v1.46.0/v2.5.3/v0.71.0/v0.37.3/v0.26.0/v0.20.1/v0.16.3/v0.18.0

This release is the last to support Go 1.25.
The next release will require at least Go 1.26.

Added

• Add support for the aws.ec2 resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9139)
• Support testing of Go 1.27. (#9524)
• Add go.opentelemetry.io/contrib/detectors/docker, a resource detector for Docker, ported from processor/resourcedetectionprocessor/internal/docker in opentelemetry-collector-contrib. (#9001)
• Add S3AttributeBuilder to go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws that sets S3-specific span attributes following the OpenTelemetry S3 semantic conventions. (#9292)
• Add go.opentelemetry.io/contrib/detectors/docker, a resource detector for Docker, ported from processor/resourcedetectionprocessor/internal/docker in opentelemetry-collector-contrib. (#9001)

Deprecated

• Deprecate go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho.
  Use github.com/labstack/echo-opentelemetry instead. (#9136)

Fixed

• Record error.type attribute on server spans in go.opentelemetry.io/contrib/instrumentation/github.com/emicklei/go-restful/otelrestful when a request is cancelled or ends in a 5xx error. (#9387)
• Report ot-baggage-* extraction errors from go.opentelemetry.io/contrib/propagators/ot to otel.Handle instead of silently discarding them, while still attaching the successfully parsed baggage members to the context. (#9395)
• Set error.type on the rpc.client.call.duration and rpc.server.call.duration metrics in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc when the RPC fails with a non-OK status, per the RPC semantic conventions. (#9429)
• Reject OTLP exporter headers with an empty name in go.opentelemetry.io/contrib/otelconf, go.opentelemetry.io/contrib/otelconf/x, and go.opentelemetry.io/contrib/otelconf/v0.3.0, instead of forwarding invalid header names to OTLP exporters. (#9102)
• go.opentelemetry.io/contrib/detectors/aws/lambda no longer returns an error when run outside of an AWS Lambda environment, matching the no-op behavior of other resource detectors. (#9464)
• Convert Prometheus untyped metrics to OTLP Gauges in go.opentelemetry.io/contrib/bridges/prometheus. (#9099)
