The full log is at https://github.com/RTGUI/RTGUI/commits/merge_1 and it's difficult to merge the new tree commit by commit. I also converted all the file into unix eol so there are many fake diff. Big changes are noted in rtgui/doc/road_map.txt and rtgui/doc/attention.txt. Keep an eye on them if you want to migrate your old code. Note that the work is still in progress and the bsp is not prepared in trunk so far. git-svn-id: https://rt-thread.googlecode.com/svn/trunk@2092 bbd45198-f89e-11dd-88c7-29a3b14d5316
