| made it independent of :kconfig:option:`CONFIG_BT_BAP_SCAN_DELEGATOR`. |
| * Modified :c:func:`bt_bap_stream_send` to no longer take a timestamp as parameter, |
| and added :c:func:`bt_bap_stream_send_ts` that does. |
| * Modified :c:func:`bt_cap_stream_send` to no longer take a timestamp as parameter, |
| and added :c:func:`bt_cap_stream_send_ts` that does. |
| * Assigned number values have been moved from :file:`include/zephyr/bluetooth/audio/lc3.h` to |
| :file:`include/zephyr/bluetooth/audio/audio.h` and the ``LC3`` infix have been removed. |

| |
| * Host |
| |
| * Added ``recycled()`` callback to :c:struct:`bt_conn_cb`, which notifies listeners when a |
| connection object has been freed, so it can be utilized for different purposes. No guarantees |
| are made to what listener will be granted the object, as only the first claim is served. |
| * Modified :c:func:`bt_iso_chan_send` to no longer take a timestamp as parameter, |
| and added :c:func:`bt_iso_chan_send_ts` that does. |

| It is now possible to run the BLE controller or 802.15.4 driver in the net core, and application |
| and BT host in the app core. |
| |
| * The nrf*_bsim simulated targets now include models of the UART peripheral. It is now possible |

| Build system and infrastructure |
| ******************************* |
| |
| * Added functionality for Link Time Optimization. |
| This change includes interrupt script generator rebuilding and adds the |
| following Kconfig options: |
| |
| - :kconfig:option:`CONFIG_ISR_TABLES_LOCAL_DECLARATION`: |
| LTO compatible interrupt tables parser |
| - :kconfig:option:`CONFIG_LTO`: Enable Link Time Optimization |
| |
| Currently the LTO compatible interrupt tables parser is only supported by ARM architectures and |
| GCC compiler/linker. |
| See pull request :github:`66392` for details. |
| |
| * Dropped the ``COMPAT_INCLUDES`` option. It was unused since Zephyr v3.0. |
| |
| * Fixed an issue whereby board revision ``0`` did not include overlay files for that revision. |
| |
| * Added ``PRE_IMAGE_CMAKE`` and ``POST_IMAGE_CMAKE`` hooks to sysbuild modules, which allows for |
| modules to run code after and before each image's cmake invocation. |
| |
| * Added :kconfig:option:`CONFIG_ROM_END_OFFSET` option which allows reducing the size of an image. |
| This is intended for use with firmware signing scripts which add additional data to the end of |
| images outside of the build itself. |
| |
| * Added MCUboot image size reduction to sysbuild images which include MCUboot. This prevents |
| issues with building firmware images that are too large for MCUboot to swap. |
| |
| * Deprecated :kconfig:option:`CONFIG_BOOTLOADER_SRAM_SIZE`. Users of this should transition to |
| having RAM set up properly in their board devicetree files. |
| |
| * Fixed an issue whereby shields were processed in order of the root they resided in rather than |
| the order they were supplied to cmake in. |
| |
| * Fixed an issue whereby using some shields with sysbuild would cause a cmake Kconfig error. |
| |
| * Fixed an issue where the macros ``_POSIX_C_SOURCE`` and ``_XOPEN_SOURCE`` would be defined |
| globally when building with Picolibc or for the native (``ARCH_POSIX``) targets. |
| After this change users may need to define them for their own applications or libraries. |
| |
| * Added support for sysbuild setting a signing script (``SIGNING_SCRIPT``). See |
| :ref:`west-extending-signing` for details. |
| |
| * Added support for ``FILE_SUFFIX`` in the build system which allows for adding suffixes to |
| application Kconfig fragment file names and devicetree overlay file names. See |
| :ref:`application-file-suffixes` and :ref:`sysbuild_file_suffixes` for details. |
| |
| * Deprecated ``CONF_FILE`` ``prj_<build>.conf`` build type. |
| |
| * Added `-Wdouble-promotion` as a default warning when compiling to warn developers with |
| single-precision floats easily being promoted to double-precision. |
| |
| Drivers and Sensors |
| ******************* |
| |
| * ADC |
| |
| * Power Management for ADC is now supported on STM32 devices. |
| * STM32 ADC driver now supports mixing shared and separate IRQs (for instance on STM32G473 |
| which has 5 ADCs, ADC1 and ADC2 share one IRQ while ADC3, ADC4 and ADC5 each have unique IRQs). |
| Enabling all instances in the same application is not possible on such devices as of now. |
| |

| * Added a driver :file:`drivers/ethernet/eth_nxp_enet.c` for NXP ENET which is a rework of |
| the old driver :file:`drivers/ethernet/eth_mcux.c`. The old driver became |
| unmaintainable due to fundamental problems with the lack of PHY abstraction. The new driver |
| is still experimental and requires maturation. Eventually the old driver will be deprecated |
| and this new driver will be supported instead. |
| |
| * Flash |
| |
| * Redesigned the Atmel SAM controller to fully utilize flash page layout. |
| * ``spi_nor`` driver now sleeps between polls in ``spi_nor_wait_until_ready``. If this is not |
| desired (For example due to ROM constraints in a bootloader), |
| :kconfig:option:`CONFIG_SPI_NOR_SLEEP_WHILE_WAITING_UNTIL_READY` can be disabled. |
| * Flash readout protection configuration was added on STM32G4 and STM32L4 series. |
| |

| |
| * Added GNSS device driver API and subsystem for parsing and publishing location, |
| datetime, and satellite information, enabled by |
| :kconfig:option:`CONFIG_GNSS` and :kconfig:option:`CONFIG_GNSS_SATELLITES`. |
| The GNSS subsystem and device drivers are based on the :ref:`modem` subsystem, |
| using the ``modem_pipe`` module, modem backends, and ``modem_chat`` module to |
| communicate with the modems. For systems which already contain a cellular modem, |
| adding a GNSS modem is very efficient due to the reuse of subsystems. |
| |
| * Added GNSS-specific, safe, string-to-integer parsing utilities, enabled by |
| :kconfig:option:`CONFIG_GNSS_PARSE`. |
| |
| * Added NMEA0183 parsing utilities, enabled by |
| :kconfig:option:`CONFIG_GNSS_NMEA0183`. |
| |

| devicetree compatible :dtcompatible:`gnss-nmea-generic`. |
| |
| * Added fully featured device driver for the Quectel LCX6G series GNSS modems, |
| matching the devicetree compatibles :dtcompatible:`quectel,lc26g`, |
| :dtcompatible:`quectel,lc76g` and :dtcompatible:`quectel,lc86g`. |

| |
| * I3C |
| |
| * The Legacy Virtual Register defines have been renamed from ``I3C_DCR_I2C_*`` |
| to ``I3C_LVR_I2C_*``. |
| |
| * Added the ability to specify a start address when searching for a free I3C |
| address to be reserved. This requires a new function argument to |
| :c:func:`i3c_addr_slots_next_free_find`. |
| |
| * Added a field named ``num_xfer`` in :c:struct:`i3c_msg` and |
| :c:struct:`i3c_ccc_taget_payload` as an output to indicate the actual |
| number of bytes transferred. |
| |
| * Cadence I3C driver (:file:`drivers/i3c/i3c_cdns.c`): |
| |
| * Added support to handle controller abort where the target does not emit |
| end of data for register read but continues sending data. |
| |
| * Updated the timeout calculation to be coupled with CPU speed instead of |
| a fixed number of retries. |
| |
| * NXP MCUX I3C driver (:file:`drivers/i3c/i3c_mcux.c`): |
| |
| * Fixed ``mcux_i3c_config_get()`` not returning the configuration to the caller. |

| * Improved the FIFO read routine to support higher transfer rates. |
| |
| * Removed the infinite wait for MCTRLDONE in auto IBI. |
| |
| * Added ``disable-open-drain-high-pp`` property to |
| :dtcompatible:`nxp,mcux-i3c`, which allows alternative high time for |
| open-drain clock. |
| |
| * IEEE 802.15.4 |
| |
| * Removed :kconfig:option:`CONFIG_IEEE802154_SELECTIVE_TXPOWER` Kconfig option. |

| * Added support for IPv6 Neighbor reachability hints, allowing to reduce |
| ICMPv6 traffic for active connections. |
| |
| * IP: |
| |
| * Fixed L3/L4 checksum calculation/validation for IP-fragmented packets on |
| interfaces that support checksum offload. |
| * Fixed net_context not being set on IP fragmented packets, preventing send |
| callback from being called. |
| * It is now possible to have separate IPv4 TTL value and IPv6 hop limit value for |
| unicast and multicast packets. This can be controlled in each socket via |
| :c:func:`setsockopt` API. |

| to/from loopback address on non-loopback interfaces are dropped. |
| * Added new functions to verify if IPv6 address is site local or global. |
| * Added support for setting peer IP address in :c:struct:`net_pkt` structure |

| valid address in offloaded case. |
| |
| * LwM2M: |
| |
| * Added :kconfig:option:`CONFIG_LWM2M_UPDATE_PERIOD` which configures the LwM2M |

| with prefixed path. |
| * Added LwM2M-specific macros for object initialization during boot. |
| * Several other minor bugfixes ans improvements. |
| |
| * Misc: |
| |

| |
| * Added :c:func:`mqtt_sn_get_topic_name` API function. |
| * Fixed handling of incoming Register messages when wildcard subscription is used. |
| |
| * OpenThread: |
| |

| |
| * Shell: |
| |
| * Refactored networking shell module so that instead of large single file, it |

| * Added ``net sockets`` command to print information about open sockets and |
| socket services. |

| |
| Libraries / Subsystems |
| ********************** |
| |
| * Management |
| |
| * Fixed an issue in MCUmgr image management whereby erasing an already erased slot would return |
| an unknown error. It now returns success. |
| |
| * Fixed MCUmgr UDP transport structs being statically initialised. This results in about a |
| ~5KiB flash saving. |
| |
| * Fixed an issue in MCUmgr which would cause a user data buffer overflow if the UDP transport was |
| enabled on IPv4 only but IPv6 support was enabled in the kernel. |
| |
| * Implemented datetime functionality in MCUmgr OS management group. This makes use of the RTC |
| driver API. |
| |
| * Fixed an issue in MCUmgr console UART input whereby the FIFO would be read outside of an ISR, |
| which is not supported in the next USB stack. |
| |
| * Fixed an issue whereby the ``mcuboot erase`` DFU shell command could be used to erase the |
| MCUboot or currently running application slot. |
| |
| * Fixed an issue whereby messages that were too large to be sent over the UDP transport would |
| wrongly return :c:enum:`MGMT_ERR_EINVAL` instead of :c:enum:`MGMT_ERR_EMSGSIZE`. |
| |
| * Fixed an issue where confirming an image in Direct XIP mode would always confirm the image in |
| the primary slot even when executing from the secondary slot. Now the currently active image is |
| always confirmed. |
| |
| * Added support for retrieving registered command groups, to support registering and deregistering |
| default command groups at runtime, allowing an application to support multiple implementations |
| for the same command group. |
| |
| * Fixed an issue in MCUmgr FS management whereby the semaphore lock would not be given if an |
| error was returned, leading to a possible deadlock. |
| |
| * Added support for custom payload MCUmgr handlers. This can be enabled with |
| :kconfig:option:`CONFIG_MCUMGR_MGMT_CUSTOM_PAYLOAD`. |
| |
| * Fixed an issue in MCUmgr image management whereby an error would be returned if a command was |
| sent to erase the slot which was already erased. |
| |
| * Added support for image slot size checking to ensure an update can be utilised by MCUboot. |
| This can be performed by using sysbuild when building both application and MCUboot by enabling |
| :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_TOO_LARGE_SYSBUILD` or by use of bootloader information |
| sharing from MCUboot by enabling |
| :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_TOO_LARGE_BOOTLOADER_INFO`. |
| |
| * Logging |
| |
| * Added an option to remove string literals from the binary when dictionary-based logging is used. |
| |
| * Optimized the most common logging messages (strings with up to 2 numeric arguments). Optimization |
| is done for code size (significant gain seen on riscv32) and performance. |
| |
| * Extended logging frontend API to optionally implement dedicated functions for optimized messages. |
| Optional API is enabled by :kconfig:option:`CONFIG_LOG_FRONTEND_OPT_API`. |
| |
| * Added support for runtime message filtering for the logging frontend. |
| |
| * Added option to support multiple instances of the UART logging backend. |
| |
| * Fixed userspace issue for :c:func:`printk` when :kconfig:option:`CONFIG_LOG_PRINTK` is enabled. |
| |
| * Added compile time detection of logging messages that use character pointers for ``%p``. |
| It must be avoided when dictionary-based logging is used and strings are stripped from the |
| binary. When an erroneous case is detected, the user message is replaced with an error message |
| that suggests pointer casting must be added. |
| |
| * Removed remaining references to v2 logging. Renamed :c:func:`log2_generic` to :c:func:`log_generic`. |
| |
| * Modem modules |
| |
| * Added ``TRANSMIT_IDLE`` event to the ``modem_pipe`` module which notifies the user of the pipe |
| that the backend has transmitted all bytes placed in its buffer using |
| :c:func:`modem_pipe_transmit()`. |
| The event greatly increases the efficiency of transmitting large quantities of data if used to |
| dynamically manage the delay between calls to :c:func:`modem_pipe_transmit()`. |
| |
| * Implemented ``TRANSMIT_IDLE`` event in all modem backends. |
| |
| * Extended all modem modules to utilize the ``TRANSMIT_IDLE`` event to dynamically manage the delay |
| between calls to :c:func:`modem_pipe_transmit()`. This addition reduced the utilization of the |
| system workqueue while transmitting large, continuous quantities of data, by 86%, while only |
| reducing the throughput by 12%. This optimization additionally allows lower priority threads, |
| like the deferred logging thread, to run during the transmission (it was blocked by the |
| relentless, continuous calls to :c:func:`modem_pipe_transmit()`). |
| |
| * Improved ``modem_pipe`` event dispatching. The ``modem_pipe`` module now invokes the |
| ``RECEIVE_READY`` event every time the pipe is attached using :c:func:`modem_pipe_attach()` |
| if it has data ready to be read, and always invokes ``TRANSMIT_IDLE`` when the pipe is |
| either opened or attached. This ensures event driven users of the modem pipe module can |
| rely solely on the events to start read/transmit work. A test suite has been added to |
| complement the improvements. |
| |
| * Extended ``modem_cmux`` module to support acting both as DTE (user application) and DCE (modem). |
| With this addition, two Zephyr applications can communicate with each other through their |
| respective ``modem_cmux`` instances. |
| |
| * Picolibc |
| |
| * Updated to version 1.8.6. This removes the :c:macro:`_POSIX_C_SOURCE` definition from the build |
| system, so applications will need to add this if they use APIs outside of the Zephyr |
| requirements. |
| |
| * Added new :c:func:`printf` modes, :kconfig:option:`CONFIG_PICOLIBC_IO_LONG_LONG` and |
| :kconfig:option:`CONFIG_PICOLIBC_IO_MINIMAL`. These provide applications with finer grained |
| control over the level of support provided by the library to control text space usage. By |
| default, the correct level of support is selected based upon other configuration parameters. |
| |
| * Added :kconfig:option:`CONFIG_PICOLIBC_ASSERT_VERBOSE`. This option, which is false by default, |
| controls whether the :c:func:`assert` function displays verbose information, including the file |
| name, line number, function name and failing expression text, when the assertion fails. Leaving |
| this disabled saves text space. |
| |
| * :kconfig:option:`CONFIG_THREAD_LOCAL_STORAGE` can now be disabled while using Picolibc. This is |
| very helpful in diagnosing issues when using Picolibc as those are often caused by enabling TLS |
| and not caused by using the library itself. |
| |
| * Numerous improvements in the library including code-size reductions in areas like printf and |
| ctype and various fixes in the math library. |
| |
| * Power management |
| |
| * Introduced Atmel SAM SUPC functions to allow wakeup sources and poweroff. |
| * STM32F4 devices now support stop mode thanks to the use of a RTC based idle timer which |
| keeps track of tick evolution while cortex systick is off. |
| |
| * :c:func:`pm_device_runtime_put_async()` got a parameter to specify a minimum delay to |
| the operation. This is useful to avoid multiple states transitions when a device is used. |
| |
| * Devices that don't need to block when suspending or resuming can now be defined as ISR |
| safe (``PM_DEVICE_ISR_SAFE``). For those devices, Zephyr is able to reduce RAM consumption |
| and runtime device power management can be safely used from interrupts. |
| |
| * Optimizations in device runtime power management. :c:func:`pm_device_runtime_get` and |
| :c:func:`pm_device_runtime_put` no longer wait for a pending operation to be concluded if it is still |
| in the work queue. In this case, the pending work is just canceled and the device state updated. |
| |
| * The Kconfig options below were added to customize the initialization priority of different |
| power domains. |
| |
| * :kconfig:option:`CONFIG_POWER_DOMAIN_GPIO_INIT_PRIORITY` |
| * :kconfig:option:`CONFIG_POWER_DOMAIN_GPIO_MONITOR_INIT_PRIORITY` |
| * :kconfig:option:`CONFIG_POWER_DOMAIN_INTEL_ADSP_INIT_PRIORITY` |
| |
| * Crypto |
| |
| * Mbed TLS updated to 3.5.2. Full release notes can be found in: |
| https://github.com/Mbed-TLS/mbedtls/releases/tag/v3.5.2 |
| |
| * Retention |
| |
| * Fixed issue whereby :kconfig:option:`CONFIG_RETENTION_BUFFER_SIZE` values over 256 would cause |
| an infinite loop due to use of 8-bit variables. |
| |
| * SD |
| |
| * Added support for SDIO devices. |
| |
| * Storage |
| |
| * File systems: LittleFS module has been updated to version 2.8.1. |
| |
| * Following Flash Map API macros, marked in 3.2 as deprecated, have been removed: |
| ``FLASH_AREA_ID``, ``FLASH_AREA_OFFSET``, ``FLASH_AREA_SIZE``, |
| ``FLASH_AREA_LABEL_EXISTS`` and ``FLASH_AREA_DEVICE``. |
| |
| * POSIX API |
| |
| * Completed support for ``POSIX_THREADS_EXT``, ``XSI_THREADS_EXT``, |
| ``POSIX_CLOCK_SELECTION``, and ``POSIX_SEMAPHORES`` Option Groups. |
| |
| * Completed support for ``_POSIX_MESSAGE_PASSING`` and |
| ``_POSIX_PRIORITY_SCHEDULING`` Options. |
| |
| * Fixed Coverity-CID 211585, 334906, 334909, and 340851. |
| |
| * Improved structure and accuracy of POSIX documentation. |
| |
| * Improved navigation and organization of POSIX Kconfig options. |
| |
| * Added support to allocate and free stacks up to 8 MB with pthread_attr_t. |
| |
| * Added support for deferred and asynchronous thread cancellation. |
| |
| * Added dining philosophers sample application. |
| |
| * Added support for named semaphores. |
| |
| * Added a top-level ``posix`` command in the Zephyr shell. Zephyr shell utilities for |
| the POSIX API can be added as subcommands (e.g. ``posix uname -a``) |
| |
| * Added support for async thread cancellation and ``SIGEV_THREAD``, ``CLOCK_REALTIME``. |
| |
| * Added compile-time-constant sysconf() implementation. |
| |
| * LoRa/LoRaWAN |
| |
| * Added LoRaWAN remote multicast support with :kconfig:option:`CONFIG_LORAWAN_REMOTE_MULTICAST` |
| in preparation for OTA firmware upgrade support. |
| |
| * ZBus |
| |
| * Replaced mutexes with semaphores to lock channels and implement the Highest Locker Protocol (HLP) |
| priority boost for the zbus operations. This feature avoids priority inversions and preemptions, |
| making the VDED delivery process faster and more consistent. (:github:`63183`) |
| |
| * Fixed documentation for :c:func:`zbus_chan_add` and :c:func:`zbus_chan_rm` adding the timeout |
| argument. (:github:`65544`) |
| |
| * Fixed warning when mixing C and C++ files using zbus. (:github:`65222`) |
| |
| * :c:macro:`ZBUS_CHANNEL_DEFINE` macro is now compatible with C++. (:github:`65196`) |
| |
| * Fixed parameter order of net buf pool fixed definition. (:github:`65039`) |
| |
| * Refactored the benchmark sample, adding message subscribers. (:github:`64524`) |
| |
| * Renamed ``CONFIG_ZBUS_MSG_SUBSCRIBER_NET_BUF_DYNAMIC`` and |
| ``CONFIG_ZBUS_MSG_SUBSCRIBER_NET_BUF_STATIC`` to |
| :kconfig:option:`CONFIG_ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_DYNAMIC` and |
| :kconfig:option:`CONFIG_ZBUS_MSG_SUBSCRIBER_BUF_ALLOC_STATIC`. (:github:`65632`) |
