Changelog

The following sections provide detailed lists of changes by component.

IDE, OS, and tool support

• Updated:
  • The required `SEGGER J-Link`_ version to v8.10f.
  • The :ref:`installing_vsc` section on the :ref:`installation` page with the Windows-only requirement to install SEGGER USB Driver for J-Link.

Board support

|no_changes_yet_note|

Build and configuration system

• Removed support for the deprecated multi-image builds (parent-child images) functionality. All |NCS| projects must now use :ref:`sysbuild`. See :ref:`child_parent_to_sysbuild_migration` for an overview of differences with parent-child image and how to migrate.

Bootloaders and DFU

|no_changes_yet_note|

Developing with nRF91 Series

|no_changes_yet_note|

Developing with nRF70 Series

• :ref:`ug_nrf70_developing_fw_patch_ext_flash`

  • Removed support for storing the nRF70 firmware patches in external flash without the :ref:`partition_manager`.

Working with nRF54H Series

• Removed the note on installing SEGGER USB Driver for J-Link on Windows from the :ref:`ug_nrf54h20_gs` page and moved its contents to the `nRF Util prerequisites`_ documentation. The Windows-only requirement to install the SEGGER USB Driver for J-Link is now mentioned in the :ref:`installing_vsc` section on the :ref:`installation` page.

Developing with nRF54L Series

• Added HMAC SHA-256 with a 128-bit key type to KMU, as detailed in the :ref:`ug_nrf54l_crypto_kmu_supported_key_types` documentation section.

|no_changes_yet_note|

DECT NR+

|no_changes_yet_note|

  • :ref:`ug_matter_debug_snippet`.
• Disabled the :ref:`mpsl` before performing factory reset to speed up the process.

Matter fork

|no_changes_yet_note|

nRF IEEE 802.15.4 radio driver

|no_changes_yet_note|

Thread

|no_changes_yet_note|

Zigbee

• Fixed the :file:`zb_add_ota_header.py` script to allow a patch version higher than 9 in an APPLICATION_VERSION_STRING.

Wi-Fi

|no_changes_yet_note|

Applications

This section provides detailed lists of changes by :ref:`application <applications>`.

Machine learning

• Updated the application to enable the :ref:`Zephyr Memory Storage (ZMS) <zephyr:zms_api>` file system for the :ref:`zephyr:nrf54h20dk_nrf54h20` board.

Asset Tracker v2

• Updated the application to use the :ref:`lib_downloader` library instead of the deprecated :ref:`lib_download_client` library.

Connectivity Bridge

|no_changes_yet_note|

IPC radio firmware

• Updated the application to enable the :ref:`Zephyr Memory Storage (ZMS) <zephyr:zms_api>` file system in all devices that contain MRAM, such as the nRF54H Series devices.

Matter Bridge

• Enabled SUIT DFU support for the :ref:`matter_bridge_app` application. Currently, only the Matter OTA protocol is fully supported for SUIT DFU purposes.
• Enabled Link Time Optimization (LTO) by default for the release configuration.

nRF5340 Audio

|no_changes_yet_note|

nRF Desktop

• Updated:
  • The :ref:`nrf_desktop_failsafe` to use the Zephyr :ref:`zephyr:hwinfo_api` driver for getting and clearing the reset reason information (see the :c:func:`hwinfo_get_reset_cause` and :c:func:`hwinfo_clear_reset_cause` functions). The Zephyr :ref:`zephyr:hwinfo_api` driver replaces the dependency on the nrfx reset reason helper (see the :c:func:`nrfx_reset_reason_get` and :c:func:`nrfx_reset_reason_clear` functions).
  • The release configuration for the :ref:`zephyr:nrf54h20dk_nrf54h20` board target to enable the :ref:`nrf_desktop_failsafe` (see the :ref:`CONFIG_DESKTOP_FAILSAFE_ENABLE <config_desktop_app_options>` Kconfig option).
  • Enabled Link Time Optimization (:kconfig:option:`CONFIG_LTO` and :kconfig:option:`CONFIG_ISR_TABLES_LOCAL_DECLARATION`) by default for an nRF Desktop application image. LTO was also explicitly enabled in configurations of other images built by sysbuild (bootloader, network core image).
  • Application configurations for nRF54L05, nRF54L10, and nRF54L15 SoCs to use Fast Pair PSA cryptography (:kconfig:option:`CONFIG_BT_FAST_PAIR_CRYPTO_PSA`). Using PSA cryptography improves security and reduces memory footprint. Also increased the size of the Bluetooth receiving thread stack (:kconfig:option:`CONFIG_BT_RX_STACK_SIZE`) to prevent stack overflows.
  • Application configurations for nRF52810 and nRF52820 SoCs to reduce memory footprint:
    • Disabled Bluetooth long workqueue (:kconfig:option:`CONFIG_BT_LONG_WQ`).
    • Limited the number of key slots in the PSA Crypto core to 10 (:kconfig:option:`CONFIG_MBEDTLS_PSA_KEY_SLOT_COUNT`).
• Added:
  • System Power Management for the :ref:`zephyr:nrf54h20dk_nrf54h20` board target on the application and radio cores. The application still has high power consumption as the Bluetooth LE controller running on the radio core requires disabling MRAM latency (:kconfig:option:`CONFIG_MRAM_LATENCY_AUTO_REQ`). Enabling MRAM latency makes the Bluetooth LE controller unstable.
  • Application configurations for the nRF54L05 and nRF54L10 SoCs (emulated on the nRF54L15 DK). The configurations are supported through nrf54l15dk/nrf54l10/cpuapp and nrf54l15dk/nrf54l05/cpuapp board targets. For details, see the :ref:`nrf_desktop_board_configuration`.
  • The dongle_small configuration for the nRF52833 DK. The configuration enables logs and mimics the dongle configuration used for small SoCs.

nRF Machine Learning (Edge Impulse)

|no_changes_yet_note|

Serial LTE modem

• Added an overlay :file:`overlay-memfault.conf` file to enable Memfault. For more information about Memfault features in |NCS|, see :ref:`mod_memfault`.
• Updated the application to use the :ref:`lib_downloader` library instead of the deprecated :ref:`lib_download_client` library.

Thingy:53: Matter weather station

• Enabled Link Time Optimization (LTO) by default for the release configuration.

Samples

This section provides detailed lists of changes by :ref:`sample <samples>`.

Amazon Sidewalk samples

|no_changes_yet_note|

Bluetooth samples

• Added support for the nrf54l15dk/nrf54l05/cpuapp and nrf54l15dk/nrf54l10/cpuapp board targets in the following samples:

  • :ref:`bluetooth_central_hids`
  • :ref:`peripheral_hids_keyboard`

• Updated the configurations of the non-secure nrf5340dk/nrf5340/cpuapp/ns board target in the following samples to properly use the TF-M profile instead of the predefined minimal TF-M profile:

  • :ref:`bluetooth_central_hids`
  • :ref:`peripheral_hids_keyboard`
  • :ref:`peripheral_hids_mouse`

  This change results from the Bluetooth subsystem transition to the PSA cryptographic standard. The Bluetooth stack can now use the PSA crypto API in the non-secure domain as all necessary TF-M partitions are configured properly.

    • :ref:`bluetooth_mesh_silvair_enocean`
    • :ref:`bluetooth_mesh_light_dim`
    • :ref:`bluetooth_mesh_light`
    • :ref:`bluetooth_mesh_light_lc`

• Updated the following samples to include the value of the :kconfig:option:`CONFIG_BT_COMPANY_ID` option in the Firmware ID:

  • :ref:`ble_mesh_dfu_distributor`
  • :ref:`ble_mesh_dfu_target`

Cellular samples

• Updated the following samples to use the :ref:`lib_downloader` library instead of the :ref:`lib_download_client` library:

• :ref:`nrf_cloud_multi_service` sample:

  • Fixed:
    • Wrong header naming in :file:`provisioning_support.h` that was causing build errors when :file:`sample_reboot.h` was included in other source files.
    • An issue with an uninitialized variable in the :c:func:`handle_at_cmd_requests` function.
    • An issue with the too small :kconfig:option:`CONFIG_COAP_EXTENDED_OPTIONS_LEN_VALUE` Kconfig value in the :file:`overlay-coap_nrf_provisioning.conf` file.
    • Slow Wi-Fi connectivity startup by selecting TFM_SFN instead of TFM_IPC.
    • The size of TLS credentials buffer for Wi-Fi connectivity to allow installing both AWS and CoAP CA certificates.

• :ref:`lte_sensor_gateway` sample:

Networking samples

• Updated:
  • The :kconfig:option:`CONFIG_HEAP_MEM_POOL_SIZE` Kconfig option value to 1280 for all networking samples that had it set to a lower value. This is a requirement from zephyr and removes a build warning.
