+## 0.2.4
+
+* Add: prototype chain functions:
+  * `forAllPrototypes.call(constructor, callback)` - calls callback(prototype) for all
+    prototypes in the prototype chain, including constructor.prototype
+  * `callPrototypeChainDown.call(instance, methodName,...args)` - calls methodName with args in
+    all prototypes in the chain which have the method in own properties with `this` set to
+    `instance`, calls are made in reverse prototype chain order
+  * `callPrototypeChainUp.call(instance, methodName,...args)` - calls methodName with args in
+    all prototypes in the chain which have the method in own properties with `this` set to
+    `instance`, calls are made in prototype chain order
