[Unreleased]

Changed

[0.13.0] - 2020-10-08

Added

• OTLP Metric exporter supports Histogram aggregation. (open-telemetry#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. (open-telemetry#1214)
• A Baggage API to implement the OpenTelemetry specification. (open-telemetry#1217)
• Add Shutdown method to sdk/trace/provider, shutdown processors in the order they were registered. (open-telemetry#1227)

Changed

• Set default propagator to no-op propagator. (open-telemetry#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/propagation package. (open-telemetry#1212) (open-telemetry#1325)
• The New function from the go.opentelemetry.io/otel/api/propagation package was replaced with NewCompositeTextMapPropagator in the go.opentelemetry.io/otel package. (open-telemetry#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. (open-telemetry#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. (open-telemetry#1214)

Removed

• 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. (open-telemetry#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. (open-telemetry#1216)

[0.12.0] - 2020-09-24

Added

• A SpanConfigure function in go.opentelemetry.io/otel/api/trace to create a new SpanConfig from SpanOptions. (open-telemetry#1108)
• In the go.opentelemetry.io/otel/api/trace package, NewTracerConfig was added to construct new TracerConfigs.
  This addition was made to conform with our project option conventions. (open-telemetry#1155)
• Instrumentation library information was added to the Zipkin exporter. (open-telemetry#1119)
• The SpanProcessor interface now has a ForceFlush() method. (open-telemetry#1166)
• More semantic conventions for k8s as resource attributes. (open-telemetry#1167)

Changed

• Add reconnecting udp connection type to Jaeger exporter.
  This change adds a new optional implementation of the udp conn interface used to detect changes to an agent's host dns record.
  It then adopts the new destination address to ensure the exporter doesn't get stuck. This change was ported from jaegertracing/jaeger-client-go#520. (open-telemetry#1063)
• Replace StartOption and EndOption in go.opentelemetry.io/otel/api/trace with SpanOption.
  This change is matched by replacing the StartConfig and EndConfig with a unified SpanConfig. (open-telemetry#1108)
• Replace the LinkedTo span option in go.opentelemetry.io/otel/api/trace with WithLinks.
  This is be more consistent with our other option patterns, i.e. passing the item to be configured directly instead of its component parts, and provides a cleaner function signature. (open-telemetry#1108)
• The go.opentelemetry.io/otel/api/trace TracerOption was changed to an interface to conform to project option conventions. (open-telemetry#1109)
• Move the B3 and TraceContext from within t...
