<h2>2.4.0</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. 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>
