6.2.1

[6.2.1] - 2021-07-15

Changed:

• If variation or variation_detail is called with a user object that has no key (an invalid condition that will always result in the default value being returned), the SDK now logs a warn-level message to alert you to this incorrect usage. This makes the Ruby SDK's logging behavior consistent with the other server-side LaunchDarkly SDKs. (#177)
