| Zephyr 2.3.0 (Working Draft) |
| ############################ |
| |
| We are pleased to announce the release of Zephyr RTOS version 2.3.0. |
| |
| Major enhancements with this release include: |
| |
| * <TBD> |
| |
| The following sections provide detailed lists of changes by component. |
| |
| Security Vulnerability Related |
| ****************************** |
| |
| No security vulnerabilities received. |
| |
| API Changes |
| *********** |
| |
| * HWINFO |
| |
| * The identifier data structure for hwinfo drivers is clarified. Drivers are |
| responsible for ensuring that the identifier data structure is a sequence |
| of bytes. The returned ID value is not supposed to be interpreted based on |
| vendor-specific assumptions of byte order and should express the identifier |
| as a raw byte sequence. |
| The changes have an impact on users that use the hwinfo API to identify |
| their devices. |
| The sam0 driver byte swaps each 32 bit word of the 128 bit identifier to |
| big endian. |
| The nordic driver byte swaps the entire 64 bit word to big endian. |
| |
| Deprecated in this release |
| ========================== |
| |
| * Kernel |
| |
| * k_uptime_delta_32(), use k_uptime_delta() |
| * Timeout values |
| |
| * All timeout values are now encapsulated k_timeout_t opaque structure when |
| passing them to the kernel. If you want to revert to the previous s32_t |
| type for the timeout parameter, please enable |
| :option:`CONFIG_LEGACY_TIMEOUT_API` |
| |
| * Bluetooth |
| |
| * BT_LE_SCAN_FILTER_DUPLICATE, use BT_LE_SCAN_OPT_FILTER_DUPLICATE instead |
| * BT_LE_SCAN_FILTER_WHITELIST, use BT_LE_SCAN_OPT_FILTER_WHITELIST instead |
| * bt_le_scan_param::filter_dup, use bt_le_scan_param::options instead |
| * bt_conn_create_le(), use bt_conn_le_create() instead |
| * bt_conn_create_auto_le(), use bt_conn_le_create_auto() instead |
| * bt_conn_create_slave_le(), use bt_le_adv_start() instead with |
| bt_le_adv_param::peer set to the remote peers address. |
| * BT_LE_ADV_* macros, use BT_GAP_ADV_* enums instead |
| |
| * Boards |
| |
| * nrf51_pca10028 has been renamed to nrf51dk_nrf51422 |
| * nrf51_pca10031 has been renamed to nrf51dongle_nrf51422 |
| * nrf52810_pca10040 has been renamed to nrf52dk_nrf52810 |
| * nrf52_pca10040 has been renamed to nrf52dk_nrf52832 |
| * nrf52833_pca10100 has been renamed to nrf52833dk_nrf52833 |
| * nrf52811_pca10056 has been renamed to nrf52840dk_nrf52811 |
| * nrf52840_pca10056 has been renamed to nrf52840dk_nrf52840 |
| * nrf52840_pca10059 has been renamed to nrf52840dongle_nrf52840 |
| * nrf9160_pca10090 has been renamed to nrf9160dk_nrf9160 |
| * nrf52840_pca10090 has been renamed to nrf9160dk_nrf52840 |
| * nrf52_pca20020 has been renamed to thingy52_nrf52832 |
| * nrf5340_dk_nrf5340 has been renamed to nrf5340pdk_nrf5340 |
| |
| * Devicetree |
| |
| * The C macros generated from devicetree. Use the new ``<devicetree.h>`` |
| accessor API instead; see :ref:`dt-guide` for details. Use of the legacy |
| macros requires enabling :option:`CONFIG_LEGACY_DEVICETREE_MACROS`. |
| |
| Removed APIs in this release |
| ============================ |
| |
| |
| Stable API changes in this release |
| ================================== |
| |
| * Bluetooth Mesh |
| |
| * The net_idx parameter has been removed from the Health Client model |
| APIs since it can be derived (by the stack) from the app_idx parameter |
| |
| * Networking |
| |
| * The NET_DEVICE_INIT(), NET_DEVICE_INIT_INSTANCE(), NET_DEVICE_OFFLOAD_INIT() |
| and ETH_NET_DEVICE_INIT() macros changed and take a device power management |
| function pointer parameter. If networking PM is not implemented for the |
| specific network device, the device_pm_control_nop value can be used. |
| |
| * Video |
| |
| * The video_dequeue() API call now takes a k_timeout_t for the timeout |
| parameter. This reverts to s32_t if CONFIG_LEGACY_TIMEOUT_API is enabled. |
| |
| * Floating Point Services |
| |
| * FLOAT and FP_SHARING Kconfig options have been renamed to FPU and FPU_SHARING, |
| respectively. |

| |
| * Devicetree |
| |
| * A new :ref:`devicetree_api` was added. This API is not generated, but is |
| still included via ``<devicetree.h>``. The :ref:`dt-legacy-macros` are now |
| deprecated; users should replace the generated macros with new API. The |
| :ref:`dt-howtos` page has been extended for the new API, and a new |
| :ref:`dt-from-c` API usage guide was also added. |
