+too disruptive to adopt right away.
+
+### ⚠️⚠️ Breaking changes ⚠️⚠️
+
+- The default OTLP protocol has been changed from `grpc` to `http/protobuf` in order to align with
+  the [specification](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.28.0/specification/protocol/exporter.md#specify-protocol).
+  You can switch to the `grpc` protocol using `OTEL_EXPORTER_OTLP_PROTOCOL=grpc`
+  or `-Dotel.exporter.otlp.protocol=grpc`.
