@@ -17,6 +17,8 @@ This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.htm
 - The `go.opentelemetry.io/contrib/config` package supports configuring `with_resource_constant_labels` for the prometheus exporter. (#5890)
 - Add new runtime metrics to `go.opentelemetry.io/contrib/instrumentation/runtime`, which are still disabled by default. (#5870)
 - Support for the `OTEL_HTTP_CLIENT_COMPATIBILITY_MODE=http/dup` environment variable in `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` to emit attributes for both the v1.20.0 and v1.26.0 semantic conventions. (#5401)
+- Added option for adding default attributes to otel http transport in `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp`. (#5876)
+- Added option for extracting attributes from the http request in http transport in `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp`. (#5876)
