+Changes between FreeRTOS V10.2.1 and FreeRTOS V10.3.0 released February 7 2020
+
+	See http://www.FreeRTOS.org/FreeRTOS-V10.3.x.html
+
+	New and updated kernel ports:
+
+	+ Added RISC-V port for the IAR compiler.
+	+ Update the Windows simulator port to use a synchronous object to prevent
+	  a user reported error whereby a task continues to run for a short time
+	  after being moved to the Blocked state.  Note we were not able to
+	  replicate the reported issue and it likely depends on your CPU model.
+	+ Correct alignment of stack top in RISC-V port when
+	  configISR_STACK_SIZE_WORDS is defined to a non zero value, which causes
+	  the interrupt stack to be statically allocated.
+	+ The RISC-V machine timer compare register can now be for any HART, whereas
+	  previously it was always assumed FreeRTOS was running on HART 0.
+	+ Update the sequence used to update the 64-bit machine timer
+	  compare register on 32-bit cores to match that suggested in RISC-V
+	  documentation.
+	+ Added tickless low power modes into the ARM, IAR and GCC Cortex-M0 compiler
+	  ports.
+	+ Updated the behaviour of the ARMv7-M MPU (Memory Protection Unit) ports to
+	  match that of the ARMv8-M ports whereby privilege escalations can only
+	  originate from within the kernel's own memory segment.  Added
+	  configENFORCE_SYSTEM_CALLS_FROM_KERNEL_ONLY configuration constant.
+	+ Update existing MPU ports to correctly disable the MPU before it is
+	  updated.
+	+ Added contributed port and demo application for a T-Head (formally C-SKY)
+	  microcontroller.
+
+	New API functions:
+
+	+ Added the vPortGetHeapStats() API function which returns information on
+	  the heap_4 and heap_5 state.
+	+ Added xTaskCatchUpTicks(), which corrects the tick count value after the
+	  application code has held interrupts disabled for an extended period.
+	+ Added xTaskNotifyValueClear() API function.
+	+ Added uxTimerGetReloadMode() API function.
+
+	Other miscellaneous changes:
+	+ Change type of uxPendedTicks from UBaseType_t to TickType_t to ensure it
+	  has the same type as variables with which it is compared to, and therefore
+	  also renamed the variable xPendingTicks.
+	+ Update Keil projects that use the MPU so memory regions come from linker
+	  script (scatter file) variables instead of being hard coded.
+	+ Added LPC51U68 Cortex-M0+ demos for GCC (MCUXpresso), Keil and IAR
+	  compilers.
+	+ Added CORTEX_MPU_STM32L4_Discovery_Keil_STM32Cube demo.
+	+ Added LPC54018 MPU demo.
+	+ Rename xTaskGetIdleRunTimeCounter() to ulTaskGetIdleRunTimeCounter().
+
+
+Changes between FreeRTOS V10.2.1 and FreeRTOS V10.2.0 released May 13 2019:
+
+	+ Added ARM Cortex-M23 port layer to complement the pre-existing ARM
+	  Cortex-M33 port layer.
+	+ The RISC-V port now automatically switches between 32-bit and 64-bit
+	  cores.
+	+ Introduced the portMEMORY_BARRIER macro to prevent instruction re-ordering
+	  when GCC link time optimisation is used.
+	+ Introduced the portDONT_DISCARD macro to the ARMv8-M ports to try and
+	  prevent the secure side builds from removing symbols required by the
+	  non secure side build.
+	+ Introduced the portARCH_NAME to provide additional data to select semi-
+	  automated build environments.
+	+ Cortex-M33 and Cortex-M23 ports now correctly disable the MPU before
+	  updating the MPU registers.
+
+	+ Added Nuvoton NuMaker-PFM-M2351 ARM Cortex-M23 demo.
+	+ Added LPC55S69 ARM Cortex-M33 demo.
+	+ Added an STM32 dual core AMP stress test demo.
