Full Changelog: 0.11.0...0.11.1

0.11.0

A year after the release of 0.10.0 of Quinn, our popular community-oriented pure-Rust implementation of QUIC, we have a slew of improvements. The highlights are an upgrade to rustls 0.23 and ring 0.17 (which unfortunately got delayed by incompatibilities introduced in the rustls 0.22), a new API to triage incoming connections and a number of performance improvements. The quinn-udp crate has seen a lot of improvements, including much improved Windows support.

We've recently started an OpenCollective account which we hope commercial organizations relying on Quinn will donate to in order to support ongoing development and maintenance of the project. Since the previous major release, we've also started a Discord channel which has become the preferred (synchronous/ephemeral) communication channel for the project.

This release supports Rust 1.66 and newer.

Thanks to all contributors on behalf of the Quinn team, @Ralith and @djc!
