 ==== Breaking Changes
 - Aggregated metrics now consider global labels to be part of a service's identity, and high cardinality global labels may cause services to be obscured {pull}11386[11386]
 - Event protobuf encoding for tail-based sampling changed (to a more efficient encoding) for event timestamp and duration {pull}11386[11386]
+- Use object notation for data_stream fields {pull}11311[11311]
