Release v1.6.0/v0.31.0

Added

• The project is now tested against Go 1.18 (in addition to the existing 1.16 and 1.17) (#1976)

Changed

• Upgraded all dependencies on stable modules from go.opentelemetry.io/otel from v1.5.0 to v1.6.1. (#2134)
• Upgraded all dependencies on metric modules from go.opentelemetry.io/otel from v0.27.0 to v0.28.0. (#1977)

Release v1.5.0/v0.30.0/v0.1.0

Added

• Added the go.opentelemetry.io/contrib/samplers/jaegerremote package.
  This package implements the Jaeger remote sampler for OpenTelemetry Go. (#936)
• DynamoDB spans created with the go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws package now have the appropriate database attributes added for the operation being performed.
  These attributes are detected automatically, but it is also now possible to provide a custom function to set attributes using WithAttributeSetter. (#1582)
• Add resource detector for GCP cloud function. (#1584)
• Add OpenTracing baggage extraction to the OpenTracing propagator in go.opentelemetry.io/contrib/propagators/ot. (#1880)

Fixed

• Fix the echo middleware by using SpanKind.SERVER when deciding the SpanStatus.
  This makes 4xx response codes to not be an error anymore. (#1848)

Removed

• The deprecated go.opentelemetry.io/contrib/exporters/metric/datadog module is removed. (#1920)
• The deprecated go.opentelemetry.io/contrib/exporters/metric/dogstatsd module is removed. (#1920)
• The deprecated go.opentelemetry.io/contrib/exporters/metric/cortex module is removed.
  Use the go.opentelemetry.io/otel/exporters/otlp/otlpmetric exporter as a replacement to send data to a collector which can then export with its PRW exporter. (#1920)

Release v1.4.0/v0.29.0

Added

• Add WithClientTrace option to go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#875)

Changed

• All metric instruments from the go.opentelemetry.io/contrib/instrumentation/runtime package have been renamed from runtime.go.* to process.runtime.go.* so as to comply with OpenTelemetry semantic conventions. (#1549)

Fixed

• Change the http-server-duration instrument in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp to record milliseconds instead of microseconds. This changes fixes the code to comply with the OpenTelemetry specification. (#1414, #1537)
• Fixed the region reported by the "go.opentelemetry.io/contrib/detectors/gcp".CloudRun detector to comply with the OpenTelemetry specification. It no longer includes the project scoped region path, instead just the region. (#1546)
• The "go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp".Transport type now correctly handles protocol switching responses. The returned response body implements the io.ReadWriteCloser interface if the underlying one does. This ensures that protocol switching requests receive a response body that they can write to. (#1329, #1628)

Deprecated

• The go.opentelemetry.io/contrib/exporters/metric/datadog module is deprecated. (#1639)
• The go.opentelemetry.io/contrib/exporters/metric/dogstatsd module is deprecated. (#1639)
• The go.opentelemetry.io/contrib/exporters/metric/cortex module is deprecated. Use the go.opentelemetry.io/otel/exporters/otlp/otlpmetric exporter as a replacement to send data to a collector which can then export with its PRW exporter. (#1639)

Removed

• Remove the MinMaxSumCount from cortex and datadog exporter. (#1554)
• The go.opentelemetry.io/contrib/exporters/metric/dogstatsd exporter no longer support exporting histogram or exact data points. (#1639)
• The go.opentelemetry.io/contrib/exporters/metric/datadog exporter no longer support exporting exact data points. (#1639)

Release v1.3.0/v0.28.0

⚠️ Notice ⚠️

We have updated the project minimum supported Go version to 1.16

Changed

• otelhttptrace.NewClientTrace now uses TracerProvider from the parent context if one exists and none was set with WithTracerProvider (#874)

Fixed

• The "go.opentelemetry.io/contrib/detector/aws/ecs".Detector no longer errors if not running in ECS. (#1428)
• go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux does not require instrumented HTTP handlers to call Write nor WriteHeader anymore. (#1443)

Release v1.2.0/v0.27.0

Changed

• Update dependency on the go.opentelemetry.io/otel project to v1.2.0.
• go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-lambda-go/otellambda/xrayconfig
  updated to ensure access to the TracerProvider.
  • A NewTracerProvider() function is available to construct a recommended
    TracerProvider configuration.
  • AllRecommendedOptions() has been renamed to WithRecommendedOptions()
    and takes a TracerProvider as an argument.
  • EventToCarrier() and Propagator() are now WithEventToCarrier() and
    WithPropagator() to reflect that they return Option implementations.

Release v1.1.1/v0.26.1

[1.1.1/0.26.1] - 2021-11-04

Changed

• The Transport, Handler, and HTTP client convenience wrappers in the go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp package now use the TracerProvider from the parent context if one exists and none was explicitly set when configuring the instrumentation. (#873)
• Semantic conventions now use go.opentelemetry.io/otel/semconv/v1.7.0". (#1385)

Release v1.1.0/v0.26.0

• Add resource detector for AWS Lambda. (#983)
• Add WithTracerProvider option for otelhttptrace.NewClientTrace. (#1128)
• Add optional AWS X-Ray configuration module for AWS Lambda Instrumentation (#984)

Fixed

• The go.opentelemetry.io/contrib/propagators/ot propagator returns the words true or false for the ot-tracer-sampled header instead of numerical 0 and 1. (#1358)
