   - Abstract classes with `@Immutable` or `@Stable` annotations now correctly analyzed for stability
   - Sealed classes with `@Immutable`/`@Stable` now properly propagate stability to subclasses
   - Example: `@Immutable sealed class StableSealedClass` with `data class Stable(...)` subclass now correctly shows as STABLE instead of RUNTIME
-  - IDE plugin now matches compiler plugin behavior for sealed class hierarchies
+  - Both IDE plugin and compiler plugin now consistently handle sealed class hierarchies with stability annotations
