  features. If you feel like something new can be useful to a user, put it
  under "Other Enhancements" in the first paragraph, if you feel like something
  is worth mentioning in the project media (release blog post, release
  livestream) put it under "Major enhancement".
..
  If you are describing a feature or functionality, consider adding it to the

  No list of bugfixes, minor changes, those are already in the git log, this is

Zephyr 4.2.0
############

We are pleased to announce the release of Zephyr version 4.2.0.

Major enhancements with this release include:

**Initial Support for Renesas RX**
  The Renesas RX architecture is now supported, including a QEMU-based
  :zephyr:board:`board target <qemu_rx>`.

**USB Video Class Driver**
  The USB device stack now supports USB Video Class (UVC) allowing camera devices and other
  image/video sources to be exposed as standard USB video devices. See :zephyr:code-sample:`uvc` to
  get started.

**Twister Power Harness**
  A :ref:`new Twister harness <twister_power_harness>` enables measurement of the power consumption
  of the device under test and ensures it remains within a given tolerance.

**MQTT 5.0**
  The networking stack now includes full support for the :ref:`MQTT 5.0 <mqtt_socket_interface>`
  protocol.

**Bluetooth Classic improvements**
  The Bluetooth Classic stack now includes support for **Hands-Free Profile** (HFP) for both Audio
  Gateway (AG) and Hands-Free (HF) roles.

**Zbus**
  The :ref:`Zbus library <zbus>` graduates to stable status with the release of API version v1.0.0.

**Expanded Board Support**
  Support for 96 :ref:`new boards <boards_added_in_zephyr_4_2>` and 22
  :ref:`new shields <shields_added_in_zephyr_4_2>` has been added in this release.

An overview of the changes required or recommended when migrating your application from Zephyr
v4.1.0 to Zephyr v4.2.0 can be found in the separate :ref:`migration guide<migration_4.2>`.

The following sections provide detailed lists of changes by component.

API Changes
***********

Removed APIs and options
========================

* Removed the deprecated ``net_buf_put()`` and ``net_buf_get()`` API functions.

* Removed the deprecated ``include/zephyr/net/buf.h`` header file.

* Removed the ``--disable-unrecognized-section-test`` Twister option. Test has been removed and the
  option became the default behavior.

* Removed the deprecated ``kscan`` subsystem.

* Removed :dtcompatible:`meas,ms5837` and replaced with :dtcompatible:`meas,ms5837-30ba`
  and :dtcompatible:`meas,ms5837-02ba`.

* Removed the ``get_ctrl`` driver API from :c:struct:`video_driver_api`.

* Removed ``CONFIG_I3C_USE_GROUP_ADDR`` and support for group addresses for I3C devices.

Deprecated APIs and options
===========================

* The scheduler Kconfig options CONFIG_SCHED_DUMB and CONFIG_WAITQ_DUMB were
  renamed and deprecated. Use :kconfig:option:`CONFIG_SCHED_SIMPLE` and
  :kconfig:option:`CONFIG_WAITQ_SIMPLE` instead.

* The :kconfig:option:`CONFIG_LWM2M_ENGINE_MESSAGE_HEADER_SIZE` Kconfig option has been removed.
  The required header size should be included in the message size, configured using
  :kconfig:option:`CONFIG_LWM2M_COAP_MAX_MSG_SIZE`. Special care should be taken to ensure that
  the CoAP block size used (:kconfig:option:`CONFIG_LWM2M_COAP_BLOCK_SIZE`) can fit the given
  message size with headers. Previous headroom was 48 bytes.

* TLS credential type ``TLS_CREDENTIAL_SERVER_CERTIFICATE`` was renamed and
  deprecated, use :c:enumerator:`TLS_CREDENTIAL_PUBLIC_CERTIFICATE` instead.

* ``arduino_uno_r4_minima`` and ``arduino_uno_r4_wifi`` board targets have been deprecated in favor
  of a new ``arduino_uno_r4`` board with revisions (``arduino_uno_r4@minima`` and
  ``arduino_uno_r4@wifi``).

* ``esp32c6_devkitc`` board target has been deprecated and renamed to
  ``esp32c6_devkitc/esp32c6/hpcore``.

* ``xiao_esp32c6`` board target has been deprecated and renamed to
  ``xiao_esp32c6/esp32c6/hpcore``.

* :kconfig:option:`CONFIG_HAWKBIT_DDI_NO_SECURITY` Kconfig option has been
  deprecated, because support for anonymous authentication had been removed from the
  hawkBit server in version 0.8.0.

* The :kconfig:option:`CONFIG_BT_CONN_TX_MAX` Kconfig option has been deprecated. The number of
  pending TX buffers is now aligned with the :kconfig:option:`CONFIG_BT_BUF_ACL_TX_COUNT` Kconfig
  option.

* The :kconfig:option:`CONFIG_CRYPTO_TINYCRYPT_SHIM` Kconfig option has been removed. It
  was deprecated since Zephyr 4.0, and users were advised to migrate to alternative
  crypto backends.

* The :kconfig:option:`CONFIG_BT_MESH_USES_TINYCRYPT` Kconfig option has been removed. It
  was deprecated since Zephyr 4.0. Users were advised to use
  :kconfig:option:`CONFIG_BT_MESH_USES_MBEDTLS_PSA` or
  :kconfig:option:`CONFIG_BT_MESH_USES_TFM_PSA` instead.

Stable API changes in this release
==================================

* The API signature of ``net_mgmt`` event handler :c:type:`net_mgmt_event_handler_t`
  and request handler :c:type:`net_mgmt_request_handler_t` has changed. The event value
  type is changed from ``uint32_t`` to ``uint64_t``.

New APIs and options
====================

..
  Link to new APIs here, in a group if you think it's necessary, no need to get
  fancy just list the link, that should contain the documentation. If you feel
  like you need to add more details, add them in the API documentation code
  instead.

Other notable changes
*********************

..
  Any more descriptive subsystem or driver changes. Do you really want to write
  a paragraph or is it enough to link to the api/driver/Kconfig/board page above?

* Added support for Armv8.1-M MPU's PXN (Privileged Execute Never) attribute.
  With this, the MPU attributes for ``__ramfunc`` and ``__ram_text_reloc`` were modified such that,
  PXN attribute is set for these regions if compiled with ``CONFIG_ARM_MPU_PXN`` and ``CONFIG_USERSPACE``.
  This results in a change in behavior for code being executed from these regions because,
  if these regions have pxn attribute set in them, they cannot be executed in privileged mode.

* Removed support for Nucleo WBA52CG board (``nucleo_wba52cg``) since it is NRND (Not Recommended
  for New Design) and is no longer supported in the STM32CubeWBA from version 1.1.0 (July 2023).
  The migration to :zephyr:board:`nucleo_wba55cg` (``nucleo_wba55cg``) is recommended instead.

* Updated Mbed TLS to version 3.6.4 (from 3.6.2). Release notes for 3.6.3 and
  3.6.4 can be found below:

  * 3.6.3: https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-3.6.3
  * 3.6.4: https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-3.6.4

* Updated TF-M to version 2.2.0 (from 2.1.1). The release notes can be found at:
  https://trustedfirmware-m.readthedocs.io/en/latest/releases/2.2.0.html

* Updated all boards with an external I2C connectors (Qwiic, Stemma, Grove...)
  to use the ``zephyr_i2c`` devicetree label. This allows using the existing
  :ref:`shields` build system feature (``west build --shield``) to interface
  any connectorized i2c module to any board with a compatible i2c port,
  regardless of the specific i2c connector branding.

* Reverted deprecation of receiver option in Nordic UART driver. Receiver mode which is using
  additional TIMER peripheral to count received bytes was previously deprecated
  (e.g. :kconfig:option:`CONFIG_CONFIG_UART_0_NRF_HW_ASYNC`). However, it turned out that this
  previously mode is the only one that is capable of reliably receive data without Hardware
  Flow Control so it should stay in the driver.
