+Changes between FreeRTOS V10.4.4 and TBD
+
+	+ Introduce configRUN_TIME_COUNTER_TYPE which enables developers to define
+	  the type used to hold run time statistic counters. Defaults to uint32_t
+	  for backward compatibility. #define configRUN_TIME_COUNTER_TYPE to a type
+	  (for example, uint64_t) in FreeRTOSConfig.h to override the default.
+	+ Introduce ulTaskGetIdleRunTimePercent() to complement the pre-existing
+	  ulTaskGetIdleRunTimeCounter(). Whereas the pre-existing function returns
+	  the raw run time counter value, the new function returns the percentage of
+	  the entire run time consumed by the idle task. Note the amount of idle
+	  time is only a good measure of the slack time in a system if there are no
+	  other tasks executing at the idle priority, tickless idle is not used, and
