 - The root alias `@yii` now represents the framework installation directory.
    In 1.x, this is named as `system`. We also removed `zii` root alias.
 
+- Object serves as the base class that supports properties. And Component extends
+  from Object and supports events and behaviors. Behaviors declared in
+  Component::behaviors() are attached on demand.
 
 - `CList` is renamed to `Vector`, and `CMap` is renamed to `Dictionary`.
   Other collection classes are dropped in favor of SPL classes.
