+# 资源调度子系统ChangeLog
+
+## ohos.resourceschedule.runningLock.1  
+
+提醒代理支持系统应用设置自定义按钮，并且自定义按钮可申请RunningLock锁。
+
+**变更影响**
+
+基于OpenHarmony4.0.8.1及之后的SDK版本开发的系统应用，冻结后RunningLock锁释放，提高进入休眠概率。
+
+**关键接口/组件变更**
+
+| 模块名                | 类名         | 方法/属性/枚举/常量 | 变更类型 |
+| --------------------- | ------------ | ------------------- | -------- |
+| backgroundTaskManager | ResourceType | RUNNING_LOCK = 128  | 新增     |
+
+**适配指导**<br>
+
+```ts
+import runningLock from '@ohos.runningLock';
+
+let request = {
+    resourceTypes: backgroundTaskManager.ResourceType.RUNNING_LOCK,
+    isApply: true,
+    timeOut: 0,
+    reason: "apply",
+    isPersist: true
+};
+let res;
+try {
+    res = backgroundTaskManager.applyEfficiencyResources(request);//申请RUNNING_LOCK能效资源
+    console.info("the result of request is: " + res);
+} catch (error) {
+    console.error(`Operation applyEfficiencyResources failed. code is ${error.code} message is ${error.message}`);
+}
+
+runningLock.create('running_lock_test', runningLock.RunningLockType.BACKGROUND)
+    .then(lock => {
+    console.info('xuhanyang create running lock success');
+    try {
+        lock.hold(500000);//RUNNING_LOCK持锁500s
+        console.info('hold running lock success');
+    } catch(err) {
+        console.error('hold running lock failed, err: ' + err);
+    }
+})
+    .catch(err => {
+    console.error('create running lock failed, err: ' + err);
+});
+```
+
+## ohos.resourceschedule.sensor.2  
+
+冻结后Sensor处理，降低系统功耗。
+
+**变更影响**
+
+基于OpenHarmony4.0.8.1及之后的SDK版本开发的系统应用，可设置提醒自动消失。
+
+**关键接口/组件变更**
+
