 All notable changes to the LaunchDarkly client-side JavaScript SDKs will be documented in this file. This project adheres to [Semantic Versioning](http://semver.org).
 
+## [2.17.1] - 2020-03-06
+### Fixed:
+- At client initialization time, if the initial flag polling request failed, it would cause an unhandled promise rejection unless the application had called `waitForInitialization()` and provided an error handler for the promise that was returned by that method. While that is correct behavior if the application did call `waitForInitialization()` (any promise that might be rejected should have an error handler attached), it is inappropriate if the application did not call `waitForInitialization()` at all-- which is not mandatory, since the application could use events instead, or `waitUntilReady()`, or might simply not care about waiting for initialization. This has been fixed so that no such promise is created until the first time the application calls `waitForInitialization()`; subsequent calls to the same method will return the same promise (since initialization can only happen once).
+- A bug in the event emitter made its behavior unpredictable if an event handler called `on` or `off` while handling an event. This has been fixed so that all event handlers that were defined _at the time the event was fired_ will be called; any changes made will not take effect until the next event.

 ## [2.17.0] - 2020-02-14
 Note: if you are using the LaunchDarkly Relay Proxy to forward events, update the Relay to version 5.10.0 or later before updating to this Node SDK version.
