2.0.0

[2.0.0] - 2022-12-01

This major version release of java-sdk-common corresponds to the upcoming v6.0.0 release of the LaunchDarkly Java SDK (java-server-sdk) and the v4.0.0 release of the LaunchDarkly Android SDK (android-client-sdk), and cannot be used with earlier SDK versions.

Added:

• The types LDContext and ContextKind define the new "context" model. "Contexts" are a replacement for the earlier concept of "users"; they can be populated with attributes in more or less the same way as before, but they also support new behaviors. More information about these features will be included in the release notes for the v6.0.0 Java SDK and v4.0.0 Android SDK releases.
• The type AttributeRef defines the attribute reference syntax, for referencing subproperties of JSON objects in flag evaluations or private attribute configuration. Applications normally will not need to reference this type.

Changed:

• It was previously allowable to set a user key to an empty string. In the new context model, the key is not allowed to be empty. Trying to use an empty key will cause evaluations to fail and return the default value.
• There is no longer such a thing as a secondary meta-attribute that affects percentage rollouts. If you set an attribute with that name in an LDContext, it will simply be a custom attribute like any other.
• The anonymous attribute in LDUser is now a simple boolean, with no distinction between a false state and a null state.

Removed:

• Removed all types, fields, and methods that were deprecated as of the most recent release.
• Removed the secondary meta-attribute in LDUser and LDUser.Builder.
