Unreleased

Added

• WithMetricAttributesFn option in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc to define dynamic attributes on auto-instrumented metrics. (#8191)

Fixed

• Fix panic when passing nil TracerProvider or MeterProvider to WithTracerProvider or WithMeterProvider in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8323)

Removed

• The deprecated DefaultClient, Get, Head, Post, and PostForm in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. Use a custom *http.Client with otelhttp.NewTransport(http.DefaultTransport) instead. (#8266)

1.35.0/0.60.0/0.29.0/0.15.0/0.10.0/0.8.0/0.7.0 - 2025-03-05

This release is the last to support Go 1.22. The next release will require at least Go 1.23.

Warning

This is the last version to use Semantic Conventions v1.20.0 for HTTP libraries by default. The next version (0.61.0) will default to v1.26.0, and the following one (0.62.0) will drop support for Semantic Conventions v1.20.0

You can switch to the new Semantic Conventions right now by setting the OTEL_SEMCONV_STABILITY_OPT_IN=http/dup environment variable in your application.
