 - Populate the Hermes runtime version on JS profiles instead of sending an empty value ([#6817](https://github.com/getsentry/sentry-react-native/pull/6817))
+- Mark `@sentry/react-native` as side-effect free so bundlers can tree-shake unused exports ([#6829](https://github.com/getsentry/sentry-react-native/pull/6829))
