1:orphan: 2 3.. _zephyr_4.0: 4 5Zephyr 4.0.0 6############ 7 8We are pleased to announce the release of Zephyr version 4.0.0. 9 10Major enhancements with this release include: 11 12* **Secure Storage Subsystem**: 13 A newly introduced :ref:`secure storage<secure_storage>` subsystem allows the use of the 14 PSA Secure Storage API and of persistent keys in the PSA Crypto API on *all* board targets. It 15 is now the standard way to provide device-specific protection to data at rest. (:github:`76222`) 16 17* **ZMS (Zephyr Memory Storage) Subsystem**: 18 :ref:`ZMS <zms_api>` is a new key-value storage subsystem compatible with all non-volatile storage 19 types, including traditional NOR flash and advanced technologies like RRAM and MRAM that support 20 write without erasure. 21 22* **Analog Comparators**: 23 A new :ref:`comparator<comparator_api>` device driver subsystem for analog comparators has been 24 added, complete with shell support. It supports initial configuration through Devicetree and 25 runtime configuration through vendor specific APIs. Initially the :dtcompatible:`nordic,nrf-comp`, 26 :dtcompatible:`nordic,nrf-lpcomp` and :dtcompatible:`nxp,kinetis-acmp` are supported. 27 28* **Stepper Motors**: 29 It is now possible to interact with stepper motors using a standard API thanks to the new 30 :ref:`stepper<stepper_api>` device driver subsystem, which also comes with shell support. 31 Initially implemented drivers include a simple :dtcompatible:`zephyr,gpio-steppers` and a complex 32 sensor-less stall-detection capable with integrated ramp-controller :dtcompatible:`adi,tmc5041`. 33 34* **Haptics**: 35 A new :ref:`haptics_api` device driver subsystem allows unified access to haptic controllers, 36 enabling users to add haptic feedback to their applications. 37 38* **Multimedia Capabilities** 39 Zephyr's audio and video capabilities have been expanded with support for new image sensors, video 40 interfaces, audio interfaces, and codecs being supported. 41 42* **Prometheus Library**: 43 A `Prometheus`_ metrics library has been added to the networking stack. It provides a way to 44 expose metrics to Prometheus clients over HTTP, facilitating the consolidated remote monitoring of 45 Zephyr devices alongside other systems typically monitored using Prometheus. 46 47* **Documentation Improvements**: 48 Several enhancements were made to the online documentation to improve content discovery and 49 navigation. These include a new :ref:`interactive board catalog <boards>` and an interactive 50 directory for :zephyr:code-sample-category:`code samples <samples>`. 51 52* **Expanded Board Support**: 53 Over 60 :ref:`new boards <boards_added_in_zephyr_4_0>` and 54 :ref:`shields <shields_added_in_zephyr_4_0>` are supported in Zephyr 4.0. 55 56.. _`Prometheus`: https://prometheus.io/ 57 58An overview of the changes required or recommended when migrating your application from Zephyr 59v3.7.0 to Zephyr v4.0.0 can be found in the separate :ref:`migration guide<migration_4.0>`. 60 61The following sections provide detailed lists of changes by component. 62 63Security Vulnerability Related 64****************************** 65The following CVEs are addressed by this release: 66 67More detailed information can be found in: 68https://docs.zephyrproject.org/latest/security/vulnerabilities.html 69 70* :cve:`2024-8798`: Under embargo until 2024-11-22 71* :cve:`2024-10395`: Under embargo until 2025-01-23 72* :cve:`2024-11263` `Zephyr project bug tracker GHSA-jjf3-7x72-pqm9 73 <https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-jjf3-7x72-pqm9>`_ 74 75API Changes 76*********** 77 78Removed APIs in this release 79============================ 80 81* Macro ``K_THREAD_STACK_MEMBER``, deprecated since v3.5.0, has been removed. 82 Use :c:macro:`K_KERNEL_STACK_MEMBER` instead. 83 84* ``CBPRINTF_PACKAGE_COPY_*`` macros, deprecated since Zephyr 3.5.0, have been removed. 85 86* ``_ENUM_TOKEN`` and ``_ENUM_UPPER_TOKEN`` macros, deprecated since Zephyr 2.7.0, 87 are no longer generated. 88 89* Removed deprecated arch-level CMSIS header files 90 ``include/zephyr/arch/arm/cortex_a_r/cmsis.h`` and 91 ``include/zephyr/arch/arm/cortex_m/cmsis.h``. ``cmsis_core.h`` needs to be 92 included now. 93 94* Removed deprecated ``ceiling_fraction`` macro. :c:macro:`DIV_ROUND_UP` needs 95 to be used now. 96 97* Removed deprecated header file 98 ``include/zephyr/random/rand32.h``. ``random.h`` needs to be included now. 99 100* Deprecated ``EARLY``, ``APPLICATION`` and ``SMP`` init levels can no longer be 101 used for devices. 102 103* Removed deprecated net_pkt functions. 104 105Deprecated in this release 106========================== 107 108* Deprecated the ``net_buf_put()`` and ``net_buf_get()`` API functions in favor of 109 :c:func:`k_fifo_put` and :c:func:`k_fifo_get`. 110 111* The ``kscan_api`` subsystem has been marked as deprecated. 112 113* Deprecated the TinyCrypt shim driver ``CONFIG_CRYPTO_TINYCRYPT_SHIM``. 114 115* ``native_posix`` has been deprecated in favour of 116 :ref:`native_sim<native_sim>`. 117 118* ``include/zephyr/net/buf.h`` is deprecated in favor of 119 ``include/zephyr/net_buf.h>``.

0.9.0. 1531 Full release notes at https://github.com/NordicSemiconductor/zcbor/blob/0.9.0/RELEASE_NOTES.md 1532 Migration guide at https://github.com/NordicSemiconductor/zcbor/blob/0.9.0/MIGRATION_GUIDE.md 1533 Highlights: 1534 1535 * Many code generation bugfixes 1536 1537 * You can now decide at run-time whether the decoder should enforce canonical encoding. 1538 1539 * Allow --file-header to accept a path to a file with header contents 1540 1541Tests and Samples 1542***************** 1543 1544* Together with the deprecation of ``native_posix``, many tests which were 1545 explicitly run in native_posix now run in :ref:`native_sim<native_sim>` instead. 1546 native_posix as a platform remains tested though. 1547* Extended the tests of counter_basic_api with a testcase for counters without alarms 1548* Added support for testing SDMMC devices to the fatfs API test 1549* Extended net/vlan to add IPv6 prefix config to each vlan-iface 1550* Enhanced the camera fixture test by adding a color bar to enable automation 1551* Added a number crunching (maths such as FFT, echo cancellation) sample using an optimized 1552 library for the NXP ADSP board 1553* Tailored the SPI_LOOPBACK test to the limitations of NXP Kinetis MCU's 1554* Enabled the video sample to run video capture (samples/drivers/video) 1555 1556* Added :zephyr:code-sample:`smf_calculator` sample demonstrating the usage of the State Machine framework 1557 in combination with LVGL to create a simple calculator application. 1558* Consolidated display sample where possible to use a single testcase for all shields 1559 1560Issue Related Items 1561******************* 1562 1563Known Issues 1564============ 1565 1566-
