 Async Storage v3
+
+Initial release of upcoming version v3.
+Please visit [Async Storage docs to learn more](https://react-native-async-storage.github.io/)
+
+## Breaking changes:
+
+- Async Storage uses "scoped storages", where you need to create a storage instance before using it
+- Default export is a singleton storage that uses v2/v1 storage, for easier transition
+- An extra installation step is required for android
+- `callback` based API is dropped
+- Methods for batch operations (formerly `multi*` methods) have been renamed and their API updated
+- `useAsyncStorage` hook has been removed (will be introduced later)
+- Updated Native side (Brownfield) access to storage - dropped apple's delegate
+- Dropped a flag to opt out from iCloud backup - disabled by default now
