1.33.1

💥 Breaking Changes

• fix: Remove the subset of DB_SYSTEM_NAME_VALUE_* exports that are unstable from the @opentelemetry/semantic-conventions entry point. #5690
  • Version 1.33.0 erroneously included all DB_SYSTEM_NAME_VALUE_* constants in the stable entry point. Some of those enum values are not yet stable. They have been moved back to the unstable @opentelemetry/semantic-conventions/incubating entry point. See the PR description for a full list.

experimental/v0.201.1

0.201.1

🐛 Bug Fixes

• fix(instrumentation): Change SemconvStability export from const enum to enum to allow single-file transpilation tooling to work with code that uses SemconvStability. #5691 @trentm

v2.0.1

2.0.1

🐛 Bug Fixes

• fix(resources): guard asynchronous resource attribute rejections from causing unhandled promise rejection #5544 @dyladan
• fix(resource): do not trigger Accessing resource attributes before async attributes settled warning when detecting resources #5546 @dyladan
  • verbose logging of detected resource removed
• fix(resource): use dynamic import over require to improve ESM compliance #5298 @xiaoxiangmoe

experimental/v0.201.0

0.201.0

🚀 Features

• feat(instrumentation-xml-http-request): support migration to stable HTTP semconv, v1.23.1 #5662 @trentm
  • Configure the instrumentation with semconvStabilityOptIn: 'http' to use the new, stable semconv v1.23.1 semantics or 'http/dup' for both old (v1.7.0) and stable semantics. When semconvStabilityOptIn is not specified (or does not contain these values), it uses the old semconv v1.7.0. I.e. the default behavior is unchanged.
• feat(instrumentation-fetch): support migration to stable HTTP semconv, v1.23.1 #5651 @trentm
  • Configure the instrumentation with semconvStabilityOptIn: 'http' to use the new, stable semconv v1.23.1 semantics or 'http/dup' for both old (v1.7.0) and stable semantics. When semconvStabilityOptIn is not specified (or does not contain these values), it uses the old semconv v1.7.0. I.e. the default behavior is unchanged.
• feat(instrumentation): New semconvStabilityFromStr() utility for semconv stability migration in instrumentations. #5684 @trentm
  • See the utility comment.
• feat(instrumentation-grpc): support migration to stable HTTP semconv #5653 @JamieDanielson
• feat(instrumentation-http): capture synthetic source type on requests #5488 @JacksonWeber

🐛 Bug Fixes

• fix(otlp-transformer): do not throw when deserializing empty JSON response #5551 @pichlermarc
• fix(instrumentation-http): report stable client metrics response code #9586 @jtescher
• fix(sdk-node): instantiate baggage processor when env var is set #5634 @pichlermarc

🏠 Internal

• refactor(instrumentation-http): Remove legacy http span attributes and metrics #5552 @svetlanabrennan
• refactor(instrumentation-http): Add back support for http semconv #5665 @JamieDanielson
  • Note: We initially removed support for legacy http attributes and metrics, but then added back for an additional 6 months to ensure all instrumentations could be updated and kept consistent. There should be no net new change in this instrumentation related to these semantic conventions. See #5646 for details.
• refactor(sdk-node): update semconv usage to ATTR_ exports #5668 @trentm
• chore(sdk-node): Refactored using get*FromEnv utility function instead of process.env for NodeSDK's resource detector setup. #5582 @beeme1mr
• chore(sdk-node): Refactored using get*FromEnv utility function instead of process.env for NodeSDK's logging setup. #5563 @weyert

• feat(sdk-metrics)!: extract IMetricReader interface and use it over abstract class #5311
  • (user-facing): MeterProviderOptions now provides the more general IMetricReader type over MetricReader
  • If you accept MetricReader in your public interface, consider accepting the more general IMetricReader instead to avoid unintentional breaking changes
• feat(sdk-trace)!: remove ability to have BasicTracerProvider instantiate exporters #5239 @pichlermarc
  • When extending BasicTracerProvider, the class offered multiple methods to facilitate the creation of exporters and auto-pairing with SpanProcessors.
    • This functionality has been removed - users may now pass SpanProcessors to the base class constructor when extending
    • (user-facing): _registeredExporters has been removed
    • (user-facing): _getSpanExporter has been removed
    • (user-facing): _buildExporterFromEnv has been removed
• feat(core)!: remove deprecated IdGenerator and RandomIdGenerator #5309 @pichlermarc

  • (user-facing): deprecated TraceIdRatioSampler has moved to @opentelemetry/sdk-trace-base
• feat(resource): Merge sync and async resource interfaces into a single interface #5350 @dyladan
  • Resource constructor now takes a single argument which contains an optional attributes object
  • Detected resource attribute values may be a promise or a synchronous value
  • Resources are now merged by the order in which their detectors are configured instead of async attributes being last

    • propagators can now not be configured via OTEL_PROPAGATORS or window.OTEL_PROPAGATORS anymore, please pass the propagator to NodeTracerProvider#register() instead.
    • if not configured directly via code, BasicTracerProvider#register() will now fall back to defaults (tracecontext and baggage)
• feat(sdk-trace-node)!: drop ability to instantiate propagators beyond defaults #5355 @pichlermarc
  • (user-facing): only a non-env-var based default is now used on NodeTracerProvider#register().
    • propagators can now not be configured via OTEL_PROPAGATORS anymore, please pass the propagator to NodeTracerProvider#register() instead.
    • if not configured via code, NodeTracerProvider#register() will now fall back to the defaults (tracecontext and baggage)
    • if autoconfiguration based on enviornment variables is needed, please use NodeSDK from @opentelemetry/sdk-node.
• feat(sdk-trace-web)!: drop ability to instantiate propagators beyond defaults #5355 @pichlermarc
  • (user-facing): only a non-env-var based default is now used on WebTracerProvider#register().
