+
+4. **Enhanced Call Monitoring and Reporting**: We've improved call monitoring with conversation turn tracking, millisecond-precision timestamps, and provided more detailed call end reasons. These enhancements make it easier to track conversation flow, perform precise time calculations, and diagnose specific call termination issues like server overloads or database errors.
+
+5. **Enable Background Denoising**: You can now filter out background noise during calls by setting `Assistant.backgroundDenoisingEnabled` to `true`.
