 ### Fixes
 
+- Preserve Hermes internal bytecode frames as non-application frames when rewriting Expo stack traces ([#6848](https://github.com/getsentry/sentry-react-native/pull/6848))
 - Fix stale `turbo_module.*` tags on Android native crashes ([#6823](https://github.com/getsentry/sentry-react-native/pull/6823))
 - Forward image attachments to Spotlight instead of stripping them from the envelope ([#6818](https://github.com/getsentry/sentry-react-native/pull/6818))
 - Don't crash the iOS app when Sentry is initialized with an invalid DSN ([#6825](https://github.com/getsentry/sentry-react-native/pull/6825))
