+# 1. General Notes
+* General
+  - Carter intro
+  - New Moile SDKs in the works: v1.6.0 on Android & 0.16 on iOS
+  - Currently the Client App resources are setting custom checkpoints - SDK can take care of auto checkpoint updates on version releases

+  - iOS Synchronizer pending issue:  when users are backgrounding the app and they resume - GRPC channel dying and not resuming as expected and then the app errors out
+  - Android crashes when networking errors out when the app in the background
+  - GRPC team is in touch with ECC devs for advice on how to use the APIs for native apps
+  - Bumping up minimum Android API to iOS 13, to have a coroutines equivalent on iOS
+  - iOS ZcashLightClientKit 0.16 will include changes on the Birthday API
+  - Additional changes on cleaning up the Oublic API for being more type-safe usages around Zatoshi object & memo encoding.
+  - Upcoming large effort - changes with Unified Address will be major, possibly breaking.
