Added

• Add environment variables propagation carrier in go.opentelemetry.io/contrib/propagators/envcar. (#8442)

Changed

• Upgrade go.opentelemetry.io/otel/semconv to v1.40.0, including updates across instrumentation and detector modules. (#8631)

  • The semantic conventions v1.40.0 release introduces RPC breaking changes applied in this repository:
    • RPC spans and metrics no longer include network.protocol.name, network.protocol.version, or network.transport attributes.
    • rpc.client.request.size, rpc.client.response.size, rpc.server.request.size, and rpc.server.response.size are no longer emitted in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc.
    • rpc.message span events and their message attributes are no longer emitted in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc (including when WithMessageEvents is configured).

  See semantic-conventions v1.40.0 release for complete details.

Fixed

• Ignore informational response status codes (100-199) except 101 Switching Protocols when storing the HTTP status code in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp and go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux. (#6913)
• Make Body handling in Transport consistent with stdlib in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#8618)
• Fix bucket boundaries for rpc.server.call.duration and rpc.client.call.duration in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8642)
• Host resource detector in go.opentelemetry.io/contrib/otelconf now includes os. attributes. (#8578)

Removed

• Drop support for Go 1.24. (#8628)
