 * Feat: [Web] Update internal [CallStatus] mapping method.
 * Fix: [Web] Await Twilio Device `register()` and `unregister()` method calls.
 * Fix: [Web] Prevent duplicate `TwilioVoiceWeb` instances.
+* Feat: [iOS] Add support for call logging via `enableCallLogging(bool)` to record call in recents. No other platform currently supports this, see [NOTES.md](NOTES.md#limitations) for more details.

 ## Limitations
 
+### Android
+
+Android `ConnectionService` provides the fundamentals to managing calls, including but not limited to call logging. Using a Managed `ConnectionService` means that call logging is handled by the system's "Phone App", and so there is not access or control over call logging at this time.
+
 ### macOS
 
-Clearly, macOS isn't uppermost in mind when looking at a mobile first platform like Flutter. There are some functionality limitations for the platform/interop such as [UIImage](https://docs.flutter.dev/ui/assets-and-images#loading-ios-images-in-flutter) support and Twilio Voice library support as a whole. Hopefully we'll be seeing these implemented in future.

+
+With respect to CallKit integration for macOS, there isn't any direct support for CallKit other than via MacCatalyst which at present is somewhat out of scope for the project at this time.
+
+
+### Web
+
+As Web uses a custom [WebCallkit](https://github.com/cybex-dev/web_callkit) integration, this facilitates basic call management and browser notification integration. Call logging is not supported at this time.
