*** 2.1.2 ***
+- FIX: Fixed broken CH_DBG_ENABLE_STACK_CHECK option in legacy CM3 port (bug
+ 3064274)(backported to 2.0.5).
- FIX: Fixed CAN_USE_SLEEP_MODE setting (bug 3064204)(backported to 2.0.5).
- FIX: Fixed potential issue with GCC reorganizing instructions around "asm
volatile" statements (bug 3058731)(backported in 2.0.4).

- NEW: Added board files for the Olimex STM32-H103.
- NEW: New kernel APIs chSysGetIdleThread() and chThdGetTicks(), the new
APIs are simple macros so there is no footprint overhead.
-- NEW: New I2C device driver model (no implementations yet).
+- NEW: New I2C device driver model (not complete and no implementations yet).
- NEW: Added to the UART driver the capability to return the number of
not yet transferred frames when stopping an operation.
- NEW: Added more compile-time checks to the various STM32 device drivers.
