The capabilities were replaced 589 by the standard conforming new driver attribute 590 IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_PAGES that fits all in-tree drivers. 591 * The method get_subg_channel_count() was removed from ieee802154_radio_api. 592 This method could not properly express the channel range of existing drivers 593 (notably SUN FSK drivers that implement channel pages > 0 and may not have 594 zero-based channel ranges or UWB drivers that could not be represented at 595 all). The method was replaced by the new driver attribute 596 IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_RANGES that fits all in-tree drivers. 597 598* Interrupt Controller 599 600 * GIC: Architecture version selection is now based on the device tree 601 602* Input 603 604 * New drivers: :dtcompatible:`gpio-qdec`, :dtcompatible:`st,stmpe811`. 605 606 * Drivers converted from Kscan to Input: :dtcompatible:`goodix,gt911` 607 :dtcompatible:`xptek,xpt2046` :dtcompatible:`hynitron,cst816s` 608 :dtcompatible:`microchip,cap1203`. 609 610 * Added a Kconfig option for dumping all events to the console 611 :kconfig:option:`CONFIG_INPUT_EVENT_DUMP` and new shell commands 612 :kconfig:option:`CONFIG_INPUT_SHELL`. 613 614 * Merged ``zephyr,gpio-keys`` into :dtcompatible:`gpio-keys` and added 615 ``zephyr,code`` codes to all in-tree board ``gpio-keys`` nodes. 616 617 * Renamed the callback definition macro from ``INPUT_LISTENER_CB_DEFINE`` to 618 :c:macro:`INPUT_CALLBACK_DEFINE`. 619 620* PCIE 621 622 * Added support in shell to display PCIe capabilities. 623 624 * Added virtual channel support. 625 626 * Added kconfig :kconfig:option:`CONFIG_PCIE_INIT_PRIORITY` to specify 627 initialization priority for host controller. 628 629 * Added support to get IRQ from ACPI PCI Routing Table (PRT). 630 631* ACPI 632 633 * Adopted the ACPICA library as a new module to further enhance ACPI support. 634 635* Pin control 636 637 * Added support for Nuvoton NuMaker M46x 638 639* PWM 640 641 * Added 4 channels capture on STM32 PWM driver. 642 * Added driver for Intel Blinky PWM. 643 * Added driver for MAX31790. 644 * Added driver for Infineon XMC4XXX CCU4. 645 * Added driver for Infineon XMC4XXX CCU8. 646 * Added MCUX CTimer based PWM driver. 647 * Added PWM driver based on TI CC13xx/CC26xx GPT timer. 648 * Reworked the pwm_nrf5_sw driver so that it can be used also on nRF53 and 649 nRF91 Series. Consequently, the driver was renamed to pwm_nrf_sw. 650 * Added driver for Nuvoton NuMaker family. 651 * Added PWM driver based on NXP S32 EMIOS peripheral. 652 653* Regulators 654 655 * Added support for GPIO-controlled voltage regulator 656 657 * Added support for AXP192 PMIC 658 659 * Added support for NXP VREF regulator 660 661 * Fixed regulators can now specify their operating voltage 662 663 * PFM mode is now support for nPM1300 664 665 * Added new API to configure "ship" mode 666 667 * Regulator shell allows to configure DVS modes 668 669* Reset 670 671 * Added support for Nuvoton NuMaker M46x 672 673* Retained memory 674 675 * Added support for allowing mutex support to be forcibly disabled with 676 :kconfig:option:`CONFIG_RETAINED_MEM_MUTEX_FORCE_DISABLE`. 677 678 * Fixed issue with user mode support not working. 679 680* RTC 681 682 * Added support for STM32 RTC API driver. This driver is not compatible with 683 the use of RTC based implementation of COUNTER API. 684 685* SDHC 686 687 * Added driver for EMMC Host controller present on Alder lake platforms 688 * Added driver for Atmel HSMCI controller present on SAM4E MCU series 689 690* Sensor 691 692 * Reworked the :dtcompatible:`ti,bq274xx` to add ``BQ27427`` support, fixed 693 units for capacity and power channels. 694 * Added ADC current sense amplifier and voltage sensor drivers. 695 * Added ADI LTC2990 voltage, current, and temperature sensor driver. 696 * Added AMS TSL2540 ambient light sensor driver. 697 * Added Bosch BMI08x accelerometer/gyroscope driver. 698 * Added DFRobot A01NYUB distance sensor driver. 699 * Added Fintek F75303 temperature sensor driver. 700 * Added Isentek IST8310 magnetometer driver. 701 * Added Microchip TCN75A temperature sensor driver. 702 * Added NXP TEMPMON driver. 703 * Added Seeed HM330X dust sensor driver. 704 * Added TI TMAG5170 3D Hall sensor driver. 705 * Added power management support to BMM150, LM75, and Microchip tachometer 706 drivers. 707 * Added trigger support to the BMM150 magnetometer driver. 708 * Added tap trigger support to the LIS2DH accelerometer driver. 709 * Updated ST sensor drivers to use STMEMSC HAL i/f v2.3 710 * Updated the decoder APIs to vertically decode raw sensor data. 711 * Various fixes and enhancements in the NTC thermistor and INA23x drivers. 712 713* Serial 714 715 * Added support for Nuvoton NuMaker M46x 716 717 * NS16550: Reworked how device initialization macros. 718 719 * ``CONFIG_UART_NS16550_ACCESS_IOPORT`` and ``CONFIG_UART_NS16550_SIMULT_ACCESS`` 720 are removed. For UART using IO port access, add ``io-mapped`` property to 721 device tree node. 722 723 * Added async support for ESP32S3. 724 725 * Added support for serial TTY under ``native_posix``. 726 727 * Added support for UART on Efinix Sapphire SoCs. 728 729 * Added Intel SEDI UART driver. 730 731 * Added support for UART on BCM2711. 732 733 * ``uart_stm32``: 734 735 * Added RS485 support. 736 737 * Added wide data support. 738 739 * ``uart_pl011``: added support for Ambiq SoCs. 740 741 * ``serial_test``: added support for interrupt and async APIs. 742 743 * ``uart_emul``: added support for interrupt API. 744 745 * ``uart_rpi_pico``: fixed handling Modbus DE-RE signal 746 747* SPI 748 749 * Remove npcx spi driver implemented by Flash Interface Unit (FIU) module. 750 * Added support for Raspberry Pi Pico PIO based SPI. 751 752* Timer 753 754 * The TI CC13xx/26xx system clock timer compatible was changed from 755 :dtcompatible:`ti,cc13xx-cc26xx-rtc` to :dtcompatible:`ti,cc13xx-cc26xx-rtc-timer` 756 and the corresponding Kconfig option from :kconfig:option:`CC13X2_CC26X2_RTC_TIMER` 757 to :kconfig:option:`CC13XX_CC26XX_RTC_TIMER` for improved consistency and 758 extensibility. No action is required unless the internal timer was modified. 759 760* USB 761 762 * Added UDC driver for STM32 based MCU, relying on HAL/PCD. This driver is compatible 763 with UDC API (experimental). 764 * Added support for STM32H5 series on USB driver. 765 766* WiFi 767 768 * Increased esp32 default network (TCP workq, RX and mgmt event) stack sizes to 2048 bytes. 769 * Reduced the RAM usage for esp32s2_saola in Wi-Fi samples. 770 * Fixed undefined declarations in winc1500. 771 * Fixed SPI buffer length in eswifi. 772 * Fixed esp32 data sending and channel selection in AP mode. 773 * Fixed esp_at driver init and network interface dormant state setting. 774 775Networking 776********** 777 778* CoAP: 779 780 * Optimized CoAP client library to use only a single thread internally. 781 * Converted CoAP client library to use ``zsock_*`` API internally. 782 * Fixed a bug in CoAP client library, which resulted in an incorrect 783 retransmission timeout calculation. 784 * Use 64 bit timer values for calculating transmission timeouts. This fixes potential problems for 785 devices that stay on for more than 49 days when the 32 bit uptime counter might roll over and 786 cause CoAP packets to not timeout at all on this event. 787 * API documentation improvements. 788 * Added new API functions: 789 790 * :c:func:`coap_has_descriptive_block_option` 791 * :c:func:`coap_remove_descriptive_block_option` 792 * :c:func:`coap_packet_remove_option` 793 * :c:func:`coap_packet_set_path` 794 795* Connection Manager: 796 797 * Added support for auto-connect and auto-down behaviors (controlled by 798 :c:enum:`CONN_MGR_IF_NO_AUTO_CONNECT` and :c:enum:`CONN_MGR_IF_NO_AUTO_DOWN` 799 flags). 800 * Split Connection Manager APIs into separate header files. 801 * Extended Connection Manager documentation to cover new functionalities. 802 803* DHCP: 804 805 * Added support for DHCPv4 unicast replies processing. 806 * Added support for DHCPv6 protocol. 807 808* Ethernet: 809 810 * Fixed ARP queueing so that the queued network packet is sent immediately 811 instead of queued 2nd time in the core network stack. 812 813* gPTP: 814 815 * Added support for detecting gPTP packets that use the default multicast destination address. 816 * Fixed Announce and Follow Up message handling. 817 818* ICMP: 819 820 * Fixed ICMPv6 error message type check. 821 * Reworked ICMP callback registration and handling, which allows to register 822 multiple handlers for the same ICMP message. 823 * Introduced an API to send ICMP Echo Request (ping). 824 * Added possibility to register offloaded ICMP ping handlers. 825 * Added support for setting packet priority for ping. 826 827* IPv6: 828 829 * Made sure that ongoing DAD procedure is cancelled when IPv6 address is removed. 830 * Fixed a bug, where Solicited-Node multicast address could be removed while 831 still in use. 832 833* LwM2M: 834 835 * Added support for tickless mode. This removes the 500 ms timeout from the socket loop 836 so the engine does not constantly wake up the CPU. This can be enabled by 837 :kconfig:option:`CONFIG_LWM2M_TICKLESS`. 838 * Added new :c:macro:`LWM2M_RD_CLIENT_EVENT_DEREGISTER` event. 839 * Block-wise sending now supports LwM2M read and composite-read operations as well. 840 When :kconfig:option:`CONFIG_LWM2M_COAP_BLOCK_TRANSFER` is enabled, any content that is larger 841 than :kconfig:option:`CONFIG_LWM2M_COAP_MAX_MSG_SIZE` is split into a block-wise transfer. 842 * Block-wise transfers don't require tokens to match anymore as this was not in line 843 with CoAP specification (CoAP doesn't require tokens reuse). 844 * Various fixes to bootstrap. Now client ensures that Bootstrap-Finish command is sent, 845 before closing the DTLS pipe. Also allows Bootstrap server to close the DTLS pipe. 846 Added timeout when waiting for bootstrap commands. 847 * Added support for X509 certificates. 848 * Various fixes to string handling. Allow setting string to zero length. 849 Ensure string termination when using string operations on opaque resources. 850 * Added support for Connection Monitoring object version 1.3. 851 * Added protection for Security object to prevent read/writes by the server. 852 * Fixed a possible notification stall in case of observation token change. 853 * Added new shell command, ``lwm2m create``, which allows to create LwM2M object instances. 854 * Added LwM2M interoperability test-suite against Leshan server. 855 * API documentation improvements. 856 * Several other minor fixes and improvements. 857 858* Misc: 859 860 * Time and timestamps in the network subsystem, PTP and IEEE 802.15.4 861 were more precisely specified and all in-tree call sites updated accordingly. 862 Fields for timed TX and TX/RX timestamps have been consolidated. See 863 :c:type:`net_time_t`, :c:struct:`net_ptp_time`, :c:struct:`ieee802154_config`, 864 :c:struct:`ieee802154_radio_api` and :c:struct:`net_pkt` for extensive 865 documentation. As this is largely an internal API, existing applications will 866 most probably continue to work unchanged. 867 * Added support for additional net_pkt filter hooks: 868 869 * :kconfig:option:`CONFIG_NET_PKT_FILTER_IPV4_HOOK` 870 * :kconfig:option:`CONFIG_NET_PKT_FILTER_IPV6_HOOK` 871 * :kconfig:option:`CONFIG_NET_PKT_FILTER_LOCAL_IN_HOOK` 872 873 * Reworked several networking components to use timepoint API. 874 * Added API functions facilitate going through all IPv4/IPv6 registered on an 875 interface (:c:func:`net_if_ipv4_addr_foreach`, :c:func:`net_if_ipv6_addr_foreach`). 876 * ``NET_EVENT_IPV6_PREFIX_ADD`` and ``NET_EVENT_IPV6_PREFIX_DEL`` events now provide 877 more detailed information about the prefix (:c:struct:`net_event_ipv6_prefix`). 878 * General cleanup of the shadowed variables across the networking subsystem. 879 * Added ``qemu_cortex_a53`` networking support. 880 * Introduced new modem subsystem. 881 * Added new :zephyr:code-sample:`cellular-modem` sample. 882 * Added support for network interface names (instead of reusing underlying device name). 883 * Removed support for Google Cloud IoT sample due to service retirement. 884 * Fixed a bug where packets passed in promiscuous mode could have been modified 885 by L2 in certain cases. 886 * Added support for setting syslog server (used for networking log backend) 887 IP address at runtime. 888 * Removed no longer used ``queued`` and ``sent`` net_pkt flags. 889 * Added support for binding zperf TCP/UDP server to a specific IP address. 890 891* MQTT-SN: 892 893 * Improved thread safety of internal buffers allocation. 894 * API documentation improvements. 895 896* OpenThread: 897 898 * Reworked :c:func:`otPlatEntropyGet` to use :c:func:`sys_csrand_get` internally. 899 * Introduced ``ieee802154_radio_openthread.h`` radio driver extension interface 900 specific for OpenThread. Added new transmit mode, specific to OpenThread, 901 :c:enum:`IEEE802154_OPENTHREAD_TX_MODE_TXTIME_MULTIPLE_CCA`. 902 903* PPP: 904 905 * Fixed PPP L2 usage of the network interface carrier state. 906 * Made PPP L2 thread priority configurable (:kconfig:option:`CONFIG_NET_L2_PPP_THREAD_PRIO`). 907 * Moved PPP L2 out of experimental stage. 908 * Prevent PPP connection reestablish when carrier is down. 909 910* Sockets: 911 912 * Added support for statically allocated socketpairs (in case no heap is available). 913 * Made send timeout configurable (:kconfig:option:`CONFIG_NET_SOCKET_MAX_SEND_WAIT`). 914 * Added support for ``FIONREAD`` and ``FIONBIO`` :c:func:`ioctl` commands. 915 * Fixed input filtering for connected datagram sockets. 916 * Fixed :c:func:`getsockname` operation on unconnected sockets. 917 * Added new secure socket options for DTLS Connection ID support: 918 919 * :c:macro:`TLS_DTLS_CID` 920 * :c:macro:`TLS_DTLS_CID_VALUE` 921 * :c:macro:`TLS_DTLS_PEER_CID_VALUE` 922 * :c:macro:`TLS_DTLS_CID_STATUS` 923 924 * Added support for :c:macro:`SO_REUSEADDR` and :c:macro:`SO_REUSEPORT` socket options. 925 926* TCP: 927 928 * Fixed potential stall in data retransmission, when data was only partially acknowledged. 929 * Made TCP work queue priority configurable (:kconfig:option:`CONFIG_NET_TCP_WORKER_PRIO`). 930 * Added support for TCP new Reno collision avoidance algorithm. 931 * Fixed source address selection on bound sockets. 932 * Fixed possible memory leak in case listening socket was closed during active handshake. 933 * Fixed RST packet handling during handshake. 934 * Refactored the code responsible for connection teardown to fix found bugs and 935 simplify future maintenance. 936 937* TFTP: 938 939 * Added new :zephyr:code-sample:`tftp-client` sample. 940 * API documentation improvements. 941 942* WebSocket 943 944 * WebSocket library no longer closes underlying TCP socket automatically on disconnect. 945 This aligns with the connect behavior, where the WebSocket library expects an already 946 connected TCP socket. 947 948* Wi-Fi: 949 950 * Added Passive scan support. 951 * The Wi-Fi scan API updated with Wi-Fi scan parameter to allow scan mode selection. 952 * Updated TWT handling. 953 * Added support for generic network manager API. 954 * Added support for Wi-Fi mode setting and selection. 955 * Added user input validation for SSID and PSK in Wi-Fi shell. 956 * Added scan extension for specifying channels, limiting scan results, filtering SSIDs, 957 setting active and passive channel dwell times and frequency bands. 958 959USB 960*** 961 962* USB device HID 963 * Kconfig option USB_HID_PROTOCOL_CODE, deprecated in v2.6, is finally removed. 964 965Devicetree 966********** 967 968API 969=== 970 971New general-purpose macros: 972 973- :c:macro:`DT_REG_ADDR_U64` 974- :c:macro:`DT_REG_ADDR_BY_NAME_U64` 975-

client support with handlers for img_mgmt and os_mgmt. 2055 2056 * Added response checking to MCUmgr's :c:enumerator:`MGMT_EVT_OP_CMD_RECV` 2057 notification callback to allow applications to reject MCUmgr commands. 2058 2059 * MCUmgr SMP version 2 error translation (to legacy MCUmgr error code) is now 2060 supported in function handlers by setting ``mg_translate_error`` of 2061 :c:struct:`mgmt_group` when registering a group. See 2062 :c:type:`smp_translate_error_fn` for function details. 2063 2064 * Fixed an issue with MCUmgr img_mgmt group whereby the size of the upload in 2065 the initial packet was not checked. 2066 2067 * Fixed an issue with MCUmgr fs_mgmt group whereby some status codes were not 2068 checked properly, this meant that the error returned might not be the 2069 correct error, but would only occur in situations where an error was 2070 already present. 2071 2072 * Fixed an issue whereby the SMP response function did not check to see if 2073 the initial zcbor map was created successfully. 2074 2075 * Fixes an issue with MCUmgr shell_mgmt group whereby the length of a 2076 received command was not properly checked. 2077 2078 * Added optional mutex locking support to MCUmgr img_mgmt group, which can 2079 be enabled with :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_MUTEX`. 2080 2081 * Added MCUmgr settings management group, which allows for manipulation of 2082 zephyr settings from a remote device, see :ref:`mcumgr_smp_group_3` for 2083 details. 2084 2085 * Added :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_CONFIRM_NON_ACTIVE_IMAGE_SECONDARY` 2086 and :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_CONFIRM_NON_ACTIVE_IMAGE_ANY` 2087 that allow to control whether MCUmgr client will be allowed to confirm 2088 non-active images. 2089 2090 * Added :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_ERASE_PENDING` that allows 2091 to erase slots pending for next boot, that are not revert slots. 2092 2093 * Added ``user_data`` as an optional field to :c:struct:`mgmt_handler` when 2094 :kconfig:option:`CONFIG_MCUMGR_MGMT_HANDLER_USER_DATA` is enabled. 2095 2096 * Added optional ``force`` parameter to os mgmt reset command, this can be checked in the 2097 :c:enumerator:`MGMT_EVT_OP_OS_MGMT_RESET` notification callback whose data structure is 2098 :c:struct:`os_mgmt_reset_data`. 2099 2100 * Added configurable number of SMP encoding levels via 2101 :kconfig:option:`CONFIG_MCUMGR_SMP_CBOR_MIN_ENCODING_LEVELS`, which automatically increments 2102 minimum encoding levels for in-tree groups if :kconfig:option:`CONFIG_ZCBOR_CANONICAL` is 2103 enabled. 2104 2105 * Added STM32 SPI backend for EC Host command protocol. 2106 2107 * Fixed settings_mgmt returning unknown error instead of invalid key specified error. 2108 2109 * Fixed fs_mgmt returning parameter too large error instead of file is empty error when 2110 attempting to hash/checksum a file which is empty. 2111 2112* File systems 2113 2114 * Added support for ext2 file system. 2115 * Added support of mounting littlefs on the block device from the shell/fs. 2116 * Added alignment parameter to FS_LITTLEFS_DECLARE_CUSTOM_CONFIG macro, it can speed up read/write 2117 operation for SDMMC devices in case when we align buffers on CONFIG_SDHC_BUFFER_ALIGNMENT, 2118 because we can avoid extra copy of data from card buffer to read/prog buffer. 2119 2120* Random 2121 2122 * ``CONFIG_XOROSHIRO_RANDOM_GENERATOR``, deprecated a long time ago, is finally removed. 2123 2124* Retention 2125 2126 * Added the :ref:`blinfo_api` subsystem. 2127 2128 * Added support for allowing mutex support to be forcibly disabled with 2129 :kconfig:option:`CONFIG_RETENTION_MUTEX_FORCE_DISABLE`. 2130 2131* Binary descriptors 2132 2133 * Added the :ref:`binary_descriptors` (``bindesc``) subsystem. 2134 2135* POSIX API 2136 2137 * Added dynamic thread stack support for :c:func:`pthread_create` 2138 * Fixed :c:func:`stat` so that it returns file stats instead of filesystem stats 2139 * Implemented :c:func:`pthread_barrierattr_destroy`, :c:func:`pthread_barrierattr_getpshared`, 2140 :c:func:`pthread_barrierattr_init`, :c:func:`pthread_barrierattr_setpshared`, 2141 :c:func:`pthread_condattr_destroy`, :c:func:`pthread_condattr_init`, 2142 :c:func:`pthread_mutexattr_destroy`, :c:func:`pthread_mutexattr_init`, :c:func:`uname`, 2143 :c:func:`sigaddset`, :c:func:`sigdelset`, :c:func:`sigemptyset`, :c:func:`sigfillset`, 2144 :c:func:`sigismember`, :c:func:`strsignal`, :c:func:`pthread_spin_destroy`, 2145 :c:func:`pthread_spin_init`, :c:func:`pthread_spin_lock`, :c:func:`pthread_spin_trylock`, 2146 :c:func:`pthread_spin_unlock`, :c:func:`timer_getoverrun`, :c:func:`pthread_condattr_getclock`, 2147 :c:func:`pthread_condattr_setclock`, :c:func:`clock_nanosleep` 2148 * Added support for querying the number of bytes available to read via the 2149 :c:macro:`FIONREAD` request to :c:func:`ioctl` 2150 * Added :kconfig:option:`CONFIG_FDTABLE` to conditionally compile file descriptor table 2151 * Added logging to POSIX threads, mutexes, and condition variables 2152 * Fixed :c:func:`poll` issue with event file descriptors 2153 2154* LoRa/LoRaWAN 2155 2156 * Updated ``loramac-node`` from v4.6.0 to v4.7.0 2157 2158* CAN ISO-TP 2159 2160 * Added support for CAN FD. 2161 2162* RTIO 2163 2164 * Added atomic completion counter fixing a race caught by unit tests 2165 * Added a :c:macro:`RTIO_SQE_NO_RESPONSE` flag for submissions when no completion notification 2166 is needed 2167 * Removed unused Kconfig options for different executors 2168 2169* ZBus 2170 2171 * Changed channels' and observers' metadata to comply with the data/config approach. ZBus stores 2172 immutable config in iterable sections in Flash and the mutable portion of data in the RAM. 2173 * The relationship between channels and observers is mapped using a new entity called 2174 observation. The observation enables us to increase the granularity of masking observation. 2175 Developers can mask individual observations, disable the observer, or use runtime observers. 2176 * Added API :c:macro:`ZBUS_CHAN_ADD_OBS` macro for adding post-definition static observers of a 2177 channel. That can replace the runtime observer feature, enabling developers to add static 2178 observers after the channel definition in different files. It increases the composability of 2179 the system using ZBus, making post-definition channel observation rely on the stack instead of 2180 the heap. 2181 * Added a new type of observer called Message Subscriber. ZBus' VDED will send a copy of the 2182 message during the publication/notification process. 2183 * Changed the VDED delivery sequence. Check the ref:`documentation<zbus delivery sequence>`. 2184 * ZBus runtime observers now rely on the heap instead of a memory pool. 2185 * Added new iterable section iterators APIs (for channels and observers) can now receive a 2186 ``user_data`` pointer to keep context between the function calls. 2187 * Added APIs :c:macro:`ZBUS_LISTENER_DEFINE_WITH_ENABLE` and 2188 :c:macro:`ZBUS_SUBSCRIBER_DEFINE_WITH_ENABLE` that allows developers to define observers' 2189 statuses (enabled/disabled) programmatically. With the API, developers can create observers 2190 initially disabled and enable them in runtime. 2191 2192* Power management 2193 2194 * Added :kconfig:option:`CONFIG_PM_NEED_ALL_DEVICES_IDLE`. When this 2195 option is set the power management will keep the system active 2196 if there is any device busy. 2197 * :c:func:`pm_device_runtime_get` can be called from ISR now. 2198 * Power states can be disabled directly in devicetree doing ``status = "disabled";`` 2199 * Added the helper function, :c:func:`pm_device_driver_init`, for 2200 initializing devices into a specific power state. 2201 2202* Modem modules 2203 2204 * Added the :ref:`modem` subsystem. 2205 2206HALs 2207**** 2208 2209* Nordic 2210 2211 * Updated nrfx to version 3.1.0. 2212 2213* Nuvoton 2214 2215 * Added Nuvoton NuMaker M46x 2216 2217MCUboot 2218******* 2219 2220 * Added :kconfig:option:`CONFIG_MCUBOOT_BOOTLOADER_NO_DOWNGRADE` 2221 that allows to inform application that the on-board MCUboot has been configured 2222 with downgrade prevention enabled. This option is automatically selected for 2223 DirectXIP mode and is available for both swap modes. 2224 2225 * Added :kconfig:option:`CONFIG_MCUBOOT_BOOTLOADER_MODE_OVERWRITE_ONLY` 2226 that allows to inform application that the on-board MCUboot will overwrite 2227 the primary slot with secondary slot contents, without saving the original 2228 image in primary slot. 2229 2230 * Fixed issue with serial recovery not showing image details for decrypted images. 2231 2232 * Fixed issue with serial recovery in single slot mode wrongly iterating over 2 image slots. 2233 2234 * Fixed an issue with boot_serial repeats not being processed when output was sent, this would 2235 lead to a divergence of commands whereby later commands being sent would have the previous 2236 command output sent instead. 2237 2238 * Fixed an issue with the boot_serial zcbor setup encoder function wrongly including the buffer 2239 address in the size which caused serial recovery to fail on some platforms. 2240 2241 * Fixed wrongly building in optimize for debug mode by default, this saves a significant amount 2242 of flash space. 2243 2244 * Fixed issue with serial recovery use of MBEDTLS having undefined operations which led to usage 2245 faults when the secondary slot image was encrypted. 2246 2247 * Fixed issue with bootutil asserting on maximum alignment in non-swap modes. 2248 2249 * Added error output when flash device fails to open and asserts are disabled, which will now 2250 panic the bootloader. 2251 2252 * Added currently running slot ID and maximum application size to shared data function 2253 definition. 2254 2255 * Added P384 and SHA384 support to imgtool. 2256 2257 * Added optional serial recovery image state and image set state commands. 2258 2259 * Added ``dumpinfo`` command for signed image parsing in imgtool. 2260 2261 * Added ``getpubhash`` command to dump the sha256 hash of the public key in imgtool. 2262 2263 * Added support for ``getpub`` to print the output to a file in imgtool. 2264 2265 * Added support for dumping the raw versions of the public keys in imgtool. 2266 2267 * Added support for sharing boot information with application via retention subsystem. 2268 2269 * Added support for serial recovery to read and handle encrypted seondary slot partitions. 2270 2271 * Removed ECDSA P224 support. 2272 2273 * Removed custom image list boot serial extension support. 2274 2275 * Reworked boot serial extensions so that they can be used by modules or from user repositories 2276 by switching to iterable sections. 2277 2278 * Reworked image encryption support for Zephyr, static dummy key files are no longer in the code, 2279 a pem file must be supplied to extract the private and public keys. The Kconfig menu has 2280 changed to only show a single option for enabling encryption and selecting the key file. 2281 2282 * Reworked the ECDSA256 TLV curve agnostic and renamed it to ``ECDSA_SIG``. 2283 2284 * CDDL auto-generated function code has been replaced with zcbor function calls, this now allows 2285 the parameters to be supplied in any order. 2286 2287 * The MCUboot version in this release is version ``2.0.0+0-rc1``. 2288 2289Nanopb 2290****** 2291 2292 * Changed project status to maintained. 2293 2294 * Added a separate nanopb.cmake file to be included by applications. 2295 2296 * Added helper cmake function ``zephyr_nanopb_sources`` to simplify ``.proto`` file inclusion. 2297 2298LVGL 2299**** 2300 2301 * Changed project status to maintained. 2302 2303 * Library has been updated to release v8.3.7. 2304 2305 * Added ``zephyr,lvgl-{pointer,button,encoder}-input`` pseudo device bindings. 2306 :kconfig:option:`CONFIG_LV_Z_KSCAN_POINTER` is still supported but touch controllers 2307 need a :dtcompatible:`zephyr,kscan-input` child node to emit input events. 2308 2309 * LVGL shell allows for monkey testing (requires :kconfig:option:`CONFIG_LV_USE_MONKEY`) 2310 and inspecting memory usage. 2311 2312Trusted Firmware-A 2313****************** 2314 2315* Updated to TF-A 2.9.0. 2316 2317Documentation 2318************* 2319 2320* Upgraded Sphinx to 6.2 2321 2322Tests and Samples 2323***************** 2324 2325* Created common sample for file systems (`fs_sample`). It originates from sample for FAT 2326 (`fat_fs`) and supports both FAT and ext2 file systems. 2327 2328* Created the zbus confirmed channel sample to demonstrate how to implement a delivery-guaranteed 2329 channel using subscribers. 2330 2331* Created the zbus message subscriber sample to demonstrate how to use message subscribers. 2332
