CHANGELOG.md

@@ -21,6 +21,7 @@ This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.htm
   This package is provided with the anticipation that all functionality will be migrate to `go.opentelemetry.io/otel` when `go.opentelemetry.io/otel/log` stabilizes.
   At which point, users will be required to migrage their code, and this package will be deprecated then removed. (#5085)
 - Add support for `Summary` metrics in the `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` and `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` exporters. (#5100)
+- Add `otel.scope.name` and `otel.scope.version` tags to spans exported by `go.opentelemetry.io/otel/exporters/zipkin`. (#5108)
