🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD 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 please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Changes

• Fixed issue where InsecureRequestWarning was emitted for HTTPS connections when using Emscripten. (#3331)
• Fixed HTTPConnectionPool.urlopen to stop automatically casting non-proxy headers to HTTPHeaderDict. This change was premature as it did not apply to proxy headers and HTTPHeaderDict does not handle byte header values correctly yet. (#3343)
• Changed ProtocolError to InvalidChunkLength when response terminates before the chunk length is sent. (#2860)
• Changed ProtocolError to be more verbose on incomplete reads with excess content. (#3261)
