+## ProjectTo runtime polymorphic mapping with Include/IncludeBase
+
+We consider this an off the beaten path feature and we don't expose it through `CreateProjection`. You can use [an extension method](https://github.com/AutoMapper/AutoMapper/search?l=C%23&q=Advanced) or `CreateMap`.

+## `Context.State` similar to `Context.Items`
+
+The same pattern the framework uses to pass state to delegates. Note that `State` and `Items` are mutually exclusive per `Map` call.
+
+## Custom Equals/GetHashCode for source objects
+
+To avoid broken implementations, we no longer call those when checking for identical source objects, we hard code to checking object references.
