<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/sigstore/cosign-installer/releases">sigstore/cosign-installer's
releases</a>.</em></p>
<blockquote>
<h2>v4.0.0</h2>
<h2>What's Changed?</h2>
<p><strong>Note:</strong> You must upgrade to cosign-installer v4 if you
want to install <a
href="https://blog.sigstore.dev/cosign-3-0-available/">Cosign v3+</a>.
You may still install Cosign v2.x with cosign-installer v4.</p>
<p>In version v3+, using <code>cosign sign-blob</code> requires adding
the <code>--bundle</code> flag which may require you to update your
signing command.</p>
<ul>
<li>Add support for Cosign v3 releases (<a
href="https://redirect.github.com/sigstore/cosign-installer/issues/201">#201</a>)</li>
</ul>
<h2>v3.10.1</h2>
<h2>What's Changed?</h2>
<p><strong>Note:</strong> cosign-installer v3.x cannot be used to
install <a href="https://blog.sigstore.dev/cosign-3-0-available/">Cosign
v3.x</a>. You must upgrade to cosign-installer v4 in order to use Cosign
v3.</p>
<p><strong>Note:</strong> This is planned to be the final release of
Cosign v2, though we will cut new releases for any critical security or
bug fixes. We recommend transitioning to <a
href="https://blog.sigstore.dev/cosign-3-0-available/">Cosign
v3</a>.</p>
<ul>
<li>Bump default Cosign to v2.6.1 (<a
