 ### Features
 
 - Add manifest `AutoInit` to integrations list ([#2795](https://github.com/getsentry/sentry-java/pull/2795))

 ### Fixes
 
 - Set `environment` from `SentryOptions` if none persisted in ANRv2 ([#2809](https://github.com/getsentry/sentry-java/pull/2809))
+- Remove code that set `tracesSampleRate` to `0.0` for Spring Boot if not set ([#2800](https://github.com/getsentry/sentry-java/pull/2800))
