+#### Vitrual elements
+
+The values for elements annotated with the annotation `@Core.Computed: true`, notably, virtual elements are no longer retained after CQN statement execution. Previously this was the case only for `Upsert` statement. Their values are no longer available in the `Result` of the CQN statement and are not available in the `@After` handlers.
