+Changes between FreeRTOS V10.4.0 and FreeRTOS V10.3.1 released September 1 2020
+
+ See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
+
+ Major enhancements:
+
+ + Task notifications: Prior to FreeRTOS V10.4.0 each created task had a
+ single direct to task notification. From FreeRTOS V10.4.0 each task has
+ an array of notifications. The direct to task notification API has been
+ extended with API functions postfixed with "Indexed" to enable the API to
+ operate on a task notification at any array index. See
+ https://www.freertos.org/RTOS-task-notifications.html for more information.
+ + Kernel ports that support memory protection units (MPUs): The ARMv7-M and
+ ARMv8-M MPU ports now support a privilege access only heap. The ARMv7-M
+ MPU ports now support devices that have 16 MPU regions, have the ability
+ to override default memory attributes for privileged code and data
+ regions, and have the ability to place the FreeRTOS kernel code outside of
+ the Flash memory. The ARMv8-M MPU ports now support tickless idle mode.
+ See https://www.freertos.org/FreeRTOS-MPU-memory-protection-unit.html
+ for more information.
+
+ Additional noteworthy updates:
+
+ + Code formatting is now automated to facilitate the increase in
+ collaborative development in Git. The auto-formated code is not identical
+ to the original formatting conventions. Most notably spaces are now used
+ in place of tabs.
+ + The prototypes for callback functions (those that start with "Application",
+ such as vApplicationStackOverflowHook()) are now in the FreeRTOS header
+ files, removing the need for application writers to add prototypes into
+ the C files in which they define the functions.
+ + New Renesas RXv3 port layer.
+ + Updates to the Synopsys ARC code, including support for EM and HS cores,
+ and updated BSP.
+ + Added new POSIX port layer that allows FreeRTOS to run on Linux hosts in
+ the same way the Windows port layer enables FreeRTOS to run on Windows
+ hosts.
+ + Many other minor optimisations and enhancements. For full details
+ see https://github.com/FreeRTOS/FreeRTOS-Kernel/commits/master
