2.0.0

[2.0.0] - 2023-04-13

The latest version of this SDK supports LaunchDarkly's new custom contexts feature. Contexts are an evolution of a previously-existing concept, "users." Contexts let you create targeting rules for feature flags based on a variety of different information, including attributes pertaining to users, organizations, devices, and more. You can even combine contexts to create "multi-contexts."

For detailed information about this version, please refer to the list below. For information on how to upgrade from the previous version, please read the migration guide.

Added:

• A new context type can be created by providing an associative array to the LaunchDarklyCreateContext function.
• A new reference type can be created by providing a string path to the LaunchDarklyCreateReference function.
• For all SDK methods that took a user parameter, you can now pass the new context type instead.

Removed:

• Removed the LaunchDarklyUser function and all supporting user related functionality.
• The alias method no longer exists because alias events are not needed in the new context model.
• The setInlineUsers and setAutoAliasingOptOut configuration functions no longer exists because they are not relevant in the new context model.
