CircleOS - Version 1.3 : 22.08.2007
- Optimized time display.
- The MEMS handler now launched from the TIMER2 interrupt handler instead of the systick interrupt.

- A hardware reset is now performed to reset the LCD monitor.

- Better filtering of the mems information
- Compiled with GCC version 4.2.1 (overall size is reduced)
CircleOS - Version 1.6 : 17.10.2007
- Place the vector table in RAM for per-user customization of IRQ Handlers
- Added functions to Get/Set IRQ Handlers
CircleOS - Version 1.7 : 08.11.2007

- Add DRAW_Line() function (draw a line using the Bresenham algorithm)
- Detect the doubleclick (stored in MEMS_Info that has been extended) and use it in the menu selection to launch a command
- Various fix in Circle_Api.h
