This nouveau release ships with countless features and improvements, specifically for circuit breaking. We've made progress on refactoring and improving circuit breaking feature, including arbitrary statistic duration support, half-open recovery, enhanced slow request ratio strategy, state change observer and more. We've also brought various versatile integrations including Java EE (JAX-RS and CDI), Quarkus and HTTP client (Apache HttpClient and OkHttp), which could cover more developers.
