+## Components
+
+* When formatting the file system, adds FM_SFD option to create a volume in SFD format for FatFs; (HubretXie)

+* Fix stdio fd issue when POSIX api is used; (gbcwbz)
+* Fix the `fd_is_open()` issue: when the sub-path is the same in different mounted filesystem. 
+* Change the critical lock/unlock to dfs_lock/unlock in `getcwd()` function of DFS (the critical lock/unlock is different in SMP environment);

+
+# Tool
+
+* Provide more inforamtion when the tool chain does not exist;

 遵循2013年RT-Thread roadmap，RT-Thread 1.2.0 Alpha版本发布，Alpha意味着此版本为技术预览版，仅用于展示RT-Thread 1.2.0未来的发展方向，并不适合于开发正式产品。RT-Thread 1.2.0版本是1.1.x系列的下一个分支，这个分支主要体现的是RT-Thread 1.x系列的文档情况。当然也有一些功能、代码方面的增强。
 
 伴随着新版本的到来，RT-Thread有几个重大的转变：
