Breaking Changes

We have implemented a workaround for the issue in Node where the asynchronous context is lost when using async/await with a non-native promise. This comes with a slight performance impact. If your services are not using non-native promises at all and you want to avoid the additional cost, the feature can be disabled when initializing the tracer by using tracer.init({ trackAsyncScope: false }).
