*** 2.3.4 ***
+- FIX: Fixed wrong macro definition in ARMv6-M architecture files (bug

- NEW: Now the STM32 SDC driver supports unaligned buffers transparently.
Optimized the driver for single block read and write operations.
+- NEW: Finished the reorganization of the Cortex-Mx ports, now also the
+ IAR and RVCT ports support the new Compact mode.
*** 2.3.3 ***
