 All notable changes to the LaunchDarkly React Native SDK will be documented in this file. This project adheres to [Semantic Versioning](http://semver.org).
 
+## [4.2.0] - 2021-05-19
+### Added:
+- `LDUser` now has an optional `secondary` attribute to match other LaunchDarkly SDKs. For more on the behavior of this attribute see [the documentation on targeting users](https://docs.launchdarkly.com/home/managing-flags/targeting-users).
+- Support for multiple LaunchDarkly projects or environments. Each set of feature flags associated with a mobile key is called an environment. ([#10](https://github.com/launchdarkly/react-native-client-sdk/issues/10))
+  - `secondaryMobileKeys` is now a config option which allows a mapping of names to the SDK keys for each additional environment. `mobileKey` is still required, and represents the primary environment.
+  - Many methods including variations, track, and listeners now support an optional `environment` parameter to evaluate the method against the given `environment`.

 ## [4.1.2] - 2021-04-28
 ### Fixed:
 - The `LDEvaluationReasonErrorKind`, `LDEvaluationReasonKind`, `LDConnectionMode`, and `LDFailureReason` enum TypeScript types were undefined when evaluated at runtime due to being defined in an ambient context. This was also fixed in SDK version 4.0.3 with React Native 0.63 compatibility.
