 # use-effect-reducer
 
+## 0.6.0
+
+### Minor Changes
+
+- b1c53b2: Added support for initial effects, via the 2nd argument to `useEffectReducer`, which can either be a static `initialState` or a function that takes in `exec` and returns an initial state as well as executing initial effects:
+
+  ```js
+  const fetchReducer = (state, event) => {
+    if (event.type === 'RESOLVE') {
+      return {
+        ...state,
+        data: event.data,
+      };
+    }
+
+    return state;
+  };
+
+  const getInitialState = exec => {
+    exec({ type: 'fetchData', someQuery: '*' });
+
+    return { data: null };
+  };
+
+  // (in the component)
+  const [state, dispatch] = useEffectReducer(fetchReducer, getInitialState, {
+    fetchData(_, { someQuery }) {
+      fetch(`/some/api?${someQuery}`)
+        .then(res => res.json())
+        .then(data => {
+          dispatch({
+            type: 'RESOLVE',
+            data,
+          });
+        });
+    },
+  });
+  ```
