 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).
 
+## [2.17.2] - 2020-03-18
+### Fixed:
+- Some users reported an error where the SDK said that the content type of a response was `application/json, application/json; charset=utf8`. It is invalid to have multiple Content-Type values in a response and the LaunchDarkly service does not do this, but an improperly configured proxy/gateway might add such a header. Now the SDK will tolerate a value like this as long as it starts with `application/json`. ([#205](https://github.com/launchdarkly/js-client-sdk/issues/205))
+- Fixed incorrect usage of `Object.hasOwnProperty` which could have caused an error if a feature flag had `hasOwnProperty` as its flag key.
+
 ## [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).
