+# formfwk子系统ChangeLog
+
+## cl.formfwk.1 @ohos.app.form.formHost.d.ts部分接口移出，接口权限变动
+
+1. @ohos.app.form.formHost.d.ts中涉及监听和获取卡片动态信息的接口移至@ohos.app.form.formObserver.d.ts;
+2. 涉及接口需申请权限由ohos.permission.REQUIRE_FORM修改为ohos.permission.OBSERVE_FORM_RUNNING。
+
+**变更影响**
+
+对于已发布的js接口，可能影响三方应用的兼容性。
+
+**关键的接口/组件变更**
+
+涉及接口移动、权限修改前的接口原型：
+
+|     接口      | 修改前所属d.ts | 修改后所属d.ts | 修改前所需权限 | 修改后所需权限 |

+
+
+**适配指导**
+
+已使用相关接口开发的应用工程，需要对接口进行适配。从OpenHarmony 4.0.9.5版本起，相关接口使用应导入@ohos.app.form.formObserver.d.ts，并申请ohos.permission.OBSERVE_FORM_RUNNING权限。
+
+**示例：**
+```js
+import formObserver from @ohos.app.form.formObserver.d.ts;
+
+try {
+  formObserver.getRunningFormInfos((error, data) => {
+    if (error) {
+      console.error(`error, code: ${error.code}, message: ${error.message}`);
+    } else {
+      console.log('formHost getRunningFormInfos, data: ${JSON.stringify(data)}');
+    }
+  }, 'com.example.ohos.formjsdemo');
+} catch(error) {
+  console.error(`catch error, code: ${error.code}, message: ${error.message}`);
+}
+```
