### [`v0.39.0`](https://togithub.com/quic-go/quic-go/releases/tag/v0.39.0)
[Compare Source](https://togithub.com/quic-go/quic-go/compare/v0.38.1...v0.39.0)
#### New Features
- quic-go now uses feeds ECN signals into its congestion controller ([#4059](https://togithub.com/quic-go/quic-go/issues/4059)). ECN is used by routers to signal congestion before queues overflow (and packets are dropped). When using ECN, there are a number of failure modes, which necessitates some rather complex validation logic, see [section 13.4 of RFC 9000](https://datatracker.ietf.org/doc/html/rfc9000#section-13.4) for details. ECN support can be disabled by setting the `QUIC_GO_DISABLE_ECN` environment variable to `true`.
- The HTTP/3 package introduced a `http3.Error`, making the errors returned by the http3 package more useful, and allowing easy assertions of the [HTTP/3 error codes](https://datatracker.ietf.org/doc/html/rfc9114#section-8.1) defined in RFC 9114: [#4039](https://togithub.com/quic-go/quic-go/issues/4039)
#### Other Changes
- The key used to encrypt resumption tokens can now be configured using using `Transport.TokenGeneratorKey`: [#4066](https://togithub.com/quic-go/quic-go/issues/4066)
- The RTT is now saved in session tickets, even when not using 0-RTT, allowing for faster session resumption: [#4042](https://togithub.com/quic-go/quic-go/issues/4042)
- The reason for dial cancelations is now returned, when the context is canceled using a `context.CancelCauseFunc`: [#4078](https://togithub.com/quic-go/quic-go/issues/4078)
When using Go 1.21, make sure to build with (at least) Go 1.21.1, as this release fixes a remote-triggered panic in crypto/tls. See [the release announcement](https://groups.google.com/g/golang-announce/c/Fm51GRLNRvM) for details.
#### Breaking Changes
- `Config.DisableVersionNegotiationPackets` was moved to the `Transport`: [#4047](https://togithub.com/quic-go/quic-go/issues/4047)
- `Config.MaxTokenAge` was moved to the `Transport`: [#4084](https://togithub.com/quic-go/quic-go/issues/4084)
- `Config.MaxRetryTokenAge` was removed. The age limit for Retry tokens is now set to twice the handshake timeout: [#4064](https://togithub.com/quic-go/quic-go/issues/4064)
- The handshake timeout is now set to twice the handshake idle timeout: [#4063](https://togithub.com/quic-go/quic-go/issues/4063). For clients, it is recommend to limit the duration of the handshake by using setting the context on the `Dial` call.
- The `logging.Tracer` and `logging.ConnectionTracer` are now structs (not interfaces): [#4082](https://togithub.com/quic-go/quic-go/issues/4082)
