+	    the application or not. The MSB of the size field is used for this
+	    purpose. The same check already exists in heap_4 and heap_5. This
+	    check prevents double free errors.
+	  - Add a new flag configHEAP_CLEAR_MEMORY_ON_FREE to heap_2, heap_4
+	    and heap_5. If the flag is set in FreeRTOSConfig.h then memory freed using
+	    vPortFree() is automatically cleared to zero.
+	  - Add a new API pvPortCalloc to heap_2, heap_4 and heap_5 which has the same
+	    signature as the standard library calloc function.
+	+ Add the ability to override send and receive completed callbacks for each
+	  instance of a stream buffer or message buffer. Earlier there could be
+	  one send and one receive callback for all instances of stream and message
+	  buffers. Having separate callbacks per instance allows different message
+	  and stream buffers to be used differently - for example, some for inter core
+	  communication and others for same core communication.
+	  The feature can be controlled by setting  the configuration option
+	  configUSE_SB_COMPLETED_CALLBACK in FreeRTOSConfig.h. When the option is set to 1,
+	  APIs xStreamBufferCreateWithCallback() or xStreamBufferCreateStaticWithCallback()
+	  (and likewise APIs for message buffer) can be used to create a stream buffer 
+	  or message buffer instance with application provided callback overrides. When
+	  the option is set to 0, then the default callbacks as defined by
+	  sbSEND_COMPLETED() and sbRECEIVE_COMPLETED() macros are invoked. To maintain 
+	  backwards compatibility, configUSE_SB_COMPLETED_CALLBACK defaults to 0. The 
+	  functionality is currently not supported for MPU enabled ports.
+	+ Add support to build and link FreeRTOS using CMake build system. Contributed
+	  by @yhsb2k.
+	+ Add support to generate Software Bill of Materials (SBOM) for every release.
+	+ Add support for 16 MPU regions to the GCC Cortex-M33 ports.
+	+ Add ARM Cortex-M7 r0p0/r0p1 Errata 837070 workaround to ARM CM4 MPU ports.
+	  The application writer needs to define configENABLE_ERRATA_837070_WORKAROUND
+	  when using CM4 MPU ports on a Cortex-M7 r0p0/r0p1 core.
+	+ Add configSYSTICK_CLOCK_HZ to Cortex-M0 ports. This is needed to support
+	  the case when the SysTick timer is not clocked from the same source as the CPU.
+	+ Add hardware stack protection support to MicroBlazeV9 port. This ensures that
+	  the CPU immediately raises Stack Protection Violation exception as soon as any
+	  task violates its stack limits. Contributed by @uecasm.
 	+ Introduce the configUSE_MINI_LIST_ITEM configuration option. When this
 	  option is set to 1, ListItem_t and MiniLitItem_t remain separate types.
 	  However, when configUSE_MINI_LIST_ITEM == 0, MiniLitItem_t and ListItem_t
 	  are both typedefs of the same struct xLIST_ITEM. This addresses some issues
 	  observed when strict-aliasing and link time optimization are enabled.
 	  To maintain backwards compatibility, configUSE_MINI_LIST_ITEM defaults to 1.

+	  cRxLock and cTxLock to the number of tasks in the system because we cannot
+	  unblock more tasks than there are in the system. Note that the same assert
+	  could still be triggered is the application creates more than 127 tasks.
+	+ Changed uxAutoReload parameter in timer functions to xAutoReload.  The
+	  type is now BaseType_t.  This matches the type of pdTRUE and pdFALSE.
+	  The new function xTimerGetAutoReload() provides the auto-reload state as
+	  a BaseType_t.  The legacy function uxTimerGetAutoReload is retained with the
+	  original UBaseType_t return value.
+	+ Fix support for user implementations of tickless idle that call
+	  vTaskStepTick() with xExpectedIdleTime ticks to step. The new code
+	  ensures xTickCount reaches xNextTaskUnblockTime inside xTaskIncrementTick()
+	  instead of inside vTaskStepTick(). This fixes the typical case where a task
+	  wakes up one tick late and a rare case assertion failure when xTickCount\
+	  rolls over. Contributed by @jefftenney.
+	+ Fix deadlock in event groups when pvPortMalloc and vPortFree functions
+	  are protected with a mutex. Contributed by @clemenskresser.
+	+ Fix a warning in tasks.c when compiled with -Wduplicated-branches
+	  GCC option. Contributed by @pierrenoel-bouteville-act.
+	+ Fix compilation error in tasks.c when configSUPPORT_DYNAMIC_ALLOCATION
+	  is set to zero. Contributed by @rdpoor.
+	+ Fix prvWriteMessageToBuffer() function in stream_buffer.c so that it correctly
+	  copies length on big endian platforms too.
+	+ Remove the need for  INCLUDE_vTaskSuspend to be set to 1
+	  when configUSE_TICKLESS_IDLE is enabled. Contributed by @pramithkv.
+	+ Update the RL78 IAR port to the latest version of IAR which uses the
+	  industry standard ELF format as opposed to earlier UBROF object format.
+	  Contributed by @felipe-iar.
+	+ Add tick type is atomic flag when tick count is 16-bit to PIC24 port. This
+	  allows the PIC24 family of 16 bit processors to read the tick count without
+	  a critical section when the tick count is also 16 bits.
+	+ Fix offset-out-of-range errors for GCC CM3/CM4 mpu ports when
+	  Link Time Optimization is enabled. Contributed by @niniemann.
+	+ Remove #error when RISC-V port is compiled on a 64-bit RISC-V platform.
+	  Contributed by @cmdrf.
+	+ Fix ullPortInterruptNesting alignment in Cortex-A53 port so that it is
+	  8-byte aligned. This fixes the unaligned access exception. Contributed
+	  by @Atomar25.
+	+ Fix  Interrupt Handler Register Function and Exception Process in NiosII
+	  Port. Contributed by @ghost.
+	+ Change FreeRTOS IRQ Handler for Cortex-A53 SRE port to store and restore
+	  interrupt acknowledge register. This ensures that the SRE port behavior
+	  matches the Memory Mapped IO port. Contributed by @sviaunxp.
+	+ Update the uncrustify config file to match the version of the uncrustify
+	  used in the CI Action. Also, pin the version of uncrustify in CI. Contributed
+	  by @swaldhoer.
