 ## v6.10.0
 
-- Port names have been updated on services and pods, to unblock Kubernetes service meshes from auto-configuring themselves for the traffic type, since most inter-pod communication has been switched from http to gRPC [[PR 756](https://github.com/sourcegraph/deploy-sourcegraph-helm/pull/756)]. If you are using Istio (or similar service meshes), and [our Envoy filter example](https://github.com/sourcegraph/deploy-sourcegraph-helm/tree/main/charts/sourcegraph/examples/envoy), and your pods fail to communicate after upgrading >= v6.10, please remove the Envoy filter and try again, so your service mesh can auto-configure itself based on the new port names.
