[4.3.0] - 2018-08-27

The new LDClient method allFlagsState() should be used instead of allFlags() if you are passing flag data to the front end for use with the JavaScript SDK. It preserves some flag metadata that the front end requires in order to send analytics events correctly. Versions 2.5.0 and above of the JavaScript SDK are able to use this metadata, but the output of allFlagsState() will still work with older versions.
The allFlagsState() method also allows you to select only client-side-enabled flags to pass to the front end, by using the option FlagsStateOption.CLIENT_SIDE_ONLY. (#112)
The new LDClient methods boolVariationDetail, intVariationDetail, doubleVariationDetail, stringVariationDetail, and jsonVariationDetail allow you to evaluate a feature flag (using the same parameters as you would for boolVariation, etc.) and receive more information about how the value was calculated. This information is returned in an EvaluationDetail object, which contains both the result value and an EvaluationReason which will tell you, for instance, if the user was individually targeted for the flag or was matched by one of the flag's rules, or if the flag returned the default value due to an error.

Fixed a bug in LDUser.Builder that would throw an exception if you initialized the builder by copying an existing user, and then tried to add a custom attribute.
