[1.20.0/0.43.0] 2023-11-10

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 information 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.
