2.1.0

[2.1.0] - 2019-12-23

Added:

• Implemented variationDetail which returns an Evaluation Reason giving developers greater insight into why a value was returned.
• Added allFlagsListener method, this returns flag keys whenever any flag key is updated.
• Added metricValue parameter to track method.
• The Connection Status API allows greater introspection into the current LaunchDarkly connection and the health of local flags.
  • This feature adds a new method called getConnectionInformation that returns an object that contains the current connection mode e.g. streaming or polling, when and how a connection failed, and the last time flags were updated.
  • Additionally, a new observer function called registerCurrentConnectionModeListener allows your application to listen to changes in the SDK's connection to LaunchDarkly.
• A close() method which flushes the event queue and closes all open connections to LaunchDarkly. This method should be invoked as part of your application's termination lifecycle event.

Changed:

• Updated the iOS SDK to version 4.3.2. This enables the removal of use_frameworks! from the Podfile in a project using the LaunchDarkly React Native SDK.
• Updated the Android SDK to version 2.9.0.
• Switched iOS user switching from the deprecated user object to the identify method.
