 **This project is in the Beta stage. The API should be quite stable, but occasional breaking changes may be made.**

 ### Enhancements
 * Added `DisconnectedSyncConfiguration` for opening a synchronized realm in a disconnected state. This configuration allows a synchronized realm to be opened by a secondary process, while a primary process handles synchronization. ([#621](https://github.com/realm/realm-dart/pull/621))
 * Support better default paths on Flutter. ([#665](https://github.com/realm/realm-dart/pull/665))
 * Support `Configuration.defaultRealmName` for setting the default realm name. ([#665](https://github.com/realm/realm-dart/pull/665))
 * Support `Configuration.defaultRealmPath` for setting a custom default path for realms. ([#665](https://github.com/realm/realm-dart/pull/665))
 * Support `Configuration.defaultStoragePath ` for getting the platform specific storage paths. ([#665](https://github.com/realm/realm-dart/pull/665))
+* Support `App.deleteUser ` for deleting user accounts. ([#679](https://github.com/realm/realm-dart/pull/679))
