Release v0.19.0

Added

  • Added Marshaler config option to otlphttp to enable otlp over json or protobufs. (#1586)
  • A ForceFlush method to the "go.opentelemetry.io/otel/sdk/trace".TracerProvider to flush all registered SpanProcessors. (#1608)
  • Added WithSampler and WithSpanLimits to tracer provider. (#1633, #1702)
  • "go.opentelemetry.io/otel/trace".SpanContext now has a remote property, and IsRemote() predicate, that is true when the SpanContext has been extracted from remote context data. (#1701)
  • A Valid method to the "go.opentelemetry.io/otel/attribute".KeyValue type. (#1703)

Changed

  • trace.SpanContext is now immutable and has no exported fields. (#1573)
    • trace.NewSpanContext() can be used in conjunction with the trace.SpanContextConfig struct to initialize a new SpanContext where all values are known.
  • Update the ForceFlush method signature to the "go.opentelemetry.io/otel/sdk/trace".SpanProcessor to accept a context.Context and return an error. (#1608)
  • Update the Shutdown method to the "go.opentelemetry.io/otel/sdk/trace".TracerProvider return an error on shutdown failure. (#1608)
  • The SimpleSpanProcessor will now shut down the enclosed SpanExporter and gracefully ignore subsequent calls to OnEnd after Shutdown is called. (#1612)
  • "go.opentelemetry.io/sdk/metric/controller.basic".WithPusher is replaced with WithExporter to provide consistent naming across project. (#1656)
  • Added non-empty string check for trace Attribute keys. (#1659)
  • Add description to SpanStatus only when StatusCode is set to error. (#1662)
  • Jaeger exporter falls back to resource.Default's service.name if the exported Span does not have one. (#1673)
  • Jaeger exporter populates Jaeger's Span Process from Resource. (#1673)
  • Renamed the LabelSet method of "go.opentelemetry.io/otel/sdk/resource".Resource to Set. (#1692)
  • Changed WithSDK to WithSDKOptions to accept variadic arguments of TracerProviderOption type in go.opentelemetry.io/otel/exporters/trace/jaeger package. (#1693)
  • Changed WithSDK to WithSDKOptions to accept variadic arguments of TracerProviderOption type in go.opentelemetry.io/otel/exporters/trace/zipkin package. (#1693)
  • "go.opentelemetry.io/otel/sdk/resource".NewWithAttributes will now drop any invalid attributes passed. (#1703)
  • "go.opentelemetry.io/otel/sdk/resource".StringDetector will now error if the produced attribute is invalid. (#1703)

Removed

  • Removed serviceName parameter from Zipkin exporter and uses resource instead. (#1549)
  • Removed WithConfig from tracer provider to avoid overriding configuration. (#1633)
  • Removed the exported SimpleSpanProcessor and BatchSpanProcessor structs.
    These are now returned as a SpanProcessor interface from their respective constructors. (#1638)
  • Removed WithRecord() from trace.SpanOption when creating a span. (#1660)
  • Removed setting status to Error while recording an error as a span event in RecordError. (#1663)
  • Removed jaeger.WithProcess configuration option. (#1673)
  • Removed ApplyConfig method from "go.opentelemetry.io/otel/sdk/trace".TracerProvider and the now unneeded Config struct. (#1693)

Fixed

  • Jaeger Exporter: Ensure mapping between OTEL and Jaeger span data complies with the specification. (#1626)
  • SamplingResult.TraceState is correctly propagated to a newly created span's SpanContext. (#1655)
  • The otel-collector example now correctly flushes metric events prior to shutting down the exporter. (#1678)
  • Do not set span status message in SpanStatusFromHTTPStatusCode if it can be inferred from http.status_code. (#1681)
  • Synchronization issues in global trace delegate implementation. (#1686)
  • Reduced excess memory usage by global TracerProvider. (#1687)

Release v0.16.0

Added

  • Add the ReadOnlySpan and ReadWriteSpan interfaces to provide better control for accessing span data. (#1360)
  • NewGRPCDriver function returns a ProtocolDriver that maintains a single gRPC connection to the collector. (#1369)
  • Added documentation about the project's versioning policy. (#1388)
  • Added NewSplitDriver for OTLP exporter that allows sending traces and metrics to different endpoints. (#1418)
  • Added codeql worfklow to GitHub Actions (#1428)
  • Added Gosec workflow to GitHub Actions (#1429)
  • Add new HTTP driver for OTLP exporter in exporters/otlp/otlphttp. Currently it only supports the binary protobuf payloads. (#1420)

Changed

  • Rename internal/testing to internal/internaltest. (#1449)
  • Rename export.SpanData to export.SpanSnapshot and use it only for exporting spans. (#1360)
  • Store the parent's full SpanContext rather than just its span ID in the span struct. (#1360)
  • Improve span duration accuracy. (#1360)
  • Migrated CI/CD from CircleCI to GitHub Actions (#1382)
  • Remove duplicate checkout from GitHub Actions workflow (#1407)
  • Metric array aggregator renamed exact to match its aggregation.Kind (#1412)
  • Metric exact aggregator includes per-point timestamps (#1412)
  • Metric stdout exporter uses MinMaxSumCount aggregator for ValueRecorder instruments (#1412)
  • NewExporter from exporters/otlp now takes a ProtocolDriver as a parameter. (#1369)
  • Many OTLP Exporter options became gRPC ProtocolDriver options. (#1369)
  • Unify endpoint API that related to OTel exporter. (#1401)
  • Optimize metric histogram aggregator to re-use its slice of buckets. (#1435)
  • Metric aggregator Count() and histogram Bucket.Counts are consistently uint64. (1430)
  • SamplingResult now passed a Tracestate from the parent SpanContext (#1432)
  • Moved gRPC driver for OTLP exporter to exporters/otlp/otlpgrpc. (#1420)
  • The TraceContext propagator now correctly propagates TraceState through the SpanContext. (#1447)
  • Metric Push and Pull Controller components are combined into a single "basic" Controller:
    • WithExporter() and Start() to configure Push behavior
    • Start() is optional; use Collect() and ForEach() for Pull behavior
    • Start() and Stop() accept Context. (#1378)

Removed

  • Remove errUninitializedSpan as its only usage is now obsolete. (#1360)
  • Remove Metric export functionality related to quantiles and summary data points: this is not specified (#1412)
  • Remove DDSketch metric aggregator; our intention is to re-introduce this as an option of the histogram aggregator after new OTLP histogram data types are released (#1412)

Fixed

  • BatchSpanProcessor.Shutdown() will now shutdown underlying export.SpanExporter. (#1443)

    • supports configurable aggregation temporality (default: Cumulative, optional: Stateless). (#1296)
  • The Sampler is now called on local child spans. (#1233)
  • The Kind type from the go.opentelemetry.io/otel/api/metric package was renamed to InstrumentKind to more specifically describe what it is and avoid semantic ambiguity. (#1240)
  • The MetricKind method of the Descriptor type in the go.opentelemetry.io/otel/api/metric package was renamed to Descriptor.InstrumentKind.
    This matches the returned type and fixes misuse of the term metric. (#1240)

    It is replaced by using the AddEvent method with a WithTimestamp option. (#1254)
  • The MockSpan and MockTracer types are removed from go.opentelemetry.io/otel/oteltest.
    Tracer and Span from the same module should be used in their place instead. (#1306)
  • WorkerCount option is removed from go.opentelemetry.io/otel/exporters/otlp. (#1350)

Fixed

  • Rename MergeItererator to MergeIterator in the go.opentelemetry.io/otel/label package. (#1244)
  • The go.opentelemetry.io/otel/api/global packages global TextMapPropagator now delegates functionality to a globally set delegate for all previously returned propagators. (#1258)

Release v0.13.0

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)

Release v0.12.0

Added

  • A SpanConfigure function in go.opentelemetry.io/otel/api/trace to create a new SpanConfig from SpanOptions. (#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. (#1155)
  • Instrumentation library information was added to the Zipkin exporter. (#1119)
  • The SpanProcessor interface now has a ForceFlush() method. (#1166)
  • More semantic conventions for k8s as resource attributes. (#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. (#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. (#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. (#1108)
  • The go.opentelemetry.io/otel/api/trace TracerOption was changed to an interface to conform to project option conventions. (#1109)
  • Move the B3 and TraceContext from within the go.opentelemetry.io/otel/api/trace package to their own go.opentelemetry.io/otel/propagators package.
    This removal of the propagators is reflective of the OpenTelemetry specification for these propagators as well as cleans up the go.opentelemetry.io/otel/api/trace API. (#1118)
  • Rename Jaeger tags used for instrumentation library information to reflect changes in OpenTelemetry specification. (#1119)
  • Rename ProbabilitySampler to TraceIDRatioBased and change semantics to ignore parent span sampling status. (#1115)
  • Move tools package under internal. (#1141)
  • Move go.opentelemetry.io/otel/api/correlation package to go.opentelemetry.io/otel/api/baggage. (#1142)
    The correlation.CorrelationContext propagator has been renamed baggage.Baggage. Other exported functions and types are unchanged.
  • Rename ParentOrElse sampler to ParentBased and allow setting samplers depending on parent span. (#1153)
  • In the go.opentelemetry.io/otel/api/trace package, SpanConfigure was renamed to NewSpanConfig. (#1155)
  • Change dependabot.yml to add a Skip Changelog label to dependabot-sourced PRs. (#1161)
  • The configuration style guide has been updated to
    recommend the use of newConfig() instead of configure(). (#1163)
  • The otlp.Config type has been unexported and changed to otlp.config, along with its initializer. (#1163)
  • Ensure exported interface types include parameter names and update the
    Style Guide to reflect this styling rule. (#1172)
  • Don't consider unset environment variable for resource detection to be an error. (#1170)
  • Rename go.opentelemetry.io/otel/api/metric.ConfigureInstrument to NewInstrumentConfig and
    go.opentelemetry.io/otel/api/metric.ConfigureMeter to NewMeterConfig.
  • ValueObserver instruments use LastValue aggregator by default. (#1165)
  • OTLP Metric exporter supports LastValue aggregation. (#1165)
  • Move the go.opentelemetry.io/otel/api/unit package to go.opentelemetry.io/otel/unit. (#1185)
  • Rename Provider to MeterProvider in the go.opentelemetry.io/otel/api/metric package. (#1190)
  • Rename NoopProvider to NoopMeterProvider in the go.opentelemetry.io/otel/api/metric package. (#1190)
  • Rename NewProvider to NewMeterProvider in the go.opentelemetry.io/otel/api/metric/metrictest package. (#1190)
  • Rename Provider to MeterProvider in the go.opentelemetry.io/otel/api/metric/registry package. (#1190)
  • Rename NewProvider to NewMeterProvider in the go.opentelemetry.io/otel/api/metri/registryc package. (#1190)

  • Rename NoopProvider to NoopTracerProvider in the go.opentelemetry.io/otel/api/trace package. (#1190)
  • Rename Provider to TracerProvider in the go.opentelemetry.io/otel/api/trace/tracetest package. (#1190)
  • Rename NewProvider to NewTracerProvider in the go.opentelemetry.io/otel/api/trace/tracetest package. (#1190)
  • Rename WrapperProvider to WrapperTracerProvider in the go.opentelemetry.io/otel/bridge/opentracing package. (#1190)
  • Rename NewWrapperProvider to NewWrapperTracerProvider in the go.opentelemetry.io/otel/bridge/opentracing package. (#1190)
  • Rename Provider method of the pull controller to MeterProvider in the go.opentelemetry.io/otel/sdk/metric/controller/pull package. (#1190)
  • Rename Provider method of the push controller to MeterProvider in the go.opentelemetry.io/otel/sdk/metric/controller/push package. (#1190)
  • Rename ProviderOptions to TracerProviderConfig in the go.opentelemetry.io/otel/sdk/trace package. (#1190)
  • Rename ProviderOption to TracerProviderOption in the go.opentelemetry.io/otel/sdk/trace package. (#1190)
  • Rename Provider to TracerProvider in the go.opentelemetry.io/otel/sdk/trace package. (#1190)
  • Rename NewProvider to NewTracerProvider in the go.opentelemetry.io/otel/sdk/trace package. (#1190)
  • Renamed SamplingDecision values to comply with OpenTelemetry specification change. (#1192)
  • Renamed Zipkin attribute names from ot.status_code & ot.status_description to otel.status_code & otel.status_description. (#1201)
  • The default SDK now invokes registered SpanProcessors in the order they were registered with the TracerProvider. (#1195)

Removed

  • Remove the B3 propagator from go.opentelemetry.io/otel/propagators. It is now located in the
    go.opentelemetry.io/contrib/propagators/ module. (#1191)
  • Remove the semantic convention for HTTP status text, HTTPStatusTextKey from package go.opentelemetry.io/otel/semconv. (#1194)

Fixed

  • Zipkin example no longer mentions ParentSampler, corrected to ParentBased. (#1171)
  • Fix missing shutdown processor in otel-collector example. (#1186)

Release v0.11.0

Added

  • Noop and InMemory SpanBatcher implementations to help with testing integrations. (#994)
  • Integration tests for more OTel Collector Attribute types. (#1062)
  • A dimensionality-reducing metric Processor. (#1057)
  • Support for filtering metric label sets. (#1047)
  • Support for exporting array-valued attributes via OTLP. (#992)

Changed

  • Rename sdk/metric/processor/test to sdk/metric/processor/processortest. (#1049)
  • Rename sdk/metric/controller/test to sdk/metric/controller/controllertest. (#1049)
  • Rename api/testharness to api/apitest. (#1049)
  • Rename api/trace/testtrace to api/trace/tracetest. (#1049)
  • Change Metric Processor to merge multiple observations. (#1024)
  • The go.opentelemetry.io/otel/bridge/opentracing bridge package has been made into its own module.
    This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038)
  • Renamed go.opentelemetry.io/otel/api/standard package to go.opentelemetry.io/otel/semconv to avoid the ambiguous and generic name standard and better describe the package as containing OpenTelemetry semantic conventions. (#1016)
  • The environment variable used for resource detection has been changed from OTEL_RESOURCE_LABELS to OTEL_RESOURCE_ATTRIBUTES (#1042)
  • Replace WithSyncer with WithBatcher in examples. (#1044)
  • Replace the google.golang.org/grpc/codes dependency in the API with an equivalent go.opentelemetry.io/otel/codes package. (#1046)
  • Merge the go.opentelemetry.io/otel/api/label and go.opentelemetry.io/otel/api/kv into the new go.opentelemetry.io/otel/label package. (#1060)
  • Unify Callback Function Naming.
    Rename *Callback with *Func. (#1061)
  • CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064)

Removed

  • Duplicate, unused API sampler interface. (#999)
    Use the Sampler interface provided by the SDK instead.
  • The grpctrace instrumentation was moved to the go.opentelemetry.io/contrib repository and out of this repository.
    This move includes moving the grpc example to the go.opentelemetry.io/contrib as well. (#1027)
  • The WithSpan method of the Tracer interface.
    The functionality this method provided was limited compared to what a user can provide themselves.
    It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043)
  • The RegisterSpanProcessor and UnregisterSpanProcessor functions.
    These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077)
  • The oterror package. (#1026)
  • The othttp and httptrace instrumentations were moved to go.opentelemetry.io/contrib. (#1032)

Fixed

  • The semconv.HTTPServerMetricAttributesFromHTTPRequest() function no longer generates the high-cardinality http.request.content.length label. (#1031)
  • Correct instrumentation version tag in Jaeger exporter. (#1037)
  • The SDK span will now set an error event if the End method is called during a panic (i.e. it was deferred). (#1043)
  • Move internally generated protobuf code from the go.opentelemetry.io/otel to the OTLP exporter to reduce dependency overhead. (#1050)
  • The otel-collector example referenced outdated collector processors. (#1006)

Release v0.10.0

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)
