⚠️ Warning

These modules are almost certainly going to break everything. They do every time they update. If you update even one repo's OTEL modules, go will then pull in new versions due to MVS which will cause your repo to break. All otel pull requests need to be merged basically at the same time, and after all of the modules have been updated to be compatible with each other.

Added

• Add the new go.opentelemetry.io/contrib/instrgen package to provide auto-generated source code instrumentation. (#​3068, #​3108)

• Add "go.opentelemetry.io/contrib/config" package that includes configuration models generated via go-jsonschema. (#​4376)
• Add NewSDK function to "go.opentelemetry.io/contrib/config". The initial implementation only returns noop providers. (#​4414)

• The UnaryServerInterceptor in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc now sets gRPC status code correctly for the rpc.server.duration metric. (#​4481)
• The NewClientHandler, NewServerHandler in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc now honor otelgrpc.WithMessageEvents options. (#​4536)

v1.20.0: /v0.43.0

Compare Source

This release brings a breaking change for custom trace API implementations. Some interfaces (TracerProvider, Tracer, Span) now embed the go.opentelemetry.io/otel/trace/embedded types. Implementors need to update their implementations based on what they want the default behavior to be. See the "API Implementations" section of the trace API package documentation for more about how to accomplish this.

Added

• Add go.opentelemetry.io/otel/bridge/opencensus.InstallTraceBridge, which installs the OpenCensus trace bridge, and replaces opencensus.NewTracer. (#​4567)
• Add scope version to trace and metric bridges in go.opentelemetry.io/otel/bridge/opencensus. (#​4584)
• Add the go.opentelemetry.io/otel/trace/embedded package to be embedded in the exported trace API interfaces. (#​4620)
• Add the go.opentelemetry.io/otel/trace/noop package as a default no-op implementation of the trace API. (#​4620)
• Add context propagation in go.opentelemetry.io/otel/example/dice. (#​4644)
• Add view configuration to go.opentelemetry.io/otel/example/prometheus. (#​4649)
• Add go.opentelemetry.io/otel/metric.WithExplicitBucketBoundaries, which allows defining default explicit bucket boundaries when creating histogram instruments. (#​4603)
• Add Version function in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc. (#​4660)
• Add Version function in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp. (#​4660)
• Add Summary, SummaryDataPoint, and QuantileValue to go.opentelemetry.io/sdk/metric/metricdata. (#​4622)
• go.opentelemetry.io/otel/bridge/opencensus.NewMetricProducer now supports exemplars from OpenCensus. (#​4585)
• Add support for WithExplicitBucketBoundaries in go.opentelemetry.io/otel/sdk/metric. (#​4605)
• Add support for Summary metrics in go.opentelemetry.io/otel/bridge/opencensus. (#​4668)

Deprecated

• Deprecate go.opentelemetry.io/otel/bridge/opencensus.NewTracer in favor of opencensus.InstallTraceBridge. (#​4567)
• Deprecate go.opentelemetry.io/otel/example/fib package is in favor of go.opentelemetry.io/otel/example/dice. (#​4618)
• Deprecate go.opentelemetry.io/otel/trace.NewNoopTracerProvider.
  Use the added NewTracerProvider function in go.opentelemetry.io/otel/trace/noop instead. (#​4620)
• Deprecate go.opentelemetry.io/otel/example/view package in favor of go.opentelemetry.io/otel/example/prometheus. (#​4649)
• Deprecate go.opentelemetry.io/otel/exporters/otlp/otlpmetric. (#​4693)

Changed

• go.opentelemetry.io/otel/bridge/opencensus.NewMetricProducer returns a *MetricProducer struct instead of the metric.Producer interface. (#​4583)
• The TracerProvider in go.opentelemetry.io/otel/trace now embeds the go.opentelemetry.io/otel/trace/embedded.TracerProvider type.
  This extends the TracerProvider interface and is is a breaking change for any existing implementation.
  Implementors need to update their implementations based on what they want the default behavior of the interface to be.
  See the "API Implementations" section of the go.opentelemetry.io/otel/trace package documentation for more information about how to accomplish this. (#​4620)

• Retry for 502 Bad Gateway and 504 Gateway Timeout HTTP statuses in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#​4670)
