Our current documents cover different aspects of the ‘core’ QUIC protocol, define a mapping of HTTP semantics to it, and cover selected other topics.
We have a number of experimental implementations in progress. The current goal for interop testing is the 19th Implementation Target.
Implementers should join the quicdev Slack to coordinate testing; contact the WG chairs for an invitation. Note that discussions on Slack are considered IETF contributions under “Note Well”.
