+Migration guide to Zephyr v4.2.0 (Working Draft)
+################################################
+
+This document describes the changes required when migrating your application from Zephyr v4.1.0 to
+Zephyr v4.2.0.
+
+Any other changes (not directly related to migrating applications) can be found in
+the :ref:`release notes<zephyr_4.2>`.

+Kernel
+******
+
+Boards
+******
+
+* All boards based on Nordic ICs that used the ``nrfjprog`` Nordic command-line
+  tool for flashing by default have been modified to instead default to the new
+  nRF Util (``nrfutil``) tool. This means that you may need to `install nRF Util
+  <https://www.nordicsemi.com/Products/Development-tools/nrf-util>`_ or, if you
+  prefer to continue using ``nrfjprog``, you can do so by invoking west while
+  specfying the runner: ``west flash -r nrfjprog``. The full documentation for
+  nRF Util can be found
+  `here <https://docs.nordicsemi.com/bundle/nrfutil/page/README.html>`_.
+
+* All boards based on a Nordic IC of the nRF54L series now default to not
+  erasing any part of the internal storage when flashing. If you'd like to
+  revert to the previous default of erasing the pages that will be written to by
+  the firmware to be flashed you can use the new ``--erase-pages`` command-line
+  switch when invoking ``west flash``.
+  Note that RRAM on nRF54L devices is not physically paged, and paging is
+  only artificially provided, with a page size of 4096 bytes, for an easier
+  transition of nRF52 software to nRF54L devices.
+
+* The config option :kconfig:option:`CONFIG_NATIVE_POSIX_SLOWDOWN_TO_REAL_TIME` has been deprecated
+  in favor of :kconfig:option:`CONFIG_NATIVE_SIM_SLOWDOWN_TO_REAL_TIME`.
+
+* The DT binding :dtcompatible:`zephyr,native-posix-cpu` has been deprecated in favor of
+  :dtcompatible:`zephyr,native-sim-cpu`.
+
+* Zephyr now supports version 1.11.2 of the :zephyr:board:`neorv32`. NEORV32 processor (SoC)
+  implementations need to be updated to this version to be compatible with Zephyr v4.2.0.
+
+* The :zephyr:board:`neorv32` now targets NEORV32 processor (SoC) templates via board variants. The
+  old ``neorv32`` board target is now named ``neorv32/neorv32/up5kdemo``.
+
+* ``arduino_uno_r4_minima``, ``arduino_uno_r4_wifi``, and ``mikroe_clicker_ra4m1`` have migrated to
+  new FSP-based configurations.
+  While there are no major functional changes, the device tree structure has been significantly revised.
+  The following device tree bindings are now removed:
+  ``renesas,ra-gpio``, ``renesas,ra-uart-sci``, ``renesas,ra-pinctrl``,
+  ``renesas,ra-clock-generation-circuit``, and ``renesas,ra-interrupt-controller-unit``.
+  Instead, use the following replacements:
+  - :dtcompatible:`renesas,ra-gpio-ioport`
+  - :dtcompatible:`renesas,ra-sci-uart`
+  - :dtcompatible:`renesas,ra-pinctrl-pfs`
+  - :dtcompatible:`renesas,ra-cgc-pclk-block`
+
+* Nucleo WBA52CG board (``nucleo_wba52cg``) is not supported anymore since it is NRND
+  (Not Recommended for New Design) and it is not supported anymore in the STM32CubeWBA from
+  version 1.1.0 (July 2023). The migration to :zephyr:board:`nucleo_wba55cg` (``nucleo_wba55cg``)
+  is recommended and it could be done without any change.
+
+Device Drivers and Devicetree
+*****************************
+
+DAI
+===
+
+* Renamed the devicetree property ``dai_id`` to ``dai-id``.
+* Renamed the devicetree property ``afe_name`` to ``afe-name``.
+* Renamed the devicetree property ``agent_disable`` to ``agent-disable``.
+* Renamed the devicetree property ``ch_num`` to ``ch-num``.
+* Renamed the devicetree property ``mono_invert`` to ``mono-invert``.
+* Renamed the devicetree property ``quad_ch`` to ``quad-ch``.
+* Renamed the devicetree property ``int_odd`` to ``int-odd``.
+
+DMA
+===
+
+* Renamed the devicetree property ``nxp,a_on`` to ``nxp,a-on``.
+* Renamed the devicetree property ``dma_channels`` to ``dma-channels``.
+
+Counter
+=======
+
+* ``counter_native_posix`` has been renamed ``counter_native_sim``, and with it its
+  kconfig options and DT binding. :dtcompatible:`zephyr,native-posix-counter`  has been deprecated
+  in favor of :dtcompatible:`zephyr,native-sim-counter`.
+  And :kconfig:option:`CONFIG_COUNTER_NATIVE_POSIX` and its related options with
+  :kconfig:option:`CONFIG_COUNTER_NATIVE_SIM` (:github:`86616`).
+
+Entropy
+=======
+
+* ``fake_entropy_native_posix`` has been renamed ``fake_entropy_native_sim``, and with it its
+  kconfig options and DT binding. :dtcompatible:`zephyr,native-posix-rng`  has been deprecated
+  in favor of :dtcompatible:`zephyr,native-sim-rng`.
+  And :kconfig:option:`CONFIG_FAKE_ENTROPY_NATIVE_POSIX` and its related options with
+  :kconfig:option:`CONFIG_FAKE_ENTROPY_NATIVE_SIM` (:github:`86615`).
+
+Ethernet
+========
+
+* Removed Kconfig option ``ETH_STM32_HAL_MII`` (:github:`86074`).
+  PHY interface type is now selected via the ``phy-connection-type`` property in the device tree.
+
+* The :dtcompatible:`st,stm32-ethernet` driver now requires the ``phy-handle`` phandle to be
+  set to the according PHY node in the device tree (:github:`87593`).
+
+* The Kconfig options ``ETH_STM32_HAL_PHY_ADDRESS``, ``ETH_STM32_CARRIER_CHECK``,
+  ``ETH_STM32_CARRIER_CHECK_RX_IDLE_TIMEOUT_MS``, ``ETH_STM32_AUTO_NEGOTIATION_ENABLE``,
+  ``ETH_STM32_SPEED_10M``, ``ETH_STM32_MODE_HALFDUPLEX`` have been removed, as they are no longer
+  needed, and the driver now uses the ethernet phy api to communicate with the phy driver, which
+  is resposible for configuring the phy settings (:github:`87593`).
+
+* ``ethernet_native_posix`` has been renamed ``ethernet_native_tap``, and with it its
+  kconfig options: :kconfig:option:`CONFIG_ETH_NATIVE_POSIX` and its related options have been
+  deprecated in favor of :kconfig:option:`CONFIG_ETH_NATIVE_TAP` (:github:`86578`).
+
+Enhanced Serial Peripheral Interface (eSPI)
+===========================================
+
+* Renamed the devicetree property ``io_girq`` to ``io-girq``.
+* Renamed the devicetree property ``vw_girqs`` to ``vw-girqs``.
+* Renamed the devicetree property ``pc_girq`` to ``pc-girq``.
+* Renamed the devicetree property ``poll_timeout`` to ``poll-timeout``.
+* Renamed the devicetree property ``poll_interval`` to ``poll-interval``.
+* Renamed the devicetree property ``consec_rd_timeout`` to ``consec-rd-timeout``.
+* Renamed the devicetree property ``sus_chk_delay`` to ``sus-chk-delay``.
+* Renamed the devicetree property ``sus_rsm_interval`` to ``sus-rsm-interval``.
+
+GPIO
+====
+
+* To support the RP2350B, which has many pins, the Raspberry Pi-GPIO configuration has
+  been changed. The previous role of :dtcompatible:`raspberrypi,rpi-gpio` has been migrated to
+  :dtcompatible:`raspberrypi,rpi-gpio-port`, and :dtcompatible:`raspberrypi,rpi-gpio` is
+  now left as a placeholder and mapper.
+  The labels have also been changed along, so no changes are necessary for regular use.
+
+Sensors
+=======
+
+* ``ltr`` vendor prefix has been renamed to ``liteon``, and with it the
+  :dtcompatible:`ltr,f216a` name has been replaced by :dtcompatible:`liteon,ltrf216a`.
+  The choice :kconfig:option:`DT_HAS_LTR_F216A_ENABLED` has been replaced with
+  :kconfig:option:`DT_HAS_LITEON_LTRF216A_ENABLED` (:github:`85453`)
+
+Serial
+=======
+
+* ``uart_native_posix`` has been renamed ``uart_native_pty``, and with it its
+  kconfig options and DT binding. :dtcompatible:`zephyr,native-posix-uart`  has been deprecated
+  in favor of :dtcompatible:`zephyr,native-pty-uart`.
+  :kconfig:option:`CONFIG_UART_NATIVE_POSIX` and its related options with
+  :kconfig:option:`CONFIG_UART_NATIVE_PTY`.
+  The choice :kconfig:option:`CONFIG_NATIVE_UART_0` has been replaced with
+  :kconfig:option:`CONFIG_UART_NATIVE_PTY_0`, but now, it is also possible to select if a UART is
+  connected to the process stdin/out instead of a PTY at runtime with the command line option
+  ``--<uart_name>_stdinout``.
+  :kconfig:option:`CONFIG_NATIVE_UART_AUTOATTACH_DEFAULT_CMD` has been replaced with
+  :kconfig:option:`CONFIG_UART_NATIVE_PTY_AUTOATTACH_DEFAULT_CMD`.
+  :kconfig:option:`CONFIG_UART_NATIVE_WAIT_PTS_READY_ENABLE` has been deprecated. The functionality
+  it enabled is now always enabled as there is no drawbacks from it.
+  :kconfig:option:`CONFIG_UART_NATIVE_POSIX_PORT_1_ENABLE` has been deprecated. This option does
+  nothing now. Instead users should instantiate as many :dtcompatible:`zephyr,native-pty-uart` nodes
+  as native PTY UART instances they want. (:github:`86739`)
+
+Timer
+=====
+
+* ``native_posix_timer`` has been renamed ``native_sim_timer``, and so its kconfig option
+  :kconfig:option:`CONFIG_NATIVE_POSIX_TIMER` has been deprecated in favor of
+  :kconfig:option:`CONFIG_NATIVE_SIM_TIMER`, (:github:`86612`).
+
+Modem
+=====
+
+* Removed Kconfig option :kconfig:option:`CONFIG_MODEM_CELLULAR_CMUX_MAX_FRAME_SIZE` in favor of
+  :kconfig:option:`CONFIG_MODEM_CMUX_WORK_BUFFER_SIZE` and :kconfig:option:`CONFIG_MODEM_CMUX_MTU`.
+
+
+Stepper
+=======
+
+* Refactored the ``stepper_enable(const struct device * dev, bool enable)`` function to
+  :c:func:`stepper_enable` & :c:func:`stepper_disable`.
+
+Bluetooth
+*********
+
+Bluetooth Audio
+===============
+
+* ``CONFIG_BT_CSIP_SET_MEMBER_NOTIFIABLE`` has been renamed to
+  :kconfig:option:`CONFIG_BT_CSIP_SET_MEMBER_SIRK_NOTIFIABLE``. (:github:`86763``)
+
+Bluetooth Host
+==============
+
+* The symbols ``BT_LE_CS_TONE_ANTENNA_CONFIGURATION_INDEX_<NUMBER>`` in
+  :zephyr_file:`include/zephyr/bluetooth/conn.h` have been renamed
+  to ``BT_LE_CS_TONE_ANTENNA_CONFIGURATION_A<NUMBER>_B<NUMBER>``.
+
+* The ISO data paths are not longer setup automatically, and shall explicitly be setup and removed
+  by the application by calling :c:func:`bt_iso_setup_data_path` and
+  :c:func:`bt_iso_remove_data_path` respectively. (:github:`75549`)
+
+* ``BT_ISO_CHAN_TYPE_CONNECTED`` has been split into ``BT_ISO_CHAN_TYPE_CENTRAL`` and
+  ``BT_ISO_CHAN_TYPE_PERIPHERAL`` to better describe the type of the ISO channel, as behavior for
+  each role may be different. Any existing uses/checks for ``BT_ISO_CHAN_TYPE_CONNECTED``
+  can be replaced with an ``||`` of the two. (:github:`75549`)
+
+Bluetooth Classic
+=================
+
+* The parameters of HFP AG callback ``sco_disconnected`` of the struct :c:struct:`bt_hfp_ag_cb`
+  have been changed to SCO connection object ``struct bt_conn *sco_conn`` and the disconnection
+  reason of the SCO connection ``uint8_t reason``.
+
+Networking
+**********
+
+* The struct ``net_linkaddr_storage`` has been renamed to struct
+  :c:struct:`net_linkaddr` and the old struct ``net_linkaddr`` has been removed.
+  The struct :c:struct:`net_linkaddr` now contains space to store the link
+  address instead of having pointer that point to the link address. This avoids
+  possible dangling pointers when cloning struct :c:struct:`net_pkt`. This will
+  increase the size of struct :c:struct:`net_pkt` by 4 octets for IEEE 802.15.4,
+  but there is no size increase for other network technologies like Ethernet.
+  Note that any code that is using struct :c:struct:`net_linkaddr` directly, and
+  which has checks like ``if (lladdr->addr == NULL)``, will no longer work as expected
+  (because the addr is not a pointer) and must be changed to ``if (lladdr->len == 0)``
+  if the code wants to check that the link address is not set.
+
+* TLS credential type ``TLS_CREDENTIAL_SERVER_CERTIFICATE`` was renamed to
+  more generic :c:enumerator:`TLS_CREDENTIAL_PUBLIC_CERTIFICATE` to better
+  reflect the purpose of this credential type.
+
+* The MQTT public API function :c:func:`mqtt_disconnect` has changed. The function
+  now accepts additional ``param`` parameter to support MQTT 5.0 case. The parameter
+  is optional and not used with older MQTT versions - MQTT 3.1.1 users should pass
+  NULL as an argument.
+
+SPI
+===
+
+* Renamed the device tree property ``port_sel`` to ``port-sel``.
+* Renamed the device tree property ``chip_select`` to ``chip-select``.
