on GitHub

Added

• Add the new go.opentelemetry.io/contrib/instrgen package to provide auto-generated source code instrumentation. (#3068, #3108)
• 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)
