Added

  • OTLP Metric exporter supports Histogram aggregation. (#1209)
  • The Code struct from the go.opentelemetry.io/otel/codes package now supports JSON marshaling and unmarshaling as well as implements the Stringer interface. (#1214)
  • A Baggage API to implement the OpenTelemetry specification. (#1217)

Changed

  • Set default propagator to no-op propagator. (#1184)
  • The HTTPSupplier, HTTPExtractor, HTTPInjector, and HTTPPropagator from the go.opentelemetry.io/otel/api/propagation package were replaced with unified TextMapCarrier and TextMapPropagator in the go.opentelemetry.io/otel package. (#1212)
  • The New function from the go.opentelemetry.io/otel/api/propagation package was replaced with NewCompositeTextMapPropagator in the go.opentelemetry.io/otel package. (#1212)
  • The status codes of the go.opentelemetry.io/otel/codes package have been updated to match the latest OpenTelemetry specification.
    They now are Unset, Error, and Ok.
    They no longer track the gRPC codes. (#1214)
  • The StatusCode field of the SpanData struct in the go.opentelemetry.io/otel/sdk/export/trace package now uses the codes package from this package instead of the gRPC project. (#1214)
  • Move the go.opentelemetry.io/otel/api/baggage package into go.opentelemetry.io/otel/propagators. (#1217)

Fixed

  • Copies of data from arrays and slices passed to go.opentelemetry.io/otel/label.ArrayValue() are now used in the returned Value instead of using the mutable data itself. (#1226)

Removed

  • The ExtractHTTP and InjectHTTP functions from the go.opentelemetry.io/otel/api/propagation package were removed. (#1212)
  • The Propagators interface from the go.opentelemetry.io/otel/api/propagation package was removed to conform to the OpenTelemetry specification.
    The explicit TextMapPropagator type can be used in its place as this is the Propagator type the specification defines. (#1212)
  • The SetAttribute method of the Span from the go.opentelemetry.io/otel/api/trace package was removed given its redundancy with the SetAttributes method. (#1216)
  • The internal implementation of Baggage storage is removed in favor of using the new Baggage API functionality. (#1217)
  • Remove duplicate hostname key HostHostNameKey in Resource semantic conventions. (#1219)
  • Nested array/slice support has been removed. (#1226)
