 - The `DroppedAttributeCount` field of the `Span` in the `go.opentelemetry.io/otel` package now only represents the number of attributes dropped for the span itself.
   It no longer is a conglomerate of itself, events, and link attributes that have been dropped. (#1771)
 - Make `ExportSpans` in Jaeger Exporter honor context deadline. (#1773)
