This release adds support for HTTP/3 Trailers, for both the server and the client side (#4581, #4630, #4656, #4639). Trailers work exactly the same way as for HTTP/1.1 and HTTP/2.
A big thank you to @sudorandom for contributing this feature!
Fixes
idle timeout calculation when the peer sends a max_idle_timeout of 0 (or omits the transport parameter): #4666
fix handling of corrupted coalesced 1-RTT packets: #4663
qpack: don't reject literal field lines with name references if N bit is set to 1: quic-go/qpack#52
http3: correctly set the http.Response.ContentLength on responses that don't set the Content-Length header: #4645
http3: reject connection-specific header fields (Connection, Keep-Alive, Proxy-Connection, Transfer-Encoding, Upgrade and TE != "trailers"): #4646, #4655
Breaking Changes
quic.VersionNumber and logging.VersionNumber were removed: #4627
Heads-Up
@sukunrt recently discovered and reported a race condition in the new time.Timer stopping logic introduced in Go 1.23. This manifests as a connection deadlock in quic-go. See #4659 and golang/go#69312 for more details. The new behavior is enabled when compiling with Go 1.23.x, and when the Go version in go.mod is set to Go 1.23.x.
Until this issue is fixed, it is recommended to either use Go 1.22.x, or to use GODEBUG="asynctimerchan=1" when compiling quic-go.
