Overview

Added

• Add the new go.opentelemetry.io/contrib/detectors/azure/azurevm package to provide a resource detector for Azure VMs. (#5422)
• Add support to configure views when creating MeterProvider using the config package. (#5654)
• The go.opentelemetry.io/contrib/config add support to configure periodic reader interval and timeout. (#5661)
• Add log support for the autoexport package. (#5733)
• Add support for disabling the old runtime metrics using the OTEL_GO_X_DEPRECATED_RUNTIME_METRICS=false environment variable. (#5747)
• Add support for signal-specific protocols environment variables (OTEL_EXPORTER_OTLP_TRACES_PROTOCOL, OTEL_EXPORTER_OTLP_LOGS_PROTOCOL, OTEL_EXPORTER_OTLP_METRICS_PROTOCOL) in go.opentelemetry.io/contrib/exporters/autoexport. (#5816)
• The go.opentelemetry.io/contrib/processors/minsev module is added.
  This module provides and experimental logging processor with a configurable threshold for the minimum severity records must have to be recorded. (#5817)
• The go.opentelemetry.io/contrib/processors/baggagecopy module.
  This module is a replacement of go.opentelemetry.io/contrib/processors/baggage/baggagetrace. (#5824)

Changed

• Improve performance of go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc with the usage of WithAttributeSet() instead of WithAttribute(). (#5664)
• Improve performance of go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp with the usage of WithAttributeSet() instead of WithAttribute(). (#5664)
• Update go.opentelemetry.io/contrib/config to latest released configuration schema which introduces breaking changes where Attributes is now a map[string]interface{}. (#5758)
• Upgrade all dependencies of go.opentelemetry.io/otel/semconv/v1.25.0 to go.opentelemetry.io/otel/semconv/v1.26.0. (#5847)

Fixed

• Custom attributes targeting metrics recorded by the go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp are not ignored anymore. (#5129)
• The double setup in go.opentelemetry.io/contrib/instrumentation/net/http/httptrace/otelhttptrace/example that caused duplicate traces. (#5564)
• The superfluous response.WriteHeader call in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp when the response writer is flushed. (#5634)
• Use c.FullPath() method to set http.route attribute in go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin. (#5734)
• Out-of-bounds panic in case of invalid span ID in go.opentelemetry.io/contrib/propagators/b3. (#5754)

Deprecated

• The go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho package is deprecated.
  If you would like to become a Code Owner of this module and prevent it from being removed, see #5550. (#5645)
• The go.opentelemetry.io/contrib/instrumentation/gopkg.in/macaron.v1/otelmacaron package is deprecated.
  If you would like to become a Code Owner of this module and prevent it from being removed, see #5552. (#5646)
• The go.opentelemetry.io/contrib/samplers/aws/xray package is deprecated.
  If you would like to become a Code Owner of this module and prevent it from being removed, see #5554. (#5647)
• The go.opentelemetry.io/contrib/processors/baggage/baggagetrace package is deprecated.
  Use the added go.opentelemetry.io/contrib/processors/baggagecopy package instead. (#5824)
  • Use baggagecopy.NewSpanProcessor as a replacement for baggagetrace.New.
    • NewSpanProcessor accepts a Fitler function type that selects which baggage members are added to a span.
    • NewSpanProcessor returns a *baggagecopy.SpanProcessor instead of a trace.SpanProcessor interface.
      The returned type still implements the interface.

• Add "go.opentelemetry.io/contrib/samplers/jaegerremote".WithSamplingStrategyFetcher which sets custom fetcher implementation. (#4045)
• Add "go.opentelemetry.io/contrib/config" package that includes configuration models generated via go-jsonschema. (#4376)
• Add NewSDK function to "go.opentelemetry.io/contrib/config". The initial implementation only returns noop providers. (#4414)
• Add metrics support (No-op, OTLP and Prometheus) to go.opentelemetry.io/contrib/exporters/autoexport. (#4229, #4479)
• Add support for console span exporter and metrics exporter in go.opentelemetry.io/contrib/exporters/autoexport. (#4486)
• Set unit and description on all instruments in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#4500)
• Add metric support for grpc.StatsHandler in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#4356)
• Expose the name of the scopes in all instrumentation libraries as ScopeName. (#4448)

Changed

• Dropped compatibility testing for [Go 1.19].
  The project no longer guarantees support for this version of Go. (#4352)
• Upgrade dependencies of OpenTelemetry Go to use the new v1.20.0/v0.43.0 release. (#4546)
• In go.opentelemetry.io/contrib/exporters/autoexport, Option was renamed to SpanOption. The old name is deprecated but continues to be supported as an alias. (#4229)

Deprecated

• The interceptors (UnaryClientInterceptor, StreamClientInterceptor, UnaryServerInterceptor, StreamServerInterceptor, WithInterceptorFilter) are deprecated. Use stats handlers (NewClientHandler, NewServerHandler) instead. (#4534)

Fixed

• The go.opentelemetry.io/contrib/samplers/jaegerremote sampler does not panic when the default HTTP round-tripper (http.DefaultTransport) is not *http.Transport. (#4045)
• The UnaryServerInterceptor in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc now sets gRPC status code correctly for the rpc.server.duration metric. (#4481)
• The NewClientHandler, NewServerHandler in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc now honor otelgrpc.WithMessageEvents options. (#4536)
• The net.sock.peer.* and net.peer.* high cardinality attributes are removed from the metrics generated by go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#4322)

Release v1.20.0/v0.45.0/v0.14.0

Added

• Set the description for the rpc.server.duration metric in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#4302)
• Add NewServerHandler and NewClientHandler that return a grpc.StatsHandler used for gRPC instrumentation in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#3002)
• Add new Prometheus bridge module in go.opentelemetry.io/contrib/bridges/prometheus. (#4227)

Changed

• Upgrade dependencies of OpenTelemetry Go to use the new v1.19.0/v0.42.0/v0.0.7 release.
• Use grpc.StatsHandler for gRPC instrumentation in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc/example. (#4325)

New Contributors

• @puckpuck made their first contribution in #4302
