- `EventOption` and the related `NewEventConfig` function are added to the `go.opentelemetry.io/otel` package to configure Span events. (#1254)
- A `TextMapPropagator` and associated `TextMapCarrier` are added to the `go.opentelemetry.io/otel/oteltest` package to test TextMap type propagators and their use. (#1259)
- `SpanContextFromContext` returns `SpanContext` from context. (#1255)
- Add an opencensus to opentelemetry tracing bridge. (#1305)
