  • Fixed jaegerremote sampler not behaving properly with per operation strategy set. (#2137)
  • Stopped injecting propagation context into response headers in otelhttp. (#2180)

  • DynamoDB spans created with the go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws package now have the appropriate database attributes added for the operation being performed. These attributes are detected automatically, but it is also now possible to provide a custom function to set attributes using WithAttributeSetter. (#1582)
  • Add resource detector for GCP cloud function. (#1584)
  • Add OpenTracing baggage extraction to the OpenTracing propagator in go.opentelemetry.io/contrib/propagators/ot. (#1880)

Fixed

  • Fixed the region reported by the "go.opentelemetry.io/contrib/detectors/gcp".CloudRun detector to comply with the OpenTelemetry specification. It no longer includes the project scoped region path, instead just the region. (#1546)
  • The "go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp".Transport type now correctly handles protocol switching responses. The returned response body implements the io.ReadWriteCloser interface if the underlying one does. This ensures that protocol switching requests receive a response body that they can write to.
