:mega: kotlinx.serialization `0.11.0` has been released! This is an companion release to Kotlin 1.3.30. Some noticeable highlights:
• (Potentially breaking change) Semantics of serializable properties has been reworked. Now plugin considers property serializable only if it has backing field. Therefore, abstract, delegated and properties with custom getters/setters became automatically `@Transient`.
• `@Optional` is no longer required, properties with default values are automatically considered as optional.
• Polymorphic serialization is now available for JS and Native
• JSON received option to include class name in polymorphic serialization directly into json object instead of default `[className, object]` format.
