open-telemetry/opentelemetry-go v0.10.0

Release v0.10.0

on GitHub

This release migrates the default OpenTelemetry SDK into its own Go module, decoupling the SDK from the API and reducing dependencies for instrumentation packages.

Added

• The Zipkin exporter now has NewExportPipeline and InstallNewPipeline constructor functions to match the common pattern.
  These function build a new exporter with default SDK options and register the exporter with the global package respectively. (#944)
• Add propagator option for gRPC instrumentation. (#986)
• The testtrace package now tracks the trace.SpanKind for each span. (#987)

Changed

• Replace the RegisterGlobal Option in the Jaeger exporter with an InstallNewPipeline constructor function.
  This matches the other exporter constructor patterns and will register a new exporter after building it with default configuration. (#944)
• The trace (go.opentelemetry.io/otel/exporters/trace/stdout) and metric (go.opentelemetry.io/otel/exporters/metric/stdout) stdout exporters are now merged into a single exporter at go.opentelemetry.io/otel/exporters/stdout.
  This new exporter was made into its own Go module to follow the pattern of all exporters and decouple it from the go.opentelemetry.io/otel module. (#956, #963)
• Move the go.opentelemetry.io/otel/exporters/test test package to go.opentelemetry.io/otel/sdk/export/metric/metrictest. (#962)
• The go.opentelemetry.io/otel/api/kv/value package was merged into the parent go.opentelemetry.io/otel/api/kv package. (#968)
  • value.Bool was replaced with kv.BoolValue.
  • value.Int64 was replaced with kv.Int64Value.
  • value.Uint64 was replaced with kv.Uint64Value.
  • value.Float64 was replaced with kv.Float64Value.
  • value.Int32 was replaced with kv.Int32Value.
  • value.Uint32 was replaced with kv.Uint32Value.
  • value.Float32 was replaced with kv.Float32Value.
  • value.String was replaced with kv.StringValue.
  • value.Int was replaced with kv.IntValue.
  • value.Uint was replaced with kv.UintValue.
  • value.Array was replaced with kv.ArrayValue.
• Rename Infer to Any in the go.opentelemetry.io/otel/api/kv package. (#972)
• Rename go.opentelemetry.io/otel/sdk/metric/aggregator/test package to go.opentelemetry.io/otel/sdk/metric/aggregator/aggregatortest. (#980)
• Make the SDK into its own Go module called go.opentelemetry.io/otel/sdk. (#985)
• Changed the default trace Sampler from AlwaysOn to ParentOrElse(AlwaysOn). (#989)

Removed

• The IndexedAttribute function from the go.opentelemetry.io/otel/api/label package was removed in favor of IndexedLabel which it was synonymous with. (#970)

Fixed

• Bump github.com/golangci/golangci-lint from 1.28.3 to 1.29.0 in /tools. (#953)
• Bump github.com/google/go-cmp from 0.5.0 to 0.5.1. (#957)
• Use global.Handle for span export errors in the OTLP exporter. (#946)
• Correct Go language formatting in the README documentation. (#961)
• Remove default SDK dependencies from the go.opentelemetry.io/otel/api package. (#977)
• Remove default SDK dependencies from the go.opentelemetry.io/otel/instrumentation package. (#983)
• Move documented examples for go.opentelemetry.io/otel/instrumentation/grpctrace interceptors into Go example tests. (#984)
