Upgrades all go.opentelemetry.io/otel dependencies to v1.9.0.

Added

• The TextMapPropagator function to go.opentelemetry.io/contrib/propagators/autoprop. This function is used to return a composite TextMapPropagator from registered names (instead of having to specify with an environment variable). (#2593)

Release v1.8.0/v0.33.0/v0.3.0

1.8.0/0.33.0 - 2022-07-08

Added

• The go.opentelemetry.io/contrib/propagators/autoprop package to provide configuration of propagators with useful defaults and envar support. (#2258)
• WithPublicEndpointFn hook to dynamically detect public HTTP requests and set their trace parent as a link. (#2342)

Fixed

• Fix the otelhttp, otelgin, otelmacaron, otelrestful middlewares
  by using SpanKindServer when deciding the SpanStatus.
  This makes 4xx response codes to not be an error anymore. (#2427)

Release v1.7.0/v0.32.0/v0.2.0

Added

• Consistent probability sampler implementation. (#1379)
• AWS X-Ray remote sampling support. (#1859)

Changed

• Upgraded all semconv package use to v1.10.0. This includes a backwards incompatible change for the otelgocql package to conform with the specification change. The db.cassandra.keyspace attribute is now transmitted as the db.name attribute. (#2222)

Fixed

• Fix the otelmux middleware by using SpanKindServer when deciding the SpanStatus. This makes 4xx response codes to not be an error anymore. (#1973)
• Fixed jaegerremote sampler not behaving properly with per operation strategy set. (#2137)
• Stopped injecting propagation context into response headers in otelhttp. (#2180)

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)
