 * Loggers are removed. The [`interceptors/logging`](interceptors/logging) got simplified and writing adapter for each logger is straightforward. For convenience, we will maintain examples for popular providers in [`interceptors/logging/examples`](interceptors/logging/examples), but those are meant to be copied, not imported.
 * `grpc_opentracing` interceptor was removed. This is because tracing instrumentation evolved. OpenTracing is deprecated and OpenTelemetry has now a [superior tracing interceptor](https://go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc).
 * `grpc_ctxtags` interceptor was removed. Custom tags can be added to logging fields using `logging.InjectFields`. Proto option to add logging field was clunky in practice and we don't see any use of it nowadays, so it's removed.
-* One of the most powerful interceptor was imported from https://github.com/grpc-ecosystem/go-grpc-prometheus (repo is now deprecated). This consolidation allows easier maintenance, easier use and consistent API.
+* One of the most powerful interceptor was imported from https://github.com/grpc-ecosystem/go-grpc-prometheus (repo is now deprecated). This consolidation allows easier maintenance, easier use and consistent API. **No metrics name or labels changed**, so you all dashboards, alerts and integrations will be unaffected.
 * Chain interceptors was removed, because `grpc` implemented one.
 * Moved to the new proto API (google.golang.org/protobuf).
 * All "deciders", so functions that decide what to do based on gRPC service name and method (aka "fullMethodName") are removed (!). Use [`github.com/grpc-ecosystem/go-grpc-middleware/v2/interceptors/selector`](interceptors/selector) interceptor to select what method, type or service should use what interceptor.
