 ### Features
 
 - The SDK now automatically propagates the trace-context to the native layer. This allows to connect errors on different layers of the application. ([#4137](https://github.com/getsentry/sentry-java/pull/4137))
+- Capture OpenTelemetry span events ([#3564](https://github.com/getsentry/sentry-java/pull/3564))
+  - OpenTelemetry spans may have exceptions attached to them (`openTelemetrySpan.recordException`). We can now send those to Sentry as errors.
+  - Set `capture-open-telemetry-events=true` in `sentry.properties` to enable it
+  - Set `sentry.capture-open-telemetry-events=true` in Springs `application.properties` to enable it
+  - Set `sentry.captureOpenTelemetryEvents: true` in Springs `application.yml` to enable it
