 24.
Use <code>v3</code> on GitHub-hosted runners and self-hosted fleets that
already support the
Node 24 Actions runtime. If you still need the last Node 20-compatible
line, stay on
<code>v2.6.2</code>.</p>
<h2>What's Changed</h2>
<h3>Other Changes 🔄</h3>
<ul>
<li>Move the action runtime and bundle target to Node 24</li>
<li>Update <code>@types/node</code> to the Node 24 line and allow future
Dependabot updates</li>
<li>Keep the floating major tag on <code>v3</code>; <code>v2</code>
remains pinned to the latest <code>2.x</code> release</li>
</ul>

<h2>v2.6.1</h2>
<p><code>2.6.1</code> is a patch release focused on restoring linked
discussion thread creation when
<code>discussion_category_name</code> is set. It fixes
<code>[#764](https://github.com/softprops/action-gh-release/issues/764)</code>,
where the draft-first publish flow
stopped carrying the discussion category through the final publish
step.</p>
<p>If you still hit an issue after upgrading, please open a report with
the bug template and include a minimal repro or sanitized workflow
snippet where possible.</p>
<h2>What's Changed</h2>
<h3>Bug fixes 🐛</h3>
<ul>
<li>fix: preserve discussion category on publish by <a
href="https://github.com/chenrui333"><code>@​chenrui333</code></a> in <a

</ul>
<h2>v2.6.0</h2>
<p><code>2.6.0</code> is a minor release centered on
<code>previous_tag</code> support for
<code>generate_release_notes</code>,
which lets workflows pin GitHub's comparison base explicitly instead of
relying on the default range.
It also includes the recent concurrent asset upload recovery fix, a
<code>working_directory</code> docs sync,
a checked-bundle freshness guard for maintainers, and clearer
immutable-prerelease guidance where
GitHub platform behavior imposes constraints on how prerelease asset
uploads can be published.</p>
<p>If you still hit an issue after upgrading, please open a report with
the bug template and include a minimal repro or sanitized workflow
snippet where possible.</p>
