+- Updated the NDC TypeScript SDK to v7.0.0 ([#44](https://github.com/hasura/ndc-nodejs-lambda/pull/44))
+  - Added support for exporting OpenTelemetry traces and metrics over GRPC. A new environment variable `OTEL_EXPORTER_OTLP_PROTOCOL` lets you switch between `http/protobuf` and `grpc`.

+  - To return to the old defaults, set the following environment variables:
