noq, noq, who's there?

n0 team announces noq, a hard fork of Quinn and their own general-purpose QUIC implementation in Rust. Key features include full QUIC Multipath spec support (making relay and direct UDP paths first-class QUIC concepts), production-grade NAT traversal hole-punching at the QUIC level, QUIC Address Discovery (replacing STUN), extended QLog debugging support, and a WeakConnectionHandle API. noq has been powering iroh since v0.96 and has been tested against picoquic for interoperability. The fork was motivated by the need for deep structural changes around multipath and NAT traversal that would have been an unreasonable burden on Quinn maintainers.
