+## cl.window.1 WindowStage生命周期监听类型名称变更
+
+WindowStage生命周期的监听类型枚举定义自4.0.1.1版本起进行了变更。
+
+**变更影响**
+
+4.0.1.1版本之前使用FOREGROUND/BACKGROUND类型开发的应用生命周期监听，在4.0.1.1版本之后失效。
+
+**关键接口/组件变更**
+
+##  WindowStageEventType<sup>9+</sup>
+
+变更前：
+
+| 名称       | 值   | 说明       |
+| ---------- | ---- | ---------- |
+| FOREGROUND | 1    | 切到前台。 |
+| BACKGROUND | 4    | 切到后台。 |
+
+变更后：
+| 名称   | 值   | 说明       |
+| ------ | ---- | ---------- |
+| SHOWN  | 1    | 切到前台。 |
+| HIDDEN | 4    | 切到后台。 |
+
+**适配指导**
+
+在注册生命周期监听回调时，将前后台事件类型改为SHOWN/HIDDEN：
+
+```
+import Ability from '@ohos.application.Ability';
+
+class myAbility extends Ability {
+    onWindowStageCreate(windowStage) {
+        console.log('onWindowStageCreate');
+        try {
+            windowStage.on('windowStageEvent', (stageEventType) => {
+                switch (stageEventType) {
+                    case window.WindowStageEventType.SHOWN:
+                        console.log("windowStage shown");
+                        break;
+                    case window.WindowStageEventType.ACTIVE:
+                        console.log("windowStage active");
+                        break;
+                    case window.WindowStageEventType.INACTIVE:
+                        console.log("windowStage inActive");
+                        break;
+                    case window.WindowStageEventType.HIDDEN:
+                        console.log("windowStage hidden");
+                        break;
+                    default:
+                        break;
+                }
+        	} )
+        } catch (exception) {
+            console.error('Failed to enable the listener for window stage event changes. Cause:' +
+                JSON.stringify(exception));
+        };
+    }
+};
+```
