- Add a config option (`Config.DisableVersionNegotiationPackets`) to disable sending of Version Negotiation packets
- Drop support for QUIC draft versions 32 and 34
- Remove the `RetireBugBackwardsCompatibilityMode`, which was intended to mitigate a bug when retiring connection IDs in quic-go in v0.17.2 and ealier
## v0.21.2 (2021-07-15)
- Update qtls (for Go 1.15, 1.16 and 1.17rc1) to include the fix for the crypto/tls panic (see https://groups.google.com/g/golang-dev/c/5LJ2V7rd-Ag/m/YGLHVBZ6AAAJ for details)
## v0.21.0 (2021-06-01)
- quic-go now supports RFC 9000!
## v0.20.0 (2021-03-19)

- Add a `TokenStore` to store address validation tokens.
- Issue and use new connection IDs during a connection.
## v0.12.0 (2019-08-05)
- Implement HTTP/3.
- Rename `quic.Cookie` to `quic.Token` and `quic.Config.AcceptCookie` to `quic.Config.AcceptToken`.

- Enforce application protocol negotiation (via `tls.Config.NextProtos`).
- Use a varint for error codes.
- Add support for [quic-trace](https://github.com/google/quic-trace).
- Add a context to `Listener.Accept`, `Session.Accept{Uni}Stream` and `Session.Open{Uni}StreamSync`.
- Implement TLS key updates.

- Split Session.Close into one method for regular closing and one for closing with an error.
## v0.8.0 (2018-06-26)
- Add support for unidirectional streams (for IETF QUIC).
- Add a `quic.Config` option for the maximum number of incoming streams.
- Add support for QUIC 42 and 43.
- Add dial functions that use a context.
- Multiplex clients on a net.PacketConn, when using Dial(conn).
## v0.7.0 (2018-02-03)
- The lower boundary for packets included in ACKs is now derived, and the value sent in STOP_WAITING frames is ignored.
- Remove `DialNonFWSecure` and `DialAddrNonFWSecure`.
- Expose the `ConnectionState` in the `Session` (experimental API).
- Implement packet pacing.
## v0.6.0 (2017-12-12)
- Add support for QUIC 39, drop support for QUIC 35 - 37

- Add a `quic.Config` option to configure the idle timeout
- Add a `quic.Config` option to configure keep-alive
- Rename the STK to Cookie
- Implement `net.Conn`-style deadlines for streams
- Remove the `tls.Config` from the `quic.Config`. The `tls.Config` must now be passed to the `Dial` and `Listen` functions as a separate parameter. See the [Godoc](https://godoc.org/github.com/lucas-clemente/quic-go) for details.
- Changed the log level environment variable to only accept strings ("DEBUG", "INFO", "ERROR"), see [the wiki](https://github.com/lucas-clemente/quic-go/wiki/Logging) for more details.
