  What goes here: removed/deprecated apis, new boards, new drivers, notable
  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
  actual project documentation rather than the release notes, so that the
  information does not get lost in time.
..
  No list of bugfixes, minor changes, those are already in the git log, this is
  not a changelog.
..
  Does the entry have a link that contains the details? Just add the link, if
  you think it needs more details, put them in the content that shows up on the
  link.
..
  Are you thinking about generating this? Don't put anything at all.

  Does the thing require the user to change their application? Put it on the
  migration guide instead. (TODO: move the removed APIs section in the
  migration guide)

.. _zephyr_4.3:

Zephyr 4.3.0
############

We are pleased to announce the release of Zephyr version 4.3.0.

Major enhancements with this release include:

**USB Device "Next" stack is now the default**
  The new :ref:`USB device stack <usb_device_stack_next>`, built on the modern UDC (USB Device
  Controller) API, replaces the legacy stack and brings support for multiple simultaneous
  controllers, runtime configuration, and overall better architecture.
  The legacy stack is now deprecated and will be removed in Zephyr 4.5.

**CPU load and dynamic frequency scaling subsystems**
  A new experimental :ref:`CPU frequency <cpu_freq>` scaling subsystem enables dynamic,
  policy-driven, clock adjustments to balance power consumption and performance.
  Alongside it, a new :ref:`cpu_load` subsystem allows users to obtain CPU usage metrics based on
  scheduler statistics, which can be used to drive the frequency scaling policy.

**Instrumentation Subsystem**
  A new :ref:`instrumentation subsystem <instrumentation>` simplifies tracing and profiling of
  Zephyr applications by leveraging compiler-managed function instrumentation, allowing the
  recording of call-graph traces and statistical profiles at runtime.

**OCPP 1.6 library**
  A new :ref:`OCPP (Open Charge Point Protocol) <ocpp_interface>` library enables EV charging
  station development with Zephyr. The library implements OCPP 1.6 Charge Point functionality
  over WebSocket, supporting core profile operations including authorization, transaction
  management, and meter value reporting for communication with Central System servers.

**Twister Display Harness**
  Twister can now :ref:`validate on-target display output <twister_display_capture_harness>` by
  capturing frames from a USB video camera and matching them against pre-recorded visual
  "fingerprints".

**Developer Experience Improvements**
  Several new tools have been introduced to help with common development and troubleshooting tasks:

  - :ref:`dtdoctor` to help diagnose Devicetree build errors.
  - :ref:`traceconfig <kconfig_traceconfig>` build target to help understand where Kconfig symbols
    come from and their final values.
  - :ref:`Interactive footprint charts <footprint_tools_plot>` to visualize RAM/ROM usage of an
    application.

**Expanded Board Support**
  Support for 105 :ref:`new boards <boards_added_in_zephyr_4_3>` and 39
  :ref:`new shields <shields_added_in_zephyr_4_3>` has been added in this release.

An overview of the changes required or recommended when migrating your application from Zephyr
v4.2.0 to Zephyr v4.3.0 can be found in the separate :ref:`migration guide<migration_4.3>`.

The following sections provide detailed lists of changes by component.

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

..
  Only removed, deprecated and new APIs, changes go in migration guide.

* Crypto

  * The input buffer in :c:struct:`hash_pkt` is now constant

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

* The TinyCrypt library was removed as the upstream version is no longer maintained.
  PSA Crypto API is now the recommended cryptographic library for Zephyr.
* The legacy pipe object API was removed. Use the new pipe API instead.
* ``bt_le_set_auto_conn``
* ``CONFIG_BT_BUF_ACL_RX_COUNT``
* ``ok`` enum value has now been removed completely from ``base.yaml`` binding ``status`` property in Devicetree.
* STM32 LPTIM clock source selection through Kconfig was removed. Devicetree must now be used instead.
  Affected Kconfig symbols: :kconfig:option:`CONFIG_STM32_LPTIM_CLOCK_LSI` / :kconfig:option:`CONFIG_STM32_LPTIM_CLOCK_LSE`

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

* :dtcompatible:`maxim,ds3231` is deprecated in favor of :dtcompatible:`maxim,ds3231-rtc`.
* Providing a third argument to :c:macro:`SPI_CONFIG_DT`, :c:macro:`SPI_CONFIG_DT_INST`,
  :c:macro:`SPI_DT_SPEC_GET`, :c:macro:`SPI_DT_SPEC_INST_GET` is deprecated. Providing a
  second argument to :c:macro:`SPI_CS_CONTROL_INIT` is deprecated. Use new DT properties
  ``spi-cs-setup-delay-ns`` and ``spi-cs-hold-delay-ns`` to specify delay instead.

* :c:enum:`bt_hci_bus` was deprecated as it was not used. :c:macro:`BT_DT_HCI_BUS_GET` should be
  used instead.

* :kconfig:option:`CONFIG_BT_AUTO_PHY_UPDATE` was deprecated and has been replaced with
  role-specific (central vs peripheral) options that allow specifying exactly which PHY is
  preferred for automatic updates.

* :kconfig:option:`CONFIG_POSIX_READER_WRITER_LOCKS` is deprecated. Use :kconfig:option:`CONFIG_POSIX_RW_LOCKS` instead.

* :kconfig:option:`CONFIG_JWT_SIGN_RSA_LEGACY` is deprecated. Please switch to the
  PSA Crypto API based alternative (i.e. :kconfig:option:`CONFIG_JWT_SIGN_RSA_PSA`).

* RISCV's :kconfig:option:`CONFIG_EXTRA_EXCEPTION_INFO` is deprecated. Use :kconfig:option:`CONFIG_EXCEPTION_DEBUG` instead.

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.

Libraries / Subsystems
**********************

* Firmware

  * SCMI

    * Added :kconfig:option:`ARM_SCMI_CHAN_SEM_TIMEOUT_USEC` to allow configuring the channel semaphore timeout.
    * Use :c:func:`scmi_status_to_errno` directly for checking the returned command status code.
    * Added new parameter to :c:func:`scmi_send_message` allowing users to specify if they want to use polling or not.
    * [NXP] Various additions related to the NXP-specific CPU protocol.

* Logging:

  * Added hybrid rate-limited logging macros to prevent log flooding when messages are generated frequently.
    The system provides both convenience macros (using default rate from :kconfig:option:`CONFIG_LOG_RATELIMIT_INTERVAL_MS`)
    and explicit rate macros (with custom rate parameter). This follows Linux's ``printk_ratelimited`` pattern
    while providing more flexibility. The rate limiting is per-macro-call-site, meaning that each unique call
    to a rate-limited macro has its own independent rate limit. Rate-limited logging can be globally enabled/disabled
    via :kconfig:option:`CONFIG_LOG_RATELIMIT`. When rate limiting is disabled, the behavior can be controlled
    via :kconfig:option:`CONFIG_LOG_RATELIMIT_FALLBACK` to either log all messages or drop them completely.
    For more details, see :ref:`logging_ratelimited`.

* Mbed TLS

  * Kconfig :kconfig:option:`CONFIG_PSA_CRYPTO` is added to simplify the enablement of a PSA
    Crypto API provider. This is TF-M if :kconfig:option:`CONFIG_BUILD_WITH_TFM` is enabled,
    or Mbed TLS otherwise. :kconfig:option:`CONFIG_PSA_CRYPTO_PROVIDER_TFM` is set in the former
    case while :kconfig:option:`CONFIG_PSA_CRYPTO_PROVIDER_MBEDTLS` is set in the latter.
    :kconfig:option:`CONFIG_PSA_CRYPTO_PROVIDER_CUSTOM` is also added to allow end users to
    provide a custom solution.

  * Updated from version 3.6.4 to version 3.6.5. Release notes for this release can be found at the
    following link:

    * https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-3.6.5

* Secure storage

  * The experimental status has been removed. (:github:`96483`)

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?

* Nordic Semiconductor nRF54L09 PDK (``nrf54l09pdk``), which only targeted an emulator, has been removed
  from the tree. It will be replaced with a proper board definition as soon as it's available.

* Removed support for Nordic Semiconductor nRF54L20 PDK (``nrf54l20pdk``) since it is
  replaced with :zephyr:board:`nrf54lm20dk` (``nrf54lm20dk``).
