Thanks to Joe Marshall (@​joemarshall) for contributing this feature. This change was possible thanks to work done in urllib3 v2.0 to detach our API from http.client. Please report all bugs to the urllib3 issue tracker.
🚀 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
Added support for Emscripten and Pyodide, including streaming support in cross-origin isolated browser environments where threading is enabled. (#2951)
Added support for HTTPResponse.read1() method. (#3186)
Fixed issue where requests against urls with trailing dots were failing due to SSL errors
when using proxy. (#2244)
Fixed HTTPConnection.proxy_is_verified and HTTPSConnection.proxy_is_verified to be always set to a boolean after connecting to a proxy. It could be None in some cases previously. (#3130)
Fixed an issue where headers passed in a request with json= would be mutated (#3203)
Fixed HTTPSConnection.is_verified to be set to False when connecting from a HTTPS proxy to an HTTP target. It was set to True previously. (#3267)
Fixed handling of new error message from OpenSSL 3.2.0 when configuring an HTTP proxy as HTTPS (#3268)
Fixed TLS 1.3 post-handshake auth when the server certificate validation is disabled (#3325)
Note for downstream distributors: To run integration tests, you now need to run the tests a second time with the --integration pytest flag. (#3181)
