Changelog

0.3.1

• Add --tls-client-crt-file and --tls-client-rsa-key-file options to the example mqttc. Thanks to marcelbuesing for the PR!
• Add more explanation of how to configure TLS to the ClientBuilder docs.

0.3.0

• Add WebSocket support under Cargo feature "websocket".
• Switch ClientBuilder to use a URL instead of host and port. This was a breaking change to make it simple for consumers to switch protocol.

Thanks to JarredAllen for the implementation!

0.2.0

• Update tokio dependency to v1.2.0. Thanks to marcelbuesing for the PR!

0.1.7

• Implement Debug for Client and ClientOptions
• Reduce dependencies for faster and less fiddly builds: env_logger and structopt are now dev-dependencies, rustls is now optional but included by default as part of the tls feature.

Thanks to marcelbuesing for the PRs!
