| Zephyr 3.7.0 (Working Draft) |
| ############################ |
| |
| We are pleased to announce the release of Zephyr version 3.7.0. |
| |
| Major enhancements with this release include: |
| |
| * A new, completely overhauled hardware model has been introduced. This changes |
| the way both SoCs and boards are named, defined and constructed in Zephyr. |
| Additional information can be found in the :ref:`board_porting_guide`. |
| |
| An overview of the changes required or recommended when migrating your application from Zephyr |
| v3.6.0 to Zephyr v3.7.0 can be found in the separate :ref:`migration guide<migration_3.7>`. |
| |
| The following sections provide detailed lists of changes by component. |
| |
| Security Vulnerability Related |
| ****************************** |
| The following CVEs are addressed by this release: |
| |
| More detailed information can be found in: |

| |
| Architectures |
| ************* |
| |
| * ARC |
| |
| * ARM |
| |
| * Xtensa |
| |
| Bluetooth |
| ********* |
| |
| * Added Nordic UART Service (NUS), enabled by the :kconfig:option:`CONFIG_BT_NUS`. |
| This Service exposes the ability to declare multiple instances of the GATT service, |
| allowing multiple serial endpoints to be used for different purposes. |
| |
| Boards & SoC Support |
| ******************** |
| |
| * Added support for these SoC series: |
| |
| * Made these changes in other SoC series: |
| |
| * Added support for these ARM boards: |
| |
| * Added support for these Xtensa boards: |
| |
| * Made these changes for ARM boards: |
| |
| * Made these changes for RISC-V boards: |
| |
| * Made these changes for native/POSIX boards: |
| |
| * Added support for these following shields: |

| Drivers and Sensors |
| ******************* |
| |
| * ADC |
| |
| * Auxiliary Display |
| |
| * Audio |
| |
| * Battery |
| |
| * Added ``re-charge-voltage-microvolt`` property to the ``battery`` binding. This allows to set |
| limit to automatically start charging again. |
| |
| * Battery backed up RAM |
| |
| * CAN |
| |
| * Deprecated the :c:func:`can_calc_prescaler` API function, as it allows for bitrate |
| errors. Bitrate errors between nodes on the same network leads to them drifting apart after the |
| start-of-frame (SOF) synchronization has taken place, leading to bus errors. |
| * Extended support for automatic sample point location to also cover :c:func:`can_calc_timing` and |
| :c:func:`can_calc_timing_data`. |
| * Added optional ``min-bitrate`` devicetree property for CAN transceivers. |
| * Added devicetree macros :c:macro:`DT_CAN_TRANSCEIVER_MIN_BITRATE` and |
| :c:macro:`DT_INST_CAN_TRANSCEIVER_MIN_BITRATE` for getting the minimum supported bitrate of a CAN |
| transceiver. |
| * Added support for specifying the minimum bitrate supported by a CAN controller in the internal |
| ``CAN_DT_DRIVER_CONFIG_GET`` and ``CAN_DT_DRIVER_CONFIG_INST_GET`` macros. |
| * Added a new CAN controller API function :c:func:`can_get_min_bitrate` for getting the minimum |
| supported bitrate of a CAN controller/transceiver combination. |
| * Updated the CAN timing functions to take the minimum supported bitrate into consideration when |
| validating the bitrate. |
| * Made the ``sample-point`` and ``sample-point-data`` devicetree properties optional. |
| |
| * Charger |
| |
| * Added ``chgin-to-sys-current-limit-microamp`` property to ``maxim,max20335-charger``. |
| * Added ``system-voltage-min-threshold-microvolt`` property to ``maxim,max20335-charger``. |
| * Added ``re-charge-threshold-microvolt`` property to ``maxim,max20335-charger``. |
| * Added ``thermistor-monitoring-mode`` property to ``maxim,max20335-charger``. |

| enables using Bluetooth as a transport to all the subsystems that are currently supported by |
| UART (e.g: Console, Shell, Logging). |

| Tests and Samples |
| ***************** |
| |
| * Added snippet for easily enabling UART over Bluetooth LE by passing ``-S nus-console`` during |
| ``west build``. This snippet sets the :kconfig:option:`CONFIG_BT_NUS_AUTO_START_BLUETOOTH` |
| which allows non-Bluetooth samples that use the UART APIs to run without modifications |
| (e.g: Console and Logging examples). |
