- models get other models from DataStore (Relations) - documentation using Compodoc - rename and restructure - http-interceptor makes all http-objections obsolete - created 'Deserializable model' interface for better mapping of JSON objects - Supports multiple nested objects - No foreign dependancies, no magic - Simple yet efficient deserialize function - arrays of nested objects - created more classes for better OOP AOP
