+# Roadmap for RT-Thread 1.2.0 #
+
+The document is the mainly task of RT-Thread 1.2.0. In this series, there will be a full manual document for RT-Thread 1.x series. The format of document is markdown document[0] on github.com and some hardware environment is used in document (RT-Thread Real-Touch[1]).
+
+The document will be wroten in Chinese firstly. At least when RT-Thread 1.2.0 has officially released, the Chinese edition of manual is ready. The manual includes:
+
+1. RT-Thread Kernel (The basic facilities in RTOS)
+2. How to port RT-Thread in a new architecture.
+3. RT-Thread components.
+4. How to debug in RT-Thread. 
+
+## Other codes changes in planning ##
+
+### Improvement on bsp porting ###
+
+- LPC18xx & LPC43xx
+  * USB host and device driver;
+
+- Other BSP.
+  * welcome contributions. 
+
+### New features on Components ###
+
+- device IPC
+  * implement the work queue[2].
+  * implement the rwlock[3].
+  * The APIs are like *BSD, but implement in RT-Thread
+
+- finsh shell
+  * implement a UNIX style shell, and this shell can execute application module. 
+
+- device file system
+  * implement select[4] API for device object in RT-Thread. 
+
+- lwIP TCP/IP stack
+  * enable IPv6 feature[5].
+
+- gdb server or stub
