+### `0.2.1` :: multiple targets
+
+#### Multiple targets:
+
+```ruby
+defimpl MyProto, target: [MyClass1, MyClass2], delegate: [:add, :subtract]
+```
+
+### `0.2.0` :: implicit delegate on incomplete implementation
+
+when `defimpl` does not fully cover the protocol declaration,

+
+```ruby
+defimpl MyProto, target: MyClass, map: { add: :+, subtract: :- }
+#⇒ W, [2016-10-24T14:52:49.230808 #26382]  WARN -- : Implicit delegate MyProto#to_s to MyClass
