<h2>2.2.1</h2>
<h2>🚀 urllib3 is fundraising for HTTP/2 support</h2>
<p><a
href="https://sethmlarson.dev/urllib3-is-fundraising-for-http2-support">urllib3
is raising ~$40,000 USD</a> to release HTTP/2 support and ensure
long-term sustainable maintenance of the project after a sharp decline
in financial support for 2023. If your company or organization uses
Python and would benefit from HTTP/2 support in Requests, pip, cloud
SDKs, and thousands of other projects <a
href="https://opencollective.com/urllib3">please consider contributing
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>
<li>Fixed issue where <code>InsecureRequestWarning</code> was emitted
for HTTPS connections when using Emscripten. (<a
href="https://redirect.github.com/urllib3/urllib3/issues/3331">#3331</a>)</li>
<li>Fixed <code>HTTPConnectionPool.urlopen</code> to stop automatically
casting non-proxy headers to <code>HTTPHeaderDict</code>. This change
was premature as it did not apply to proxy headers and
<code>HTTPHeaderDict</code> does not handle byte header values correctly
yet. (<a
href="https://redirect.github.com/urllib3/urllib3/issues/3343">#3343</a>)</li>
<li>Changed <code>ProtocolError</code> to
<code>InvalidChunkLength</code> when response terminates before the
chunk length is sent. (<a
href="https://redirect.github.com/urllib3/urllib3/issues/2860">#2860</a>)</li>
<li>Changed <code>ProtocolError</code> to be more verbose on incomplete
reads with excess content. (<a
href="https://redirect.github.com/urllib3/urllib3/issues/3261">#3261</a>)</li>
