[5.6.7] - 2022-01-28

When using allFlagsState to produce bootstrap data for the JavaScript SDK, the Java SDK was not returning the correct metadata for evaluations that involved an experiment. As a result, the analytics events produced by the JavaScript SDK did not correctly reflect experimentation results.
In feature flag rules using the before and after date operators, if two ISO-8601 string values were compared that represented the exact same absolute date in different time zones (such as 2000-01-01T08:00:00Z and 2000-01-01T00:00:00-08:00), the SDK wrongly treated them as unequal. This did not affect strings that represented different absolute dates, which were always compared correctly. The SDK now handles both cases correctly.
The com.launchdarkly.sdk.json serialization methods were sometimes omitting JSON object properties in cases where it would have been more correct to show the property with a null value. This mainly affected JSON data produced by LDClient.allFlagsState(), where the presence of a flag key with a null value would indicate that the flag existed but could not be evaluated due to an error, as opposed to the flag not existing.
