*If you are a `@sentry/apm` and did manual instrumentation using `hub.startSpan` please be aware of the changes we did

to the API. The recommended entry point for manual instrumentation now is `Sentry.startTransaction` and creating

child Span by calling `startChild` on it. We have internal workarounds in place so the old code should still work

but will be removed in the future. If you are only using the `Tracing` integration there is no need for action.*
