User settings
Contexts are now available
After you have upgraded your LaunchDarkly SDK to use contexts instead of users, you should use Contexts instead of the user settings API. To learn more, read Contexts.
LaunchDarkly’s user settings API provides a picture of all feature flags and their current values for a specific user. This gives you instant visibility into how a particular user experiences your site or application. To learn more, read View and manage contexts.
You can also use the user settings API to assign a user to a specific variation for any feature flag.
