+## Changelog
+
+### 2.0.0
+
+- `@flow` and `@action` decorators removed. All simple functions
+(except `@view`'ed) will be considered as actions. All generators will become
+flow's. getters will become views. Use `@view` for parametrized views.
+- field with model type will not be automatically initialized with empty objects
+any more. So this code will throw error in new version:
+```js
+@model class Base {}
+
+@model class Container {
+  @Base base
+}
+```
+
+Use default value
+```js
+@model class Container {
+  @Base base = {}
+}
+```
+or `auto: true` option instead:
+```js
+@model({auto: true}) class Base {}
+
+@model class Container {
+  @Base base
+}
+```
+- basic typescript definitions
+
+### 1.0.0
