- NEW: Added board files for the Olimex STM32-P107.
- NEW: Improved setup packets handling in the USB driver through a specific
callback.
- NEW: Improvements to the PAL driver and various implementation in order
to make them more parenthesis friendly.
- OPT: Simplified Serial over USB driver configuration.
- CHANGE: Renamed the demo ARMCM3-STM32F107-GCC in ARMCM3-STM32F107 and added
IAR and Keil projects.
