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.

+ 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.
