 _2016-12-18_
 
 ### 核心:

+- 这个版本开始，我们不再默认依赖okhttp，你可以根据自己的需求进行定制。(如果你依然想要使用okhttp，可以考虑集成下这个[仓库](https://github.com/Jacksgong/filedownloader-okhttp3-connection))
 
 > 如果你依然需要配置`timeout`、`proxy`，请不用担心，我已经对默认的网络连接组件实现了这几个接口: [DemoApplication](https://github.com/lingochamp/FileDownloader/blob/master/demo/src/main/java/com/liulishuo/filedownloader/demo/DemoApplication.java#L35)，如果有需要可以看看。

 ## Version 1.3.9
 
 _2016-12-18_
 
 ### Important:

-- Since this version, FileDownloader don't dependency the okhttp as default.
+- Since this version, FileDownloader don't dependency the okhttp as default. (If you still want to use the okhttp as your connection component, you can integrate [this repo](https://github.com/Jacksgong/filedownloader-okhttp3-connection) feel free)
 
 > If you still need configure `timeout`、`proxy` for the connection component, but you don't want to implement your own one, don't worry, I implement it for the default connection component too, just move to : [DemoApplication](https://github.com/lingochamp/FileDownloader/blob/master/demo/src/main/java/com/liulishuo/filedownloader/demo/DemoApplication.java#L35), check the code if you want.
