+- A ConfigMap to provide configuration to the gRPC adapter
+  ([#164](https://github.com/3scale/3scale-istio-adapter/pull/164))
+    * A configuration option to the gRPC server (`USE_CACHED_BACKEND`) to enable the authorization cache.
+    * A configuration option to the gRPC server (`BACKEND_CACHE_FLUSH_INTERVAL_SECONDS`) to set the interval at which metrics get reported from the cache to 3scale.
+    * A configuration option to the gRPC server (`BACKEND_CACHE_POLICY_FAIL_CLOSED`) to determine the fate of a request if 3scale Apisonator is unreachable.
