 ## 开发日志
+  + v_3.3.11
+    - 添加进度更新间隔api，在`aria_config.xml`配置`<updateInterval value="1000"/>`或在代码中调用
+      `AriaManager.getInstance(AriaManager.APP).getDownloadConfig().setUpdateInterval(3000)`便可以改变进度刷新间隔
   + v_3.3.10
     - 修复地址切换导致下载失败的问题 https://github.com/AriaLyy/Aria/issues/181
     - 添加重置状态的api，当下载信息不改变，只是替换了服务器的对应的文件，可用`Aria.download(this).load(url).resetState()`重置下载状态 https://github.com/AriaLyy/Aria/issues/182
