 All notable changes to the LaunchDarkly React Native SDK will be documented in this file. This project adheres to [Semantic Versioning](http://semver.org).
 
+## [4.2.1] - 2021-06-01
+### Fixed:
+- iOS: Fixed an issue where an exception was thrown when calling `LDClient.configure` with an optional `timeout` ([#80](https://github.com/launchdarkly/react-native-client-sdk/issues/80)).
+- iOS: Improved consistency with Android for `LDClient.isInitialized`. Both implementations will now reject the promise if the client has not been configured.
+- iOS: Avoid exceptions on iOS when certain methods are called after `LDClient.close`. (Thanks, [andvalsol](https://github.com/launchdarkly/react-native-client-sdk/pull/78))! ([#75](https://github.com/launchdarkly/react-native-client-sdk/issues/75))
+- Android: Fixed an issue where the promise for `LDClient.configure` could be resolved before the client had finished initializing when not providing the optional `timeout` parameter.
+- Android: Fixed an issue where `LDClient.allFlags` would reject the promise when the client was configured but not yet initialized, rather than resolving with any cached flags.
