   those are not functions but inlined code. Also introduced a new macro
   CH_IRQ_HANDLER that should be used when declaring an interrupt handler.
+  CHANGE: Renamed several internal initialization functions by removing the

 - Improved ARM7 and Cortex-M3 support, new configuration options.
 - Introduced the concept of interrupt classes, see the documentation.
 - Introduced the concept of system states, see the documentation.
