| API Changes |
| *********** |
| |
| Changes in this release |
| ======================= |
| |
| * Zephyr now requires Python 3.8 or higher |
| |
| * Changed :c:struct:`spi_cs_control` to remove anonymous struct. |
| This causes possible breakage for static initialization of the |
| struct. Updated :c:macro:`SPI_CS_CONTROL_PTR_DT` to reflect |
| this change. |
| |
| * The :kconfig:option:`CONFIG_LEGACY_INCLUDE_PATH` option has been disabled by |
| default, all upstream code and modules have been converted to use |
| ``<zephyr/...>`` header paths. The option is still available to facilitate |
| the migration of external applications, but will be removed with the 3.4 |
| release. The :zephyr_file:`scripts/utils/migrate_includes.py` script is |
| provided to automate the migration. |
| |
| * :zephyr_file:`include/zephyr/zephyr.h` no longer defines ``__ZEPHYR__``. |
| This definition can be used by third-party code to compile code conditional |
| to Zephyr. The definition is already injected by the Zephyr build system. |
| Therefore, any third-party code integrated using the Zephyr build system will |
| require no changes. External build systems will need to inject the definition |
| by themselves, if they did not already. |
| |
| * :zephyr_file:`include/zephyr/zephyr.h` has been deprecated in favor of |
| :zephyr_file:`include/zephyr/kernel.h`, since it only included that header. No |
| changes are required by applications other than replacing ``#include |
| <zephyr/zephyr.h>`` with ``#include <zephyr/kernel.h>``. |
| |
| * CAN |
| |
| * The Zephyr SocketCAN definitions have been moved from :zephyr_file:`include/zephyr/drivers/can.h` |
| to :zephyr_file:`include/zephyr/net/socketcan.h`, the SocketCAN ``struct can_frame`` has been |
| renamed to :c:struct:`socketcan_frame`, and the SocketCAN ``struct can_filter`` has been renamed |
| to :c:struct:`socketcan_filter`. The SocketCAN utility functions are now available in |
| :zephyr_file:`include/zephyr/net/socketcan_utils.h`. |
| |
| * The CAN controller ``struct zcan_frame`` has been renamed to :c:struct:`can_frame`, and ``struct |
| zcan_filter`` has been renamed to :c:struct:`can_filter`. |
| |
| * The :c:enum:`can_state` enumerations have been renamed to contain the word STATE in order to make |
| their context more clear: |
| |
| * ``CAN_ERROR_ACTIVE`` renamed to :c:enumerator:`CAN_STATE_ERROR_ACTIVE`. |
| * ``CAN_ERROR_WARNING`` renamed to :c:enumerator:`CAN_STATE_ERROR_WARNING`. |
| * ``CAN_ERROR_PASSIVE`` renamed to :c:enumerator:`CAN_STATE_ERROR_PASSIVE`. |
| * ``CAN_BUS_OFF`` renamed to :c:enumerator:`CAN_STATE_BUS_OFF`. |
| |
| * The error code for :c:func:`can_send` when the CAN controller is in bus off state has been |
| changed from ``-ENETDOWN`` to ``-ENETUNREACH``. A return value of ``-ENETDOWN`` now indicates |
| that the CAN controller is in :c:enumerator:`CAN_STATE_STOPPED`. |
| |
| * The list of valid return values for the CAN timing calculation functions have been expanded to |
| allow distinguishing between an out of range bitrate/sample point, an unsupported bitrate, and a |
| resulting sample point outside the guard limit. |
| |
| * Memory Management Drivers |
| |
| * Added :c:func:`sys_mm_drv_update_page_flags` and |
| :c:func:`sys_mm_drv_update_region_flags` to update flags associated |
| with memory pages and regions. |
| |
| Removed APIs in this release |
| ============================ |
| |
| * The following functions, macros, and structures related to the |
| deprecated kernel work queue API have been removed: |
| |
| * ``k_work_pending()`` |
| * ``k_work_q_start()`` |
| * ``k_delayed_work`` |
| * ``k_delayed_work_init()`` |
| * ``k_delayed_work_submit_to_queue()`` |
| * ``k_delayed_work_submit()`` |
| * ``k_delayed_work_pending()`` |
| * ``k_delayed_work_cancel()`` |

| in favor of utilizing :c:macro:`DT_BUS` and variants. |
| |
| * STM32 LPTIM domain clock should now be configured using devicetree. |
| Related Kconfig :kconfig:option:`CONFIG_STM32_LPTIM_CLOCK` option is now |
| deprecated. |
| |
| * ``label`` property from devicetree as a base property. The property is still |
| valid for specific bindings to specify like :dtcompatible:`gpio-leds` and |
| :dtcompatible:`fixed-partitions`. |
| |
| * Bluetooth mesh Configuration Client API prefixed with ``bt_mesh_cfg_`` |
| is deprecated in favor of a new API with prefix ``bt_mesh_cfg_cli_``. |
| |
| * Pinmux API is now officially deprecated in favor of the pin control API. |

| ********************** |
| |
| * Console |
| |
| * C Library |
| |
| * Added Picolibc as a Zephyr module. Picolibc module is a footprint-optimized |
| full C standard library implementation that is configurable at the build |
| time. |
| * C library heap initialization call has been moved from the ``APPLICATION`` |
| phase to the ``POST_KERNEL`` phase to allow calling the libc dynamic memory |
| management functions (e.g. ``malloc()``) during the application |
| initialization phase. |
| * Added ``strerror()`` and ``strerror_r()`` functions to the minimal libc. |
| * Removed architecture-specific ``off_t`` type definition in the minimal |
| libc. ``off_t`` is now defined as ``intptr_t`` regardless of the selected |
| architecture. |
| |
| * C++ Subsystem |
| |
| * Added ``std::ptrdiff_t``, ``std::size_t``, ``std::max_align_t`` and |
| ``std::nullptr_t`` type definitions to the C++ subsystem ``cstddef`` |
| header. |
| * Renamed global constructor list symbols to prevent the native POSIX host |
| runtime from executing the constructors before Zephyr loads. |
| |
| * Emul |
| |
| * Filesystem |
| |
| * IPC |
| |
| * Management |
| |
| * MCUMGR race condition when using the task status function whereby if a |
| thread state changed it could give a falsely short process list has been |
| fixed. |
| * MCUMGR shell (group 9) CBOR structure has changed, the ``rc`` |
| response is now only used for mcumgr errors, shell command |
| execution result codes are instead returned in the ``ret`` |
| variable instead, see :ref:`mcumgr_smp_group_9` for updated |
| information. Legacy bahaviour can be restored by enabling |
| :kconfig:option:`CONFIG_MCUMGR_CMD_SHELL_MGMT_LEGACY_RC_RETURN_CODE` |
| * MCUMGR img_mgmt erase command now accepts an optional slot number |
| to select which image will be erased, using the ``slot`` input |
| (will default to slot 1 if not provided). |
| * MCUMGR :kconfig:option:`CONFIG_OS_MGMT_TASKSTAT_SIGNED_PRIORITY` is now |
| enabled by default, this makes thread priorities in the taskstat command |
| signed, which matches the signed priority of tasks in Zephyr, to revert |
| to previous behaviour of using unsigned values, disable this Kconfig. |
| * MCUMGR taskstat runtime field support has been added, if |
| :kconfig:option:`CONFIG_OS_MGMT_TASKSTAT` is enabled, which will report the |
| number of CPU cycles have been spent executing the thread. |
| * MCUMgr transport API drops ``zst`` parameter, of :c:struct:`zephyr_smp_transport` |
| type, from :c:func:`zephyr_smp_transport_out_fn` type callback as it has |
| not been used, and the ``nb`` parameter, of :c:struct:`net_buf` type, |
| can carry additional transport information when needed. |
| * A dummy SMP transport has been added which allows for testing MCUMGR |
| functionality and commands/responses. |
| * An issue with the UART/shell transports whereby large packets would wrongly |
| be split up with multiple start-of-frame headers instead of only one has been |
| fixed. |
| * SMP now runs in its own dedicated work queue which prevents issues running in |
| the system workqueue with some transports, e.g. Bluetooth, which previously |
| caused a deadlock if buffers could not be allocated. |
| * Bluetooth transport will now reduce the size of packets that are sent if they |
| are too large for the remote device instead of failing to send them, if the |
| remote device cannot accept a notification of 20 bytes then the attempt is |
| aborted. |
| * Unaligned memory access problems for CPUs that do not support it in MCUMGR |
| headers has been fixed. |
| * Groups in MCUMGR now use kernel slist entries rather than the custom MCUMGR |
| structs for storage. |
| * Levels of function redirection which were previously used to support multiple |
| OS's have been reduced to simplify code and reduce output size. |
| |
| * Cbprintf and logging |
| |
| * Updated cbprintf static packaging to interpret ``unsigned char *`` as a pointer |
| to a string. See :ref:`cbprintf_packaging_limitations` for more details about |
| how to efficienty use strings. Change mainly applies to the ``logging`` subsystem |
| since it uses this feature. |
| * Added :c:macro:`LOG_RAW` for logging strings without additional formatting. |
| It is similar to :c:macro:`LOG_PRINTK` but do not append ``<cr>`` when new line is found. |
| |
| * IPC |
| |
| * Introduced a 'zephyr,buffer-size' DT property to set the sizes for TX and |
| RX buffers per created instance. |
| * Set WQ priority back to PRIO_PREEMPT to fix an issue that was starving the scheduler. |
| * ``icmsg_buf`` library was renamed to ``spsc_pbuf``. |
| * Added cache handling support to ``spsc_pbuf``. |
| * Fixed an issue where the TX virtqueue was misaligned by 2 bytes due to the |
| way the virtqueue start address is calculated |
| * Added :c:func:`ipc_service_deregister_endpoint` function to deregister endpoints. |
| |
| * LoRaWAN |
| |
| * Modbus |
| |
| * Power management |
| |
| * POSIX |
| |
| * Make ``tz`` non-const in ``gettimeofday()`` for conformance to spec. |
| * Fix pthread descriptor resource leak. Previously only pthreads with state |
| ``PTHREAD_TERMINATED`` could be reused. However, ``pthread_join()`` sets |
| the state to ``PTHREAD_EXITED``. Consider both states as candidates in |
| ``pthread_create()``. |
| * Add ``perror()`` implementation |
| * Use consistent timebase in ``sem_timedwait()`` |
| |
| * RTIO |
| |
| * Initial version of an asynchronous task and executor API for I/O similar inspired |
| by Linux's very successful io_uring. |
| * Provides a simple linear and limited concurrency executor, simple task queuing, |
| and the ability to poll for task completions. |

| * SD Subsystem |
