+- New config settings for minimumFetchInterval and fetch timeout.
+- Async activate API with completion handler.
+
+Version 4.0.0
+==================================
+- FirebaseAnalytics is no longer a hard dependency in the RemoteConfig pod. If you were installing Remote Config via pod ''Firebase/RemoteConfig'', you should add 'pod 'Firebase/Analytics'' to the Podfile to maintain full RemoteConfig functionality.
