+*** 2.4.1 ***
+- FIX: Fixed various minor documentation errors and fixed ADC maximum
+  frequency limit in STM32F2/F4 ADC drivers (bug 3484942).

 *** 2.4.0 ***
 - NEW: Implemented new makefile system for ARM GCC ports, now objects,
   listings and output files are generated into a "build" directory and not
