<h2>🚀 urllib3 is fundraising for HTTP/2 support</h2>
<p><a

is raising ~$40,000 USD</a> to release HTTP/2 support and ensure
long-term sustainable maintenance of the project after a sharp decline

financially</a> to ensure HTTP/2 support is developed sustainably and
maintained for the long-haul.</p>
<p>Thank you for your support.</p>
<h2>Changes</h2>
<ul>

headers to strip from requests when redirecting to a different host. As
before, different headers can be set via

<h2>2.2.0</h2>
<h2>🖥️ urllib3 now works in the browser</h2>
<p>:tada: <strong>This release adds experimental support for <a
href="https://urllib3.readthedocs.io/en/stable/reference/contrib/emscripten.html">using
urllib3 in the browser with Pyodide</a>!</strong> 🎉</p>
<p>Thanks to Joe Marshall (<a
href="https://github.com/joemarshall"><code>@​joemarshall</code></a>)
for contributing this feature. This change was possible thanks to work
done in urllib3 v2.0 to detach our API from <code>http.client</code>.
