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

* Removed SETTINGS_USE_BASE64 support as its been deprecated for more than
  two releases.

* The :c:func:`lwm2m_rd_client_start` function now accepts an additional
  ``flags`` parameter, which allows to configure current LwM2M client session,
  for instance enable bootstrap procedure in the current session.

* LwM2M execute now supports arguments. The execute callback
  :c:type:`lwm2m_engine_execute_cb_t` is extended with an ``args`` parameter
  which points to the CoAP payload that comprises the arguments, and an
  ``args_len`` parameter to indicate the length of the ``args`` data.

* Changed vcnl4040 dts binding default for property 'proximity-trigger'.
  Changed the default to match the HW POR state for this property.

* The :c:func:`clock_control_async_on` function will now take ``callback`` and
  ``user_data`` as arguments instead of structure which contained list node,
  callback and user data.

* The :c:func:`mqtt_keepalive_time_left` function now returns -1 if keep alive
  messages are disabled by setting ``CONFIG_MQTT_KEEPALIVE`` to 0.

* The ``CONFIG_LEGACY_TIMEOUT_API`` mode has been removed.  All kernel
  timeout usage must use the new-style k_timeout_t type and not the
  legacy/deprecated millisecond counts.

* The :c:func:`coap_pending_init` function now accepts an additional ``retries``
  parameter, allowing to specify the maximum retransmission count of the
  confirmable message.

* The ``CONFIG_BT_CTLR_CODED_PHY`` is now disabled by default for builds
  combining both Bluetooth host and controller.

* The :c:func:`coap_packet_append_payload` function will now take a pointer to a
  constant buffer as the ``payload`` argument instead of a pointer to a writable
  buffer.

* The :c:func:`coap_packet_init` function will now take a pointer to a constant
  buffer as the ``token`` argument instead of a pointer to a writable buffer.

* A new :ref:`regulator_api` API has been added to support controlling power
  sources.  Regulators can also be associated with devicetree nodes, allowing
  drivers to ensure the device they access has been powered up.  For simple
  GPIO-only regulators a devicetree property ``supply-gpios`` is defined as a
  standard way to identify the control signal in nodes that support power
  control.

* :c:type:`fs_tile_t` objects must now be initialized by calling
  :c:func:`fs_file_t_init` before their first use.

* :c:type:`fs_dir_t` objects must now be initialized by calling
  :c:func:`fs_dir_t_init` before their first use.

Deprecated in this release
==========================

* Nordic nRF5340 PDK board deprecated and planned to be removed in 2.6.0.
* ARM Musca-A board and SoC support deprecated and planned to be removed in 2.6.0.

* DEVICE_INIT was deprecated in favor of utilizing DEVICE_DEFINE directly.

* DEVICE_AND_API_INIT was deprecated in favor of DEVICE_DT_INST_DEFINE and
  DEVICE_DEFINE.

* Bluetooth

  * Deprecated the :c:func:`bt_set_id_addr` function, use :c:func:`bt_id_create`
    before calling :c:func:`bt_enable` instead. When ``CONFIG_PRIVACY`` is
    enabled a valid IRK has to be supplied by the application for this case.

Removed APIs in this release
============================

* Bluetooth

  * The deprecated BT_LE_SCAN_FILTER_DUPLICATE define has been removed,
    use BT_LE_SCAN_OPT_FILTER_DUPLICATE instead.
  * The deprecated BT_LE_SCAN_FILTER_WHITELIST define has been removed,
    use BT_LE_SCAN_OPT_FILTER_WHITELIST instead.
  * The deprecated bt_le_scan_param::filter_dup argument has been removed,
    use bt_le_scan_param::options instead.
  * The deprecated bt_conn_create_le() function has been removed,
    use bt_conn_le_create() instead.
  * The deprecated bt_conn_create_auto_le() function has been removed,
    use bt_conn_le_create_auto() instead.
  * The deprecated bt_conn_create_slave_le() function has been removed,
    use bt_le_adv_start() instead with bt_le_adv_param::peer set to the remote
    peers address.
  * The deprecated BT_LE_ADV_* macros have been removed,
    use the BT_GAP_ADV_* enums instead.
  * The deprecated bt_conn_security function has been removed,
    use bt_conn_set_security instead.
  * The deprecated BT_SECURITY_* defines NONE, LOW, MEDIUM, HIGH, FIPS have been
    removed, use the L0, L1, L2, L3, L4 defines instead.
  * The deprecated BT_HCI_ERR_AUTHENTICATION_FAIL define has been removed,
    use BT_HCI_ERR_AUTH_FAIL instead.

* Kernel

  * The deprecated k_mem_pool API has been removed entirely (for the
    past release it was backed by a k_heap, but maintained a
    compatible API).  Now all instantiated heaps must be
    sys_heap/k_heaps.  Note that the new-style heap is a general
    purpose allocator and does not make the same promises about block
    alignment/splitting.  Applications with such requirements should
    look at porting their logic, or perhaps at the k_mem_slab utility.

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

Kernel
******

* Added support for per thread runtime statistics
* Added new synchronization mechanisms using Condition Variables
* Thread Local Storage (TLS)

  * Introduced thread local storage support for the following architectures:

    * ARC
    * Arm Cortex-M
    * Arm Cortex-R
    * AArch64
    * RISC-V
    * Sparc
    * x86 and x86_64
    * Xtensa

  * This allows variables declared with ``__thread`` keyword to be allocated
    on a per-thread basis, and every thread has its own copy of these
    variables.
  * Enable via :kconfig:option:`CONFIG_THREAD_LOCAL_STORAGE`.
  * ``errno`` can be stored inside TLS if :kconfig:option:`CONFIG_ERRNO_IN_TLS`
    is enabled (together with :kconfig:option:`CONFIG_ERRNO`). This allow user
    threads to access the value of ``errno`` without making a system call.

* Memory Management

  * Added page frame management for physical memory to keep track of
    the status of each page frame.
  * Added :c:func:`k_mem_map` which allows applications to increase
    the data space available via anonymous memory mappings.
  * Added :c:func:`k_mem_free_get` which returns the amount of
    physical anonymous memory remaining.
  * Paging structure must now be pre-allocated so that there is no need
    to do memory allocations when mapping memory. Because of this,
    :c:func:`arch_mem_map` may no longer fail.

* Demand Paging

  * Introduced the framework for demand paging and infrastructure for
    custom eviction algorithms and implementation of backing stores.
  * Currently the whole kernel is pinned and remaining physical memory
    can be used for paging.

Architectures
*************

* ARC

  * Fixed execution on ARC HS with one interrupt bank and fast interrupts (FIRQ)
    enabled
  * Hardened SMP support
  * Improved mdb west runner to support simulation on SMP nSIM-based
    configurations
  * Improved mdb west runner to support nSIM-based configurations execution
    on real HW (FPGA-based)
  * Added documentation page with Zephyr support status on ARC processor
  * Added coverage support for nSIM-based configurations
  * Switched to upstream OpenOCD for ARC
  * Various minor fixes/improvements for ARC MWDT toolchain infrastructure

* ARM

  * AARCH32

    * Introduced the functionality for chain-loadable Zephyr
      firmware images to force the initialization of internal
      architecture state during early system boot (Cortex-M).
    * Changed the default Floating Point Services mode to
      Shared FP registers mode.
    * Enhanced Cortex-M Shared FP register mode by implementing
      dynamic lazy FP register stacking in threads.
    * Added preliminary support for Cortex-R7 variant.
    * Fixed inline assembly code in Cortex-M system calls.
    * Enhanced and fixed Cortex-M TCS support.
    * Enabled interrupts before switching to main in single-thread
      Cortex-M builds (CONFIG_MULTITHREADING=n).
    * Fixed vector table relocation in non-XIP Cortex-M builds.
    * Fixed exception exit routine for fatal error exceptions in
      Cortex-R.
    * Fixed interrupt nesting in ARMv7-R architecture.


  * AARCH64

    * Fixed registers printing on error and beautified crash dump output
    * Removed CONFIG_SWITCH_TO_EL1 symbol. By default the execution now drops
      to EL1 at boot
    * Deprecated booting from EL2
    * Improved assembly code and errors catching in EL3 and EL1 during the
      start routine
    * Enabled support for EL0 in the page tables
    * Fixed vector table alignment
    * Introduced support to boot Zephyr in NS mode
    * Fixed alignment fault in z_bss_zero
    * Added PSCI driver
    * Added ability to generate image header
    * Improved MMU code and driver

* RISC-V

  * Added support for PMP (Physical Memory Protection).
    Integrate PMP in Zephyr allow to support userspace (with shared
    memory) and stack guard features.

* SPARC

  * Added support for the SPARC architecture, compatible with the SPARC V8
    specification and the SPARC ABI.
  * FPU is supported in both shared and unshared FP register mode.

* x86

  * Enabled soft float support for Zephyr SDK
  * ``CONFIG_X86_MMU_PAGE_POOL_PAGES`` is removed as paging structure
    must now be pre-allocated.
  * Mapping of physical memory has changed:

    * This allows a smaller virtual address space thus requiring a smaller
      paging structure.
    * Only the kernel image is mapped when :kconfig:option:`CONFIG_ACPI` is not enabled.
    * When :kconfig:option:`CONFIG_ACPI` is enabled, the previous behavior to map
      all physical memory is retained as platforms with ACPI are usually not
      memory constrained and can accommodate bigger paging structure.

  * Page fault handler has been extended to support demand paging.

    should be using the new devicetree API introduced in Zephyr 2.3 and
    documented in :ref:`dt-from-c`. Information on flash partitions has moved
    to :ref:`flash_map_api`.
  * It is now possible to resolve at build time the device pointer associated
    with a device that is defined in devicetree, via ``DEVICE_DT_GET``.  See
    :ref:`dt-get-device`.
  * Enhanced support for enumerated property values via new macros:

    - :c:macro:`DT_ENUM_IDX_OR`
    - :c:macro:`DT_ENUM_TOKEN`
    - :c:macro:`DT_ENUM_UPPER_TOKEN`

  * New hardware specific macros:

    - :c:macro:`DT_GPIO_CTLR_BY_IDX`
    - :c:macro:`DT_GPIO_CTLR`
    - :c:macro:`DT_MTD_FROM_FIXED_PARTITION`

  * Miscellaneous new node-related macros:

    - :c:macro:`DT_GPARENT`
    - :c:macro:`DT_INVALID_NODE`
    - :c:macro:`DT_NODE_PATH`
    - :c:macro:`DT_SAME_NODE`

  * Property access macro changes:

    - :c:macro:`DT_PROP_BY_PHANDLE_IDX_OR`: new macro
    - :c:macro:`DT_PROP_HAS_IDX` now expands to a literal 0 or 1, not an
      expression that evaluates to 0 or 1

  * Dependencies between nodes are now exposed via new macros:

    - :c:macro:`DT_DEP_ORD`, :c:macro:`DT_INST_DEP_ORD`
    - :c:macro:`DT_REQUIRES_DEP_ORDS`, :c:macro:`DT_INST_REQUIRES_DEP_ORDS`
    - :c:macro:`DT_SUPPORTS_DEP_ORDS`, :c:macro:`DT_INST_SUPPORTS_DEP_ORDS`

* West

  * Improve bossac runner. It supports now native ROM bootloader for Atmel
    MCUs and extended SAM-BA bootloader like Arduino and Adafruit UF2. The
    devices supported depend on bossac version inside Zephyr SDK or in users
    path. The recommended Zephyr SDK version is 0.12.0 or newer.

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

* File systems

  * API

    * Added :c:func:`fs_file_t_init` function for initialization of
      :c:type:`fs_file_t` objects.

    * Added :c:func:`fs_dir_t_init` function for initialization of
      :c:type:`fs_dir_t` objects.

  * ``CONFIG_FS_LITTLEFS_FC_MEM_POOL`` has been deprecated and
    should be replaced by :kconfig:option:`CONFIG_FS_LITTLEFS_FC_HEAP_SIZE`.

* Management

  * MCUmgr

    * Added support for flash devices that have non-0xff erase value.
    * Added optional verification, enabled via
      :kconfig:option:`CONFIG_IMG_MGMT_REJECT_DIRECT_XIP_MISMATCHED_SLOT`, of an uploaded
      Direct-XIP binary, which will reject any binary that is not able to boot
      from base address of offered upload slot.

  * updatehub

    * Added support to Network Manager and interface overlays at UpdateHub
      sample. Ethernet is the default interface configuration and overlays
      can be used to change default configuration
    * Added WIFI overlay
    * Added MODEM overlay
    * Added IEEE 802.15.4 overlay [experimental]
    * Added BLE IPSP overlay as [experimental]
    * Added OpenThread overlay as [experimental].

* Settings

* Random

* POSIX subsystem

* Power management

  * Use a consistent naming convention using **pm_** namespace.
  * Overhaul power states. New states :c:enum:`pm_state` are more
    meaningful and ACPI alike.
  * Move residency information and supported power states to devicetree
    and remove related Kconfig options.
  * New power state changes notification API :c:struct:`pm_notifier`
  * Cleanup build options.

* LVGL

  * Library has been updated to minor release v7.6.1

* Storage

  * flash_map: Added API to get the value of an erased byte in the flash_area,
    see ``flash_area_erased_val()``.

* DFU

 * boot: Reworked using MCUBoot's bootutil_public library which allow to use
   API implementation already provided by MCUboot codebase and remove
   zephyr's own implementations.

* Crypto

  * mbedTLS updated to 2.16.9

HALs
****

* HALs are now moved out of the main tree as external modules and reside in
  their own standalone repositories.

MCUBoot
*******

* bootloader

  * Added hardening against hardware level fault injection and timing attacks,
    see ``CONFIG_BOOT_FIH_PROFILE_HIGH`` and similar kconfig options.
  * Introduced Abstract crypto primitives to simplify porting.
  * Added ram-load upgrade mode (not enabled for zephy-rtos yet).
  * Renamed single-image mode to single-slot mode,
    see ``CONFIG_SINGLE_APPLICATION_SLOT``.
  * Added patch for turning off cache for Cortex M7 before chain-loading.
  * Fixed bootstrapping in swap-move mode.
  * Fixed issue causing that interrupted swap-move operation might brick device
    if the primary image was padded.
  * Fixed issue causing that HW stack protection catches the chain-loaded
    application during its early initialization.
  * Added reset of Cortex SPLIM registers before boot.
  * Fixesd build issue that occurs if CONF_FILE contains multiple file paths
    instead of single file path.
  * Added watchdog feed on nRF devices. See ``CONFIG_BOOT_WATCHDOG_FEED`` option.
  * Removed the flash_area_read_is_empty() port implementation function.
  * Initialize the ARM core configuration only when selected by the user,
    see ``CONFIG_MCUBOOT_CLEANUP_ARM_CORE``.
  * Allow the final data chunk in the image to be unaligned in
    the serial-recovery protocol.
  * Kconfig: allow xip-revert only for xip-mode.
  * ext: tinycrypt: update ctr mode to stream.
  * Use minimal CBPRINTF implementation.
  * Configure logging to LOG_MINIMAL by default.
  * boot: cleanup NXP MPU configuration before boot.
  * Fix nokogiri<=1.11.0.rc4 vulnerability.
  * bootutil_public library was extracted as code which is common API for
    MCUboot and the DFU application, see ``CONFIG_MCUBOOT_BOOTUTIL_LIB``

* imgtool

  * Print image digest during verify.
  * Add possibility to set confirm flag for hex files as well.
  * Usage of --confirm implies --pad.
  * Fixed 'custom_tlvs' argument handling.
  * Add support for setting fixed ROM address into image header.
  * Fixed verification with protected TLVs.


Trusted-Firmware-M
******************

* Synchronized Trusted-Firmware-M module to the upstream v1.2.0 release.

Documentation
*************

Tests and Samples
*****************

  * A sample was added to demonstrate how to use the ADC driver API.
  * Sanitycheck script was renamed to twister
