+### Add gRPC's binary metadata support [#3234](https://github.com/grafana/k6/pull/3234), [xk6-grpc#46](https://github.com/grafana/xk6-grpc/pull/46)
+
+By specification gRPC metadata with the `-bin` postfix should be treated as binary data. These PRs add the support of such metadata to the `k6/net/grpc` and `k6/experimental/grpc` modules.
+
+```js
+let resp = client.invoke("grpc.testing.TestService/EmptyCall", {}, { metadata: { "X-Load-Tester-bin": new Uint8Array([2, 200]) } })
+```
+
+Thanks, @sapphire-janrain, for contribution!
+
+### Add the reflection metadata [#3343](https://github.com/grafana/k6/pull/3343), [xk6-grpc#46](https://github.com/grafana/xk6-grpc/pull/46)
+
+In some workflows the reflection call should also include some metadata. This PR adds [a new connection parameter `reflectMetadata`](https://k6.io/docs/javascript-api/k6-net-grpc/client/client-connect/#connectparams) that allows to specify the metadata to be sent with the reflection call.
