| * Fixed mcux to increase the PTP timestamp accuracy from 20us to 200ns. |
| * Fixed Ethernet max header size when using VLAN. |
| * Removed the ``mdio`` DT property. Please use :c:macro:`DT_INST_BUS()` in the driver instead. |
| * Reworked the device node hierarchy in smsc91x. |
| * Renamed the phy-dev property with phy-handle to match the Linux ethernet-controller binding |
| and move it up to ethernet.yaml so that it can be used by other drivers. |
| * Updated Ethernet PHY to use ``reg`` property in DT bindings. |
| * Updated driver DT bindings to use ``ethernet-phy`` devicetree node name consistently. |
| * Updated esp32 and sam-gmac DT so that the phy is pointed by a phandle rather than |
| a child node, this makes the phy device a child of mdio. |
| |
| * Flash |
| |
| * Introduce npcx flash driver that supports two or more spi nor flashes via a |
| single Flash Interface Unit (FIU) module and Direct Read Access (DRA) mode |
| for better performance. |

| * Fixed transfer issue when controller is busy. Now wait for controller to |
| idle before proceeding with another transfer. |
| |
| * IEEE 802.15.4 |
| |
| * A new mandatory method attr_get() was introduced into ieee802154_radio_api. |
| Drivers need to implement at least |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_PAGES and |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_RANGES. |
| * The hardware capabilities IEEE802154_HW_2_4_GHZ and IEEE802154_HW_SUB_GHZ |
| were removed as they were not aligned with the standard and some already |
| existing drivers couldn't properly express their channel page and channel |
| range (notably SUN FSK and HRP UWB drivers). The capabilities were replaced |
| by the standard conforming new driver attribute |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_PAGES that fits all in-tree drivers. |
| * The method get_subg_channel_count() was removed from ieee802154_radio_api. |
| This method could not properly express the channel range of existing drivers |
| (notably SUN FSK drivers that implement channel pages > 0 and may not have |
| zero-based channel ranges or UWB drivers that could not be represented at |
| all). The method was replaced by the new driver attribute |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_RANGES that fits all in-tree drivers. |

| Networking |
| ********** |
| |
| * CoAP: |
| |
| * Optimized CoAP client library to use only a single thread internally. |
| * Converted CoAP client library to use ``zsock_*`` API internally. |
| * Fixed a bug in CoAP client library, which resulted in an incorrect |
| retransmission timeout calculation. |
| * Use 64 bit timer values for calculating transmission timeouts. This fixes potential problems for |
| devices that stay on for more than 49 days when the 32 bit uptime counter might roll over and |
| cause CoAP packets to not timeout at all on this event. |
| * API documentation improvements. |
| * Added new API functions: |
| |
| * :c:func:`coap_has_descriptive_block_option` |
| * :c:func:`coap_remove_descriptive_block_option` |
| * :c:func:`coap_packet_remove_option` |
| * :c:func:`coap_packet_set_path` |
| |
| * Connection Manager: |
| |
| * Added support for auto-connect and auto-down behaviors (controlled by |
| :c:enum:`CONN_MGR_IF_NO_AUTO_CONNECT` and :c:enum:`CONN_MGR_IF_NO_AUTO_DOWN` |
| flags). |
| * Split Connection Manager APIs into separate header files. |
| * Extended Connection Manager documentation to cover new functionalities. |
| |
| * DHCP: |
| |
| * Added support for DHCPv4 unicast replies processing. |
| * Added support for DHCPv6 protocol. |
| |
| * Ethernet: |
| |
| * Fixed ARP queueing so that the queued network packet is sent immediately |
| instead of queued 2nd time in the core network stack. |
| |
| * gPTP: |
| |
| * Added support for detecting gPTP packets that use the default multicast destination address. |
| * Fixed Announce and Follow Up message handling. |
| |
| * ICMP: |
| |
| * Fixed ICMPv6 error message type check. |
| * Reworked ICMP callback registration and handling, which allows to register |
| multiple handlers for the same ICMP message. |
| * Introduced an API to send ICMP Echo Request (ping). |
| * Added possibility to register offloaded ICMP ping handlers. |
| * Added support for setting packet priority for ping. |
| |
| * IPv6: |
| |
| * Made sure that ongoing DAD procedure is cancelled when IPv6 address is removed. |
| * Fixed a bug, where Solicited-Node multicast address could be removed while |
| still in use. |
| |
| * LwM2M: |
| |
| * Added support for tickless mode. This removes the 500 ms timeout from the socket loop |
| so the engine does not constantly wake up the CPU. This can be enabled by |
| :kconfig:option:`CONFIG_LWM2M_TICKLESS`. |
| * Added new :c:macro:`LWM2M_RD_CLIENT_EVENT_DEREGISTER` event. |
| * Block-wise sending now supports LwM2M read and composite-read operations as well. |
| When :kconfig:option:`CONFIG_LWM2M_COAP_BLOCK_TRANSFER` is enabled, any content that is larger |
| than :kconfig:option:`CONFIG_LWM2M_COAP_MAX_MSG_SIZE` is split into a block-wise transfer. |
| * Block-wise transfers don't require tokens to match anymore as this was not in line |
| with CoAP specification (CoAP doesn't require tokens re-use). |
| * Various fixes to bootstrap. Now client ensures that Bootstrap-Finish command is sent, |
| before closing the DTLS pipe. Also allows Bootstrap server to close the DTLS pipe. |
| Added timeout when waiting for bootstrap commands. |
| * Added support for X509 certificates. |
| * Various fixes to string handling. Allow setting string to zero length. |
| Ensure string termination when using string operations on opaque resources. |
| * Added support for Connection Monitoring object version 1.3. |
| * Added protection for Security object to prevent read/writes by the server. |
| * Fixed a possible notification stall in case of observation token change. |
| * Added new shell command, ``lwm2m create``, which allows to create LwM2M object instances. |
| * Added LwM2M interoperability test-suite against Leshan server. |
| * API documentation improvements. |
| * Several other minor fixes and improvements. |
| |
| * Misc: |
| |
| * Time and timestamps in the network subsystem, PTP and IEEE 802.15.4 |
| were more precisely specified and all in-tree call sites updated accordingly. |
| Fields for timed TX and TX/RX timestamps have been consolidated. See |
| :c:type:`net_time_t`, :c:struct:`net_ptp_time`, :c:struct:`ieee802154_config`, |
| :c:struct:`ieee802154_radio_api` and :c:struct:`net_pkt` for extensive |
| documentation. As this is largely an internal API, existing applications will |
| most probably continue to work unchanged. |
| * Added support for additional net_pkt filter hooks: |
| |
| * :kconfig:option:`CONFIG_NET_PKT_FILTER_IPV4_HOOK` |
| * :kconfig:option:`CONFIG_NET_PKT_FILTER_IPV6_HOOK` |
| * :kconfig:option:`CONFIG_NET_PKT_FILTER_LOCAL_IN_HOOK` |
| |
| * Reworked several networking components to use timepoint API. |
| * Added API functions facilitate going through all IPv4/IPv6 registered on an |
| interface (:c:func:`net_if_ipv4_addr_foreach`, :c:func:`net_if_ipv6_addr_foreach`). |
| * ``NET_EVENT_IPV6_PREFIX_ADD`` and ``NET_EVENT_IPV6_PREFIX_DEL`` events now provide |
| more detailed information about the prefix (:c:struct:`net_event_ipv6_prefix`). |
| * General cleanup of the shadowed variables across the networking subsystem. |
| * Added ``qemu_cortex_a53`` networking support. |
| * Introduced new modem subsystem. |
| * Added new :zephyr:code-sample:`cellular-modem` sample. |
| * Added support for network interface names (instead of reusing underlying device name). |
| * Removed support for Google Cloud IoT sample due to service retirement. |
| * Fixed a bug where packets passed in promiscuous mode could have been modified |
| by L2 in certain cases. |
| * Added support for setting syslog server (used for networking log backend) |
| IP address at runtime. |
| * Removed no longer used ``queued`` and ``sent`` net_pkt flags. |
| * Added support for binding zperf TCP/UDP server to a specific IP address. |
| |
| * MQTT-SN: |
| |
| * Improved thread safety of internal buffers allocation. |
| * API documentation improvements. |
| |
| * OpenThread: |
| |
| * Reworked :c:func:`otPlatEntropyGet` to use :c:func:`sys_csrand_get` internally. |
| * Introduced ``ieee802154_radio_openthread.h`` radio driver extension interface |
| specific for OpenThread. Added new transmit mode, specific to OpenThread, |
| :c:enum:`IEEE802154_OPENTHREAD_TX_MODE_TXTIME_MULTIPLE_CCA`. |
| |
| * PPP: |
| |
| * Fixed PPP L2 usage of the network interface carrier state. |
| * Made PPP L2 thread priority configurable (:kconfig:option:`CONFIG_NET_L2_PPP_THREAD_PRIO`). |
| * Moved PPP L2 out of experimental stage. |
| * Prevent PPP connection reestablish when carrier is down. |
| |
| * Sockets: |
| |
| * Added support for statically allocated socketpairs (in case no heap is available). |
| * Made send timeout configurable (:kconfig:option:`CONFIG_NET_SOCKET_MAX_SEND_WAIT`). |
| * Added support for ``FIONREAD`` and ``FIONBIO`` :c:func:`ioctl` commands. |
| * Fixed input filtering for connected datagram sockets. |
| * Fixed :c:func:`getsockname` operation on unconnected sockets. |
| * Added new secure socket options for DTLS Connection ID support: |
| |
| * :c:macro:`TLS_DTLS_CID` |
| * :c:macro:`TLS_DTLS_CID_VALUE` |
| * :c:macro:`TLS_DTLS_PEER_CID_VALUE` |
| * :c:macro:`TLS_DTLS_CID_STATUS` |
| |
| * Added support for :c:macro:`SO_REUSEADDR` and :c:macro:`SO_REUSEPORT` socket options. |
| |
| * TCP: |
| |
| * Fixed potential stall in data retransmission, when data was only partially acknowledged. |
| * Made TCP work queue priority configurable (:kconfig:option:`CONFIG_NET_TCP_WORKER_PRIO`). |
| * Added support for TCP new Reno collision avoidance algorithm. |
| * Fixed source address selection on bound sockets. |
| * Fixed possible memory leak in case listening socket was closed during active handshake. |
| * Fixed RST packet handling during handshake. |
| * Refactored the code responsible for connection teardown to fix found bugs and |
| simplify future maintenance. |
| |
| * TFTP: |
| |
| * Added new :zephyr:code-sample:`tftp-client` sample. |
| * API documentation improvements. |
| |
| * WebSocket |
| |
| * WebSocket library no longer closes underlying TCP socket automatically on disconnect. |
| This aligns with the connect behavior, where the WebSocket library expects an already |
| connected TCP socket. |
| |
| * Wi-Fi: |
| |
| * Added Passive scan support. |
| * The Wi-Fi scan API updated with Wi-Fi scan parameter to allow scan mode selection. |
| * Updated TWT handling. |
| * Added support for generic network manager API. |
| * Added support for Wi-Fi mode setting and selection. |
| * Added user input validation for SSID and PSK in Wi-Fi shell. |
| * Added scan extension for specifying channels, limiting scan results, filtering SSIDs, |
| setting active and passive channel dwell times and frequency bands. |
| |
| USB |
| *** |
| |
| * USB device HID |
| * Kconfig option USB_HID_PROTOCOL_CODE, deprecated in v2.6, is finally removed. |

| Libraries / Subsystems |
| ********************** |
| |
| * Management |
| |
| * Introduced MCUmgr client support with handlers for img_mgmt and os_mgmt. |
| |
| * Added response checking to MCUmgr's :c:enumerator:`MGMT_EVT_OP_CMD_RECV` |
| notification callback to allow applications to reject MCUmgr commands. |
| |
| * MCUmgr SMP version 2 error translation (to legacy MCUmgr error code) is now |
| supported in function handlers by setting ``mg_translate_error`` of |
| :c:struct:`mgmt_group` when registering a group. See |
| :c:type:`smp_translate_error_fn` for function details. |
| |
| * Fixed an issue with MCUmgr img_mgmt group whereby the size of the upload in |
| the initial packet was not checked. |
| |
| * Fixed an issue with MCUmgr fs_mgmt group whereby some status codes were not |
| checked properly, this meant that the error returned might not be the |
| correct error, but would only occur in situations where an error was |
| already present. |
| |
| * Fixed an issue whereby the SMP response function did not check to see if |
| the initial zcbor map was created successfully. |
| |
| * Fixes an issue with MCUmgr shell_mgmt group whereby the length of a |
| received command was not properly checked. |
| |
| * Added optional mutex locking support to MCUmgr img_mgmt group, which can |
| be enabled with :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_MUTEX`. |
| |
| * Added MCUmgr settings management group, which allows for manipulation of |
| zephyr settings from a remote device, see :ref:`mcumgr_smp_group_3` for |
| details. |
| |
| * Added :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_CONFIRM_NON_ACTIVE_IMAGE_SECONDARY` |
| and :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_CONFIRM_NON_ACTIVE_IMAGE_ANY` |
| that allow to control whether MCUmgr client will be allowed to confirm |
| non-active images. |
| |
| * Added :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_ERASE_PENDING` that allows |
| to erase slots pending for next boot, that are not revert slots. |
| |
| * Added ``user_data`` as an optional field to :c:struct:`mgmt_handler` when |
| :kconfig:option:`CONFIG_MCUMGR_MGMT_HANDLER_USER_DATA` is enabled. |
| |
| * Added optional ``force`` parameter to os mgmt reset command, this can be checked in the |
| :c:enum:`MGMT_EVT_OP_OS_MGMT_RESET` notification callback whose data structure is |
| :c:struct:`os_mgmt_reset_data`. |
| |
| * Added configurable number of SMP encoding levels via |
| :kconfig:option:`CONFIG_MCUMGR_SMP_CBOR_MIN_ENCODING_LEVELS`, which automatically increments |
| minimum encoding levels for in-tree groups if :kconfig:option:`CONFIG_ZCBOR_CANONICAL` is |
| enabled. |
| |
| * Added STM32 SPI backend for EC Host command protocol. |
| |
| * Fixed settings_mgmt returning unknown error instead of invalid key specified error. |
| |

| * File systems |
| |
| * Added support for ext2 file system. |
| * Added support of mounting littlefs on the block device from the shell/fs. |
| * Added alignment parameter to FS_LITTLEFS_DECLARE_CUSTOM_CONFIG macro, it can speed up read/write |
| operation for SDMMC devices in case when we align buffers on CONFIG_SDHC_BUFFER_ALIGNMENT, |
| because we can avoid extra copy of data from card bffer to read/prog buffer. |
| |
| * Random |
| |
| * ``CONFIG_XOROSHIRO_RANDOM_GENERATOR``, deprecated a long time ago, is finally removed. |
| |
| * Retention |
| |
| * Added the :ref:`blinfo_api` subsystem. |
| |
| * Added support for allowing mutex support to be forcibly disabled with |
| :kconfig:option:`CONFIG_RETENTION_MUTEX_FORCE_DISABLE`. |
| |
| * Binary descriptors |
| |
| * Added the :ref:`binary_descriptors` (``bindesc``) subsystem. |
| |

| |
| HALs |
| **** |
| |
| * Nuvoton |
| |
| * Added Nuvoton NuMaker M46x |
| |
| MCUboot |
| ******* |
| |
| * Added :kconfig:option:`CONFIG_MCUBOOT_BOOTLOADER_NO_DOWNGRADE` |
| that allows to inform application that the on-board MCUboot has been configured |
| with downgrade prevention enabled. This option is automatically selected for |
| DirectXIP mode and is available for both swap modes. |
| |
| * Added :kconfig:option:`CONFIG_MCUBOOT_BOOTLOADER_MODE_OVERWRITE_ONLY` |
| that allows to inform application that the on-board MCUboot will overwrite |
| the primary slot with secondary slot contents, without saving the original |
| image in primary slot. |
| |
| * Fixed issue with serial recovery not showing image details for decrypted images. |
| |
| * Fixed issue with serial recovery in single slot mode wrongly iterating over 2 image slots. |
| |
| * Fixed an issue with boot_serial repeats not being processed when output was sent, this would |
| lead to a divergence of commands whereby later commands being sent would have the previous |
| command output sent instead. |
| |
| * Fixed an issue with the boot_serial zcbor setup encoder function wrongly including the buffer |
| address in the size which caused serial recovery to fail on some platforms. |
| |
| * Fixed wrongly building in optimize for debug mode by default, this saves a significant amount |
| of flash space. |
| |
| * Fixed issue with serial recovery use of MBEDTLS having undefined operations which led to usage |
| faults when the secondary slot image was encrypted. |
| |
| * Fixed issue with bootutil asserting on maximum alignment in non-swap modes. |
| |
| * Added error output when flash device fails to open and asserts are disabled, which will now |
| panic the bootloader. |
| |
| * Added currently running slot ID and maximum application size to shared data function |
| definition. |
| |
| * Added P384 and SHA384 support to imgtool. |
| |
| * Added optional serial recovery image state and image set state commands. |
| |
| * Added ``dumpinfo`` command for signed image parsing in imgtool. |
| |
| * Added ``getpubhash`` command to dump the sha256 hash of the public key in imgtool. |
| |
| * Added support for ``getpub`` to print the output to a file in imgtool. |
| |
| * Added support for dumping the raw versions of the public keys in imgtool. |
| |
| * Added support for sharing boot information with application via retention subsystem. |
| |
| * Added support for serial recovery to read and handle encrypted seondary slot partitions. |
| |
| * Removed ECDSA P224 support. |
| |
| * Removed custom image list boot serial extension support. |
| |
| * Reworked boot serial extensions so that they can be used by modules or from user repositories |
| by switching to iterable sections. |
| |
| * Reworked image encryption support for Zephyr, static dummy key files are no longer in the code, |
| a pem file must be supplied to extract the private and public keys. The Kconfig menu has |
| changed to only show a single option for enabling encryption and selecting the key file. |
| |
| * Reworked the ECDSA256 TLV curve agnostic and renamed it to ``ECDSA_SIG``. |
| |
| * CDDL auto-generated function code has been replaced with zcbor function calls, this now allows |
| the parameters to be supplied in any order. |
| |
| * The MCUboot version in this release is version ``2.0.0+0-rc1``. |
| |
| Nanopb |
| ****** |
| |
| * Changed project status to maintained. |
| |
| * Added a separate nanopb.cmake file to be included by applications. |
| |
| * Added helper cmake function ``zephyr_nanopb_sources`` to simplify ``.proto`` file inclusion. |
| |
| LVGL |
| **** |
| |
| * Changed project status to maintained. |
| |
| * Library has been updated to release v8.3.7. |
| |
| * Added ``zephyr,lvgl-{pointer,button,encoder}-input`` pseudo device bindings. |
| :kconfig:option:`CONFIG_LV_Z_KSCAN_POINTER` is still supported but touch controllers |
| need a :dtcompatible:`zephyr,kscan-input` child node to emit input events. |
| |
| * LVGL shell allows for monkey testing (requires :kconfig:option:`CONFIG_LV_USE_MONKEY`) |
| and inspecting memory usage. |
