The release of mitmproxy 11 brings full support for HTTP/3 in both transparent and reverse proxy modes, alongside DNS improvements. Developed during the Google Summer of Code program, HTTP/3 now “just works” for reverse proxies and transparent proxy modes, although Chrome’s distrust of user-added Certificate Authorities for QUIC poses a limitation. The improved DNS support includes a switch to Hickory DNS for non-A/AAAA queries and supports DNS-over-TCP and stripping Encrypted Client Hello keys. These advancements are significant for privacy and network traffic. The work was supported by Google Summer of Code and the NGI0 Entrust fund, with special thanks to mentor Maximilian Hils.
