* CVE-2023-0779: Under embargo until 2023-04-22
API Changes
***********
* Emulator creation APIs have changed to better match
:c:macro:`DEVICE_DT_DEFINE`. It also includes a new backend API pointer to
allow sensors to share common APIs for more generic tests.
Changes in this release
=======================
* Newlib nano variant is no longer selected by default when
:kconfig:option:`CONFIG_NEWLIB_LIBC` is selected.
:kconfig:option:`CONFIG_NEWLIB_LIBC_NANO` must now be explicitly selected in
order to use the nano variant.
* Bluetooth: Added extra options to bt_le_per_adv_sync_transfer_subscribe to
allow disabling sync reports, and enable sync report filtering. these two
options are mutually exclusive.
* Bluetooth: :kconfig:option:`CONFIG_BT_PER_ADV_SYNC_TRANSFER_RECEIVER`
and :kconfig:option:`CONFIG_BT_PER_ADV_SYNC_TRANSFER_SENDER` have been
added to enable the PAST implementation rather than
:kconfig:option:`CONFIG_BT_CONN`.
* Flashdisk: :kconfig:option:`CONFIG_DISK_FLASH_VOLUME_NAME`,
:kconfig:option:`CONFIG_DISK_FLASH_DEV_NAME`,
:kconfig:option:`CONFIG_DISK_FLASH_START`,
:kconfig:option:`CONFIG_DISK_FLASH_MAX_RW_SIZE`,
:kconfig:option:`CONFIG_DISK_ERASE_BLOCK_SIZE`,
:kconfig:option:`CONFIG_DISK_FLASH_ERASE_ALIGNMENT`,
:kconfig:option:`CONFIG_DISK_VOLUME_SIZE` and
:kconfig:option:`CONFIG_DISK_FLASH_SECTOR_SIZE` Kconfig options have been
removed in favor of new :dtcompatible:`zephyr,flash-disk` devicetree binding.
* Regulator APIs previously located in ``<zephyr/drivers/regulator/consumer.h>``
are now part of ``<zephyr/drivers/regulator.h>``.
* Starting from this release ``zephyr-`` prefixed tags won't be created
anymore. The project will continue using ``v`` tags, for example ``v3.3.0``.
* Bluetooth: Deprecated the Bluetooth logging subsystem in favor of the Zephyr
standard logging system. To enable debugging for a particular module in the
Bluetooth subsystem, enable `CONFIG_BT_(module name)_LOG_LEVEL_DBG` instead of
`CONFIG_BT_DEBUG_(module name)`.
* MCUmgr img_mgmt now requires that a full sha256 hash to be used when
uploading an image to keep track of the progress, where the sha256 hash
is of the whole file being uploaded (different to the hash used when getting
image states). Use of a truncated hash or non-sha256 hash will still work
but will cause issues and failures in client software with future updates
to Zephyr/MCUmgr such as image verification.
* MCUmgr handlers no longer need to be registered by the application code,
handlers just need to use a define which will then call the supplied
registration function at boot-up. If applications register this then
those registrations should be removed to prevent registering the same
handler multiple times.
* MCUmgr Bluetooth and UDP transports no longer need to be registered by the
application code, these will now automatically be registered at boot-up (this
feature can be disabled for the UDP transport by setting
:kconfig:option:`CONFIG_MCUMGR_TRANSPORT_UDP_AUTOMATIC_INIT`). If
applications register transports then those registrations should be removed
to prevent registering the same transport multiple times.
* MCUmgr transport Kconfigs have changed from ``select`` to ``depends on``
which means that for applications using the Bluetooth transport,
applications will now need to enable the following:
* :kconfig:option:`CONFIG_BT`
* :kconfig:option:`CONFIG_BT_PERIPHERAL`
For CDC or serial transports:
* :kconfig:option:`CONFIG_CONSOLE`
For shell transport:
* :kconfig:option:`CONFIG_SHELL`
* :kconfig:option:`CONFIG_SHELL_BACKEND_SERIAL`
For UDP transport:
* :kconfig:option:`CONFIG_NETWORKING`
* :kconfig:option:`CONFIG_NET_UDP`
* MCUmgr fs_mgmt hash/checksum function, type and variable names have been
changed to be prefixed with ``fs_mgmt_`` to retain alignment with other
zephyr and MCUmgr APIs.
* Python's argparse argument parser usage in Zephyr scripts has been updated
to disable abbreviations, any future python scripts or python code updates
must also disable allowing abbreviations by using ``allow_abbrev=False``
when setting up ``ArgumentParser()``.
This may cause out-of-tree scripts or commands to fail if they have relied
upon their behaviour previously, these will need to be updated in order for
building to work. As an example, if a script argument had ``--reset-type``
and an out-of-tree script used this by passing ``--reset`` then it will need
to be updated to use the full argument name, ``--reset-type``.
* Rewrote the CAN API to utilize flag bitfields instead discrete of struct
members for indicating standard/extended CAN ID, Remote Transmission Request
(RTR), and added support for filtering of CAN-FD format frames.
* New :ref:`Zephyr message bus (Zbus) <zbus>` subsystem added; a message-oriented
bus that enables one-to-one, one-to-many and many-to-many communication
between threads.
* zTest now supports controlling test summary printouts via the
:kconfig:option:`CONFIG_ZTEST_SUMMARY`. This Kconfig can be set to ``n`` for
less verbose test output.
* Emulators now support a backend API pointer which allows a single class of
devices to provide similar emulated functionality. This can be used to write
a single test for the class of devices and testing various boards using
different chips.
Removed APIs in this release
============================
* Removed :kconfig:option:`CONFIG_COUNTER_RTC_STM32_LSE_DRIVE*`
This should now be configured using the ``driving_capability`` property of
LSE clock
* Removed :kconfig:option:`CONFIG_COUNTER_RTC_STM32_LSE_BYPASS`
This should now be configured using the new ``lse_bypass`` property of
LSE clock
* Removed :kconfig:option:`CONFIG_COUNTER_RTC_STM32_BACKUP_DOMAIN_RESET`. Its purpose
was to control the reset of the counter value at board reset. It is removed since
it has too wide scope (full Backup RAM reset). Replaced by
:kconfig:option:`CONFIG_COUNTER_RTC_STM32_SAVE_VALUE_BETWEEN_RESETS` which also
allows to control the reset of counter value, with an opposite logic.
* Removed deprecated tinycbor module, code that uses this module should be
updated to use zcbor as a replacement.
* Removed deprecated GPIO flags used for setting debounce, drive strength and
voltage level. All drivers now use vendor-specific flags as needed.
* Removed deprecated ``UTIL_LISTIFY`` helper macro.
* Removed deprecated ``pwm_pin*`` family of functions from the PWM API.
* Removed deprecated ``nvs_init`` function from the NVS filesystem API.
* Removed deprecated ``DT_CHOSEN_*_LABEL`` helper macros.
* Removed deprecated property ``enable-pin-remap`` from :dtcompatible: `st,stm32-usb`:.
``remap-pa11-pa12`` from :dtcompatible: `st-stm32-pinctrl`: should now be used.
Deprecated in this release
==========================
* :ref:`xtools toolchain variant <toolchain_xtools>` is now deprecated. When using a
custom toolchain built with Crosstool-NG, the
:ref:`cross-compile toolchain variant <other_x_compilers>` should be used instead.
* C++ library Kconfig options have been renamed to improve consistency. See
below for the list of deprecated Kconfig options and their replacements:
.. table::
:align: center
+----------------------------------------+------------------------------------------------+
| Deprecated | Replacement |

+----------------------------------------+------------------------------------------------+
| :kconfig:option:`CONFIG_LIB_CPLUSPLUS` | :kconfig:option:`CONFIG_LIBCPP_IMPLEMENTATION` |
+----------------------------------------+------------------------------------------------+
* MCUmgr subsystem, specifically the SMP transport API, is dropping `zephyr_`
prefix, deprecating prefixed functions and callback type definitions with the
prefix and replacing them with with prefix-less variants.
The :c:struct:`zephyr_smp_transport` type, representing transport object,
is now replaced with :c:struct:`smp_transport`, and the later one is used,
instead of the former one, by all prefix-less functions.

* STM32 Ethernet Mac address Kconfig related symbols (:kconfig:option:`CONFIG_ETH_STM32_HAL_RANDOM_MAC`,
:kconfig:option:`CONFIG_ETH_STM32_HAL_MAC4`, ...) have been deprecated in favor
of the use of zephyr generic device tree ``local-mac-address`` and ``zephyr,random-mac-address``
properties.
* STM32 RTC source clock should now be configured using devicetree.
Related Kconfig :kconfig:option:`CONFIG_COUNTER_RTC_STM32_CLOCK_LSI` and
:kconfig:option:`CONFIG_COUNTER_RTC_STM32_CLOCK_LSE` options are now
deprecated.
* STM32 Interrupt controller Kconfig symbols such as :kconfig:option:`CONFIG_EXTI_STM32_EXTI0_IRQ_PRI`
are removed. Related IRQ priorities should now be configured in device tree.
* `PWM_STM32_COMPLEMENTARY` deprecated in favor of `STM32_PWM_COMPLEMENTARY`.

:kconfig:option:`CONFIG_SETTINGS_FS` in favor of :kconfig:option:`CONFIG_SETTINGS_FILE`
:kconfig:option:`CONFIG_SETTINGS_FS_DIR` in favor of creating all parent
directories from :kconfig:option:`CONFIG_SETTINGS_FILE_PATH`
:kconfig:option:`CONFIG_SETTINGS_FS_FILE` in favor of :kconfig:option:`CONFIG_SETTINGS_FILE_PATH`

deprecated in favor of a centralized scan of available PCIe devices.
* POSIX API
* Deprecated :c:macro:`PTHREAD_COND_DEFINE`, :c:macro:`PTHREAD_MUTEX_DEFINE` in favour of the
standard :c:macro:`PTHREAD_COND_INITIALIZER` and :c:macro:`PTHREAD_MUTEX_INITIALIZER`.

Stable API changes in this release
==================================
* MCUmgr events have been reworked to use a single, unified callback system.
This allows better customisation of the callbacks with a lower flash size.
Applications using the existing callback system will need to be upgraded to
use the new API by following the :ref:`migration guide <mcumgr_cb_migration>`
* :c:func:`net_pkt_get_frag`, :c:func:`net_pkt_get_reserve_tx_data` and
:c:func:`net_pkt_get_reserve_rx_data` functions are now requiring to specify
the minimum fragment length to allocate, so that they work correctly also in
case :kconfig:option:`CONFIG_NET_BUF_VARIABLE_DATA_SIZE` is enabled.
Applications using this APIs will need to be updated to provide the expected
fragment length.
* Marked the Controller Area Network (CAN) controller driver API as stable.

* NXP EDMA Unused mutex removed
* EEPROM
* Added fake EEPROM driver for testing purposes.
* Ethernet
* STM32: Default Mac address configuration is now uid based. Optionally, user can
configure it to be random or provide its own address using device tree.

:kconfig:option:`CONFIG_ETH_STM32_MULTICAST_FILTER`.
* STM32: Now supports statistics logging through :kconfig:option:`CONFIG_NET_STATISTICS_ETHERNET`.
Requires use of HAL Ethernet API V2.
* Flash
* Flash: Moved CONFIG_FLASH_FLEXSPI_XIP into the SOC level due to the flexspi clock initialization occurring in the SOC level.
* NRF: Added CONFIG_SOC_FLASH_NRF_TIMEOUT_MULTIPLIER to allow tweaking the timeout of flash operations.
* spi_nor: Added property mxicy,mx25r-power-mode to jedec,spi-nor binding for controlling low power/high performance mode on Macronix MX25R* Ultra Low Power flash devices.
* spi_nor: Added check if the flash is busy during init. This used to cause
the flash device to be unavailable until the system was restarted. The fix
waits for the flash to become ready before continuing. In cases where a
full flash erase was started before a restart, this might result in several
minutes of waiting time (depending on flash size and erase speed).
* rpi_pico: Added a flash driver for the Raspberry Pi Pico platform.
* STM32 OSPI: sfdp-bfp table and jedec-id can now be read from device tree and override
the flash content if required.

:kconfig:option:`CONFIG_PM_DEVICE`, :kconfig:option:`CONFIG_PM_DEVICE_RUNTIME`.
* STM32: Domain clock can now be configured using device tree
* I3C
* Added a new target device API :c:func:`i3c_target_tx_write` to
explicit write to TX FIFO.
* GETMRL and GETMWL are both optional in :c:func:`i3c_device_basic_info_get` as
MRL and MWL are optional according to I3C specification.
* Added a new driver to support Cadence I3C controller.
* Interrupt Controller
* STM32: Driver configuration and initialization is now based on device tree

resulting in infinite TXF interrupts.
* MBOX
* Added NXP S32 Message Receive Unit (MRU) driver.
* PCIE
* Support for accessing I/O BARs, which was previously removed, is back.
* Added new API :c:func:`pcie_scan` to scan for devices.
* This iterates through the the buses and devices which are expected to
exist. The old method was to try all possible combination of buses
and devices to determine if there is a device there.
:c:func:`pci_init` and :c:func:`pcie_bdf_lookup` have been updated to
use this new API.
* :c:func:`pcie_scan` also introduces a callback mechanism for when
a new device has been discovered.
* Pin control
* Common pin control properties are now defined at root level in a single
file: :zephyr_file:`dts/bindings/pinctrl/pincfg-node.yaml`. Pin control
bindings are expected to include it at the level they need. For example,
drivers using the grouping representation approach need to include it at
grandchild level, while drivers using the node approach need to include it
at the child level. This change will only impact out-of-tree pin control
drivers, since all in-tree drivers have been updated.
* Added NXP S32 SIUL2 driver
* Added Nuvoton NuMicro driver

* Added driver for NXP PCA9685 LED controller
* Regulators
* Completed an API overhaul so that devices like PMICs can be supported. The
API now offers a clear and concise API that allows to perform the following
operations:
- Enable/disable regulator output (reference counted)
- List supported voltages
- Get/set operating voltage
- Get/set maximum current
- Get/set operating mode
- Obtain errors, e.g. overcurrent.
The devicetree part maintains compatibility with Linux bindings, for example,
the following properties are well supported:
- ``regulator-boot-on``
- ``regulator-always-on``
- ``regulator-min-microvolt``
- ``regulator-max-microvolt``
- ``regulator-min-microamp``
- ``regulator-max-microamp``
- ``regulator-allowed-modes``
- ``regulator-initial-mode``
A common driver class layer takes care of the common functionality so that
driver implementations are kept simple. For example, allowed voltage ranges
are verified before calling into the driver.
An experimental parent API to configure DVS (Dynamic Voltage Scaling) has
also been introduced.
* Refactored NXP PCA9420 driver to align with the new API.
* Added support for nPM6001 PMIC (LDO and BUCK converters).

* Added a new test that allows to verify regulator output voltage using the
ADC API.
* Added a new test that checks API behavior provided we have a well-behaved
driver.
* Reset
* STM32: STM32 reset driver is now available. Devices reset line configuration should
be done using device tree.
* SDHC
* i.MX RT USDHC:
- Support HS400 and HS200 mode. This mode is used with eMMC devices,
and will enable high speed operation for those cards.
- Support DMA operation on SOCs that do not support non-cacheable memory,
such as the RT595. DMA will enable higher performance SD modes,
such as HS400 and SDR104, to reliably transfer data using the
SD host controller
* Sensor
* Refactored all drivers to use :c:macro:`SENSOR_DEVICE_DT_INST_DEFINE` to
enable a new sensor info iterable section and shell command. See
:kconfig:option:`CONFIG_SENSOR_INFO`.

existence of a timer device in kconfig
* Significant rework to nrf_rtc_timer with multiple fixes
* Fixed prescaler correction in stm32_lptim driver and fix race with auto-reload
* USB
* STM32F1: Clock bus configuration is not done automatically by driver anymore.
It is user's responsibility to configure the proper bus prescaler using clock_control
device tree node to achieve a 48MHz bus clock. Note that, in most cases, core clock
is 72MHz and default prescaler configuration is set to achieve 48MHz USB bus clock.
Prescaler only needs to be configured manually when core clock is already 48MHz.
* STM32 (non F1): Clock bus configuration is now expected to be done in device tree
using ``clocks`` node property. When a dedicated HSI 48MHz clock is available on target,
is it configured by default as the USB bus clock, but user has the ability to select
another 48MHz clock source. When no HSI48 is available, a specific 48MHz bus clock
source should be configured by user.
* STM32: Now supports :c:func:`usb_dc_detach` and :c:func:`usb_dc_wakeup_request`.
* STM32: Vbus sensing is now supported and determined based on the presence of the
hardware detection pin(s) in the device tree. E.g: pinctrl-0 = <&usb_otg_fs_vbus_pa9 ...>;
* RPi Pico: fixed buffer status handling, fixed infinite unhandled irq retriggers,
fixed DATA PID toggle and control transfer handling.
* NXP: Enabled high speed support, fixed endpoint buffer write operation.
* nRF USBD: Removed HAL driver uninit on detach, fixed endpoints disable on
USB stack disable.
* Added new experimental USB device controller (UDC) API and implementation
for nRF USBD, Kinetis USBFSOTG, and virtual controllers.
* Added new experimental USB host controller (UDC) API and implementation
for MAX3421E and virtual controllers.
* Watchdog
* Added driver for nPM6001 PMIC Watchdog.
* Added free watchdog driver for GigaDevice GD32 SoCs.
* Added window watchdog driver for GigaDevice GD32 SoCs.
* Added NXP S32 Software Watchdog Timer driver.

Modified bindings:
- Generic or vendor-independent:
- All sensor devices now have a ``friendly-name`` property,
which is a human-readable string describing the sensor.
See :zephyr_file:`dts/bindings/sensor/sensor-device.yaml`
for more information.
- All DMA controller devices have had their ``dma-buf-alignment``
properties renamed to ``dma-buf-addr-alignment``.
Additionally, all DMA controller devices have new
``dma-buf-size-alignment`` and ``dma-copy-alignment`` properties.
See :zephyr_file:`dts/bindings/dma/dma-controller.yaml` for
more information.

=====
Shields
* In order to avoid name conflicts with devices that may be defined at
board level, it is advised, specifically for shields devicetree descriptions,
to provide a device nodelabel in the form ``<device>_<shield>``. In-tree shields
have been updated to follow this recommendation.
* Others
* STM32F1 SoCs
* Added new pinctrl definitions for STM32F1xx PWM input. In PWM capture mode
STM32F1xx pins have to be configured as input and not as alternate.
The new names takes the form tim1_ch1_pwm_in_pa8 for example.
* Renamed pinctrl definitions for STM32F1xx PWM output to differentiate them
from newly created inputs. The new names takes the form tim1_ch1_pwm_out_pa8
instead of tim1_ch1_pwm_pa8.
Libraries / Subsystems
**********************
* C Library
* Newlib nano variant is no longer selected by default when
:kconfig:option:`CONFIG_NEWLIB_LIBC` is selected.
:kconfig:option:`CONFIG_NEWLIB_LIBC_NANO` must now be explicitly selected
in order to use the nano variant.
* Picolibc now supports all architectures supported by Zephyr.
* Added C11 ``aligned_alloc`` support to the minimal libc.
* C++ Library
* C++ support in Zephyr is no longer considered a "subsystem" because it
mainly consists of the C++ ABI runtime library and the C++ standard
library, which are "libraries" that are dissimilar to the existing Zephyr
subsystems. C++ support components are now located in ``lib/cpp`` as
"C++ library."
* C++ ABI runtime library components such as global constructor/destructor
and initialiser handlers, that were previously located under
``subsys/cpp``, have been moved to ``lib/cpp/abi`` in order to provide a
clear separation between the C++ ABI runtime library and the C++ standard
library.
* C++ minimal library components have been moved to ``lib/cpp/minimal``.
* C++ tests have been moved to ``tests/lib/cpp``.
* C++ samples have been moved to ``samples/cpp``.
* :kconfig:option:`CONFIG_CPLUSPLUS` has been renamed to
:kconfig:option:`CONFIG_CPP`.
* :kconfig:option:`CONFIG_EXCEPTIONS` has been renamed to
:kconfig:option:`CONFIG_CPP_EXCEPTIONS`.
* :kconfig:option:`CONFIG_RTTI` has been renamed to
:kconfig:option:`CONFIG_CPP_RTTI`.
* :kconfig:option:`CONFIG_LIB_CPLUSPLUS` is deprecated. A toolchain-specific
C++ standard library Kconfig option from
:kconfig:option:`CONFIG_LIBCPP_IMPLEMENTATION` should be selected instead.
* Zephyr subsystems and modules that require the features from the full C++
standard library (e.g. Standard Template Library) can now select
:kconfig:option:`CONFIG_REQUIRES_FULL_LIBC`, which automatically selects
a compatible C++ standard library.
* Introduced :kconfig:option:`CONFIG_CPP_MAIN` to support defining ``main()``
function in a C++ source file. Enabling this option makes the Zephyr kernel
invoke ``int main(void)``, which is required by the ISO C++ standards, as
opposed to the Zephyr default ``void main(void)``.
* Added no-throwing implementation of new operator to the C++ minimal
library.
* Added support for new operator with alignment request (C++17) to the C++
minimal library.
* Added GNU C++ standard library support with Picolibc when using a suitably
configured toolchain (e.g. the upcoming Zephyr SDK 0.16.0 release).
* Cache
* Introduced new Cache API
* ``CONFIG_HAS_ARCH_CACHE`` has been renamed to
:kconfig:option:`CONFIG_ARCH_CACHE`
* ``CONFIG_HAS_EXTERNAL_CACHE`` has been renamed to
:kconfig:option:`CONFIG_EXTERNAL_CACHE`
* DSP
* Introduced DSP (digital signal processing) subsystem with CMSIS-DSP as the
default backend.
* CMSIS-DSP now supports all architectures supported by Zephyr.
* File systems
* Added new API call `fs_mkfs`.
* Added new sample `samples/subsys/fs/format`.
* FAT FS driver has been updated to version 0.15 w/patch1.
* Added the option to disable CRC checking in :ref:`fcb_api` by enabling the
Kconfig option :kconfig:option:`CONFIG_FCB_ALLOW_FIXED_ENDMARKER`
and setting the `FCB_FLAGS_CRC_DISABLED` flag in the :c:struct:`fcb` struct.
* IPC
* Added :c:func:`ipc_rpmsg_deinit`, :c:func:`ipc_service_close_instance` and
:c:func:`ipc_static_vrings_deinit` functions
* Added deregister API support for icmsg backend
* Added a multi-endpoint feature to icmsg backend
* Added no-copy features to icmsg backend
* ISO-TP
* Rewrote the ISO-TP API to not reuse definitions from the CAN controller API.
* Logging
* Added support for logging on multiple domains.
* :kconfig:option:`CONFIG_LOG_PRINTK` is now by default enabled which means that
when logging is enabled then printk is by directed to the logging subsystem.
* Added option to use custom logging header.
* Management
* MCUmgr functionality deprecated in 3.1 has been removed:
CONFIG_FS_MGMT_UL_CHUNK_SIZE, CONFIG_IMG_MGMT_UL_CHUNK_SIZE,
CONFIG_OS_MGMT_ECHO_LENGTH
* MCUmgr fs_mgmt issue with erasing a file prior to writing the first block
of data has been worked around by only truncating/deleting the file data
if the file exists. This can help work around an issue whereby logging is
enabled and the command is sent on the same UART as the logging system, in
which a filesystem error was emitted.
* A MCUmgr bug when using the smp_svr sample with Bluetooth transport that
could have caused a stack overflow has been fixed.
* A MCUmgr issue with Bluetooth transport that could cause a deadlock of the
mcumgr thread if the remote device disconnected before the output message
was sent has been fixed.
* A MCUmgr img_mgmt bug whereby the state of an image upload could persist
when it was no longer valid (e.g. after an image erase command) has been
fixed.
* MCUmgr fs_mgmt command has been added that allows querying/listing the
supported hash/checksum types.
* MCUmgr Bluetooth transport will now clear unprocessed commands sent if a
remote device disconnects instead of processing them.
* A new MCUmgr transport function pointer has been added which needs
registering in ``smp_transport_init`` for removing invalid packets for
connection-orientated transports. If this is unimplemented, the function
pointer can be set to NULL.
* MCUmgr command handler definitions have changed, the ``mgmt_ctxt`` struct
has been replaced with the ``smp_streamer`` struct, the zcbor objects need
to replace ``cnbe`` object access with ``writer`` and ``cnbd`` object
access with ``reader`` to successfully build.
* MCUmgr callback system has been reworked with a unified singular interface
which supports status passing to the handler (:ref:`mcumgr_callbacks`).
* MCUmgr subsystem directory structure has been flattened and contents of the
lib subdirectory has been redistributed into following directories:
.. table::
:align: center
+----------------+-------------------------------------------+
| Subdirectory | MCUmgr area |
+================+===========================================+
| mgmt | MCUmgr management functions, group |
| | registration, and so on; |
+----------------+-------------------------------------------+
| smp | Simple Management Protocol processing; |
+----------------+-------------------------------------------+
| transport | Transport support and transport API; |
+----------------+-------------------------------------------+
| grp | Command groups, formerly lib/cmd; |
| | each group, which has Zephyr built in |
| | support has its own directory here; |
+----------------+-------------------------------------------+
| util | Utilities used by various subareas of |
| | MCUmgr. |
+----------------+-------------------------------------------+
Public API interfaces for above areas are now exported through zephyr_interface,
and headers for them reside in ``zephyr/mgmt/mcumgr/<mcumgr_subarea>/``.
For example to access mgmt API include ``<zephyr/mgmt/mcumgr/mgmt/mgmt.h>``.
Private headers for above areas can be accessed, when required, using paths:
``mgmt/mcumgr/mgmt/<mcumgr_subarea>/``.
* MCUmgr os_mgmt info command has been added that allows querying details on
the kernel and application, allowing application-level extensibility
see :ref:`mcumgr_os_application_info` for details.
* MCUMgr :kconfig:option:`CONFIG_APP_LINK_WITH_MCUMGR` has been removed as
it has not been doing anything.
* MCUmgr Kconfig option names have been standardised. Script
:zephyr_file:`scripts/utils/migrate_mcumgr_kconfigs.py` has been provided
to make transition to new Kconfig options easier.
Below table provides information on old names and new equivalents:

* MCUmgr responses where ``rc`` (result code) is 0 (no error) will no longer
be present in responses and in cases where there is only an ``rc`` result,
the resultant response will now be an empty CBOR map. The old behaviour can
be restored by enabling
:kconfig:option:`CONFIG_MCUMGR_SMP_LEGACY_RC_BEHAVIOUR`.
* MCUmgr now has log outputting on most errors from the included fs, img,
os, shell, stat and zephyr_basic group commands. The level of logging can be
controlled by adjusting: :kconfig:option:`CONFIG_MCUMGR_GRP_FS_LOG_LEVEL`,
:kconfig:option:`CONFIG_MCUMGR_GRP_IMG_LOG_LEVEL`,
:kconfig:option:`CONFIG_MCUMGR_GRP_OS_LOG_LEVEL`,
:kconfig:option:`CONFIG_MCUMGR_GRP_SHELL_LOG_LEVEL`,
:kconfig:option:`CONFIG_MCUMGR_GRP_STAT_LOG_LEVEL` and
:kconfig:option:`CONFIG_MCUMGR_GRP_ZBASIC_LOG_LEVEL`.
* MCUmgr img_mgmt has a new field which is sent in the final packet (if
:kconfig:option:`CONFIG_IMG_ENABLE_IMAGE_CHECK` is enabled) named ``match``
which is a boolean and is true if the uploaded data matches the supplied
hash, or false otherwise.
* MCUmgr img_mgmt will now skip receiving data if the provided hash already
matches the hash of the data present (if
:kconfig:option:`CONFIG_IMG_ENABLE_IMAGE_CHECK` is enabled) and finish the
upload operation request instantly.
* MCUmgr img_mgmt structs are now packed, which fixes a fault issue on
processors that do not support unaligned memory access.
* If MCUmgr is used with the shell transport and ``printk()`` functionality
is used, there can be an issue whereby the ``printk()`` calls output during
a MCUmgr frame receive, this has been fixed by default in zephyr by routing
``printk()`` calls to the logging system, For user applications,
:kconfig:option:`CONFIG_LOG_PRINTK` should be enabled to include this fix.
* A bug when MCUmgr shell transport is used (issue was observed over USB CDC
but could also occur with UART) whereby the default shell receive ring
buffer is insufficient has been fixed by making the default size 256 bytes
instead of 64 when the shell MCUmgr transport is selected.
* UpdateHub:
* The integrity check was reworked to allow use by other libraries. Since
then UpdateHub uses mbedTLS library as default crypto library.
* Added a new Storage Abstraction to isolate both flash operations and
MCUboot internals.
* The UpdateHub User API was moved as a Zephyr public API and the userspace
now is available. This added :c:func:`updatehub_confirm` and
:c:func:`updatehub_reboot` functions.
* LwM2M
* The ``lwm2m_senml_cbor_*`` files have been regenerated using zcbor 0.6.0.
* POSIX API
* Harmonized posix type definitions across the minimal libc, newlib and picolibc.
* Abstract ``pthread_t``, ``pthread_key_t``, ``pthread_cond_t``,
``pthread_mutex_t``, as ``uint32_t``.
* Defined :c:macro:`PTHREAD_KEY_INITIALIZER`, :c:macro:`PTHREAD_COND_INITIALIZER`,
:c:macro:`PTHREAD_MUTEX_INITIALIZER` to align with POSIX 1003.1.
* Allowed non-prefixed standard include paths with :kconfig:option:`CONFIG_POSIX_API`.
* I.e. ``#include <unistd.h>`` instead of ``#include <zephyr/posix/unistd.h>``.
* Primarily to ease integration with external libraries.
* Internal Zephyr code should continue to use prefixed header paths.
* Enabled ``eventfd()``, ``getopt()`` by default with :kconfig:option:`CONFIG_POSIX_API`.
* Moved / renamed header files to align with POSIX specifications.
* E.g. move ``fcntl.h``, ``sys/stat.h`` from the minimal libc into the
``include/zephyr/posix`` directory. Rename ``posix_sched.h`` to ``sched.h``.
* Move :c:macro:`O_ACCMODE`, :c:macro:`O_RDONLY`, :c:macro:`O_WRONLY`,
:c:macro:`O_WRONLY`, to ``fcntl.h``.
* Added :kconfig:option:`CONFIG_TIMER_CREATE_WAIT`, :kconfig:option:`CONFIG_MAX_PTHREAD_KEY_COUNT`,
:kconfig:option:`CONFIG_MAX_PTHREAD_COND_COUNT`, :kconfig:option:`CONFIG_MAX_PTHREAD_MUTEX_COUNT`.
* Defined :c:macro:`SEEK_SET`, :c:macro:`SEEK_CUR`, :c:macro:`SEEK_END`.
* SD Subsystem
* Added support for eMMC protocol in Zephyr.
- Speed modes up to HS400 are supported using 1.8v operation.
- Additional protocol tests have been added to verify eMMC functionality.
- Disk subsystem tests have been updated to function with eMMC.
* Card and host combinations that cannot utilize UHS (ultra high speed) mode
will now use 4 bit bus width when possible. This will greatly improve
performance for these systems.
* Settings
* Replaced all :c:func:`k_panic` invocations within settings backend
initialization with returning / propagating error codes.
* Shell
* New features:
* SHELL_AUTOSTART configuration option. When SHELL_AUTOSTART is set to n, the shell is not
started after boot but can be enabled later from the application code.
* Added support for setting the help description for each entry in a dictionary.
* Bugfix:
* Updated to clear command buffer when leaving bypass mode to prevent undefined behaviour
on consecutive shell operations.
* Set RX size default to 256 if shell MCUmgr is enabled.
* Fixed log message queue size for all backends.
* Documentation:
* Added information explaining commands execution.
* Utilities
* Added the linear range API to map values in a linear range to a range index
:zephyr_file:`include/zephyr/sys/linear_range.h`.
* Zbus
* Added the :ref:`zbus` to Zephyr.
* Channel-centric multi-paradigm (message-passing and publish-subscribe) communication message bus.
* Virtual Distributed Event Dispatcher.
* Observers can be listeners (synchronous) and subscribers (asynchronous).
* One-to-one, one-to-many, and many-to-many communications.
* Persistent messages distributed by shared-memory approach.
* Delivery guarantee only for listeners.
* Uses mutex to control channels access.
* Added the following samples:
* :ref:`zbus-hello-world-sample`
* :ref:`zbus-work-queue-sample`
* :ref:`zbus-dyn-channel-sample`
* :ref:`zbus-uart-bridge-sample`
* :ref:`zbus-remote-mock-sample`
* :ref:`zbus-runtime-obs-registration-sample`
* :ref:`zbus-benchmark-sample`
* Added zbus channels APIs:
* :c:func:`zbus_chan_pub`
* :c:func:`zbus_chan_read`
* :c:func:`zbus_chan_notify`
* :c:func:`zbus_chan_claim`
* :c:func:`zbus_chan_finish`
* :c:func:`zbus_chan_name`
* :c:func:`zbus_chan_msg`
* :c:func:`zbus_chan_const_msg`
* :c:func:`zbus_chan_msg_size`
* :c:func:`zbus_chan_user_data`
* :c:func:`zbus_chan_add_obs`
* :c:func:`zbus_chan_rm_obs`
* :c:func:`zbus_runtime_obs_pool`
* :c:func:`zbus_obs_set_enable`
* :c:func:`zbus_obs_name`
* :c:func:`zbus_sub_wait`
* :c:func:`zbus_iterate_over_channels`
* :c:func:`zbus_iterate_over_observers`
* Added the related configuration options:
* :kconfig:option:`CONFIG_ZBUS_CHANNEL_NAME`
* :kconfig:option:`CONFIG_ZBUS_OBSERVER_NAME`
* :kconfig:option:`CONFIG_ZBUS_STRUCTS_ITERABLE_ACCESS`
* :kconfig:option:`CONFIG_ZBUS_RUNTIME_OBSERVERS_POOL_SIZE`

time now.
Trusted Firmware-M
******************
* Updated to TF-M 1.7.0 (and MbedTLS 3.2.1).
* Initial attestation service has been disabled by default due to license
issues with the QCBOR dependency. To enable it, set the path for QCBOR via
``CONFIG_TFM_QCBOR_PATH`` or set the path to ``DOWNLOAD``.
* Firmware update sample removed pending update to 1.0 FWU service.
* psa_crypto sample removed pending resolution of PSA API conflicts w/MbedTLS.
zcbor
*****
Upgraded zcbor to 0.6.0. Among other things, this brings in a few convenient
changes for Zephyr:
* In the zcbor codebase, the ``ARRAY_SIZE`` macro has been renamed to
``ZCBOR_ARRAY_SIZE`` to not collide with Zephyr's :c:macro:`ARRAY_SIZE` macro.
* The zcbor codebase now better supports being used in C++ code.
The entire release notes can be found at
https://github.com/zephyrproject-rtos/zcbor/blob/0.6.0/RELEASE_NOTES.md
Documentation
*************
* Upgraded to Doxygen 1.9.6.
* It is now possible to link to Kconfig search results.
