+Changes between FreeRTOS V10.4.0 and FreeRTOS V10.4.1 released September 17 2020
+	See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
+
+	+ Fixed an incorrectly named parameter that prevented the 
+	  ulTaskNotifyTakeIndexed macro compiling, and the name space clash in the 
+	  test code that prevented this error causing test failures.

+Changes between FreeRTOS V10.3.1 and FreeRTOS V10.4.0 released September 10 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

 ## Getting started
 This repository contains FreeRTOS kernel source/header files and kernel ports only. This repository is referenced as a submodule in [FreeRTOS/FreeRTOS](https://github.com/FreeRTOS/FreeRTOS) repository, which contains pre-configured demo application projects under ```FreeRTOS/Demo``` directory. 
 
-The easiest way to use FreeRTOS is to start with one of the pre-configured demo application projects.  That way you will have the correct FreeRTOS source files included, and the correct include paths configured.  Once a demo application is building and executing you can remove the demo application files, and start to add in your own application source files.  See the [FreeRTOS Kernel Quick Start Guide](https://www.freertos.org/FreeRTOS-quick-start-guide.html) for detailed instructions and other useful links.

+FreeRTOS files are formatted using the "uncrustify" tool. The configuration file used by uncrustify can be found in the [FreeRTOS/FreeRTOS repository](https://github.com/FreeRTOS/FreeRTOS/blob/master/tools/uncrustify.cfg).
