+## Enum Compatibility

+The API may return enum values added after this SDK version was generated. In those cases, JSON deserialization maps those values to the generated `UNKNOWN` enum member instead of failing. Use the generated `IsValid()` and `New...FromValue()` helpers when you need to check whether a value is part of the SDK's known enum set.
