These are the features that Bram has partially implemented or planned for and were already in the todo list. These features are basic to any OOP language. Most of the changes are about fixing bugs, following the specification, making the behavior similar to the behavior in languages like Dart, Java and TypeScript and making the type checking strict. I think using a formal type checking term like "covariance" and "contra-variance" confuses people to think that we are introducing fancy features. But these are just terms for describing the type check and not new features. I could have used "implement appropriate type check for method arguments and return types in extended classes".
