+Async Storage v3
+
+## General changes
+- Async Storage now provides a way to create isolated data storages, so your data does is not stored in "one bucket"
+- Default export is now a proxy to the legacy v2 implementation for gradual migration
+- You must now create storages using `createAsyncStorage(name)` — no default global storage instance
+- New website
+
+## Breaking Changes:
+
+- Android requires a `repositories.maven` added in project's `build.gradle`
+- You must now create storages using `createAsyncStorage(name)` — no default global storage instance.
+- `multiGet`, `multiSet`, and `multiRemove` renamed to `getMany`, `setMany`, and `removeMany`
+- The "multi" methods now accept object maps ({ key: value }) instead of arrays of pairs ([[key, value]])
+- `mergeItem` and `multiMerge` have been removed
+- `useAsyncStorage` hook has been removed
+- Methods now throw `AsyncStorageError` instead of using callbacks for error handling.
+- New Brownfield access (replaced delegate on iOS) for native platforms
+- iCloud backup exclusion flag removed (storage is excluded by default).
+- Web backend switched to IndexedDB
