• Device runtime power management (PM), former IDLE runtime, was completely overhauled.
• Added an example standalone Zephyr application in its own Git repository:
  https://github.com/zephyrproject-rtos/example-application

The following sections provide detailed lists of changes by component.

• CVE-2021-3581: Under embargo until 2021-09-04

Known issues

You can check all currently known issues by listing them using the GitHub
interface and listing all issues with the bug label <https://github.com/zephyrproject-rtos/zephyr/issues?q=is%3Aissue+is%3Aopen+label%3Abug>_.

API Changes

• Driver APIs now return -ENOSYS if optional functions are not implemented. If the feature is not supported by the hardware -ENOTSUP will be returned. Formerly -ENOTSUP was returned for both failure modes, meaning this change may require existing code that tests only for that value to be changed.

• The wait_for_usb_dfu function now accepts a k_timeout_t argument instead of using the CONFIG_USB_DFU_WAIT_DELAY_MS macro.

• Added disconnect reason to the disconnected callback of :c:struct:bt_iso_chan_ops.

• Align error handling of bt_l2cap_chan_send and bt_iso_chan_send so when an error occur the buffer is not unref.

• Added lwm2m_engine_delete_obj_inst function to the LwM2M library API.

Deprecated in this release

• DT_CLOCKS_LABEL_BY_IDX, DT_CLOCKS_LABEL_BY_NAME, DT_CLOCKS_LABEL, DT_INST_CLOCKS_LABEL_BY_IDX, DT_INST_CLOCKS_LABEL_BY_NAME, and DT_INST_CLOCKS_LABEL was deprecated in favor of utilizing DT_CLOCKS_CTLR and variants.

• DT_PWMS_LABEL_BY_IDX, DT_PWMS_LABEL_BY_NAME, DT_PWMS_LABEL, DT_INST_PWMS_LABEL_BY_IDX, DT_INST_PWMS_LABEL_BY_NAME, and DT_INST_PWMS_LABEL was deprecated in favor of utilizing DT_PWMS_CTLR and variants.

• DT_IO_CHANNELS_LABEL_BY_IDX, DT_IO_CHANNELS_LABEL_BY_NAME, DT_IO_CHANNELS_LABEL, DT_INST_IO_CHANNELS_LABEL_BY_IDX, DT_INST_IO_CHANNELS_LABEL_BY_NAME, and DT_INST_IO_CHANNELS_LABEL were deprecated in favor of utilizing DT_IO_CHANNELS_CTLR and variants.

• DT_DMAS_LABEL_BY_IDX, DT_DMAS_LABEL_BY_NAME, DT_INST_DMAS_LABEL_BY_IDX, and DT_INST_DMAS_LABEL_BY_NAME were deprecated in favor of utilizing DT_DMAS_CTLR and variants.

• USB HID specific macros in <include/usb/class/usb_hid.h> are deprecated in favor of new common HID macros defined in <include/usb/class/hid.h>.

• USB HID Kconfig option USB_HID_PROTOCOL_CODE is deprecated. USB_HID_PROTOCOL_CODE does not allow to set boot protocol code for specific HID device. USB HID API function usb_hid_set_proto_code() can be used instead.

• USB HID class API is changed by removing get_protocol/set_protocol and get_idle/set_idle callbacks. These callbacks are redundant or do not provide any additional value and have led to incorrect usage of HID class API.

• The CONFIG_OPENOCD_SUPPORT Kconfig option has been deprecated in favor of CONFIG_DEBUG_THREAD_INFO.

• Disk API header <include/disk/disk_access.h> is deprecated in favor of <include/storage/disk_access.h>.

• flash_write_protection_set().

• The CONFIG_NET_CONTEXT_TIMESTAMP is removed as it was only able to work with transmitted data. The same functionality can be achieved by setting CONFIG_NET_PKT_RXTIME_STATS and CONFIG_NET_PKT_TXTIME_STATS options. These options are also able to calculate the RX & TX times more accurately. This means that support for the SO_TIMESTAMPING socket option is also removed as it was used by the removed config option.

• The device power management (PM) APIs and data structures have been renamed from device_pm_* to pm_device_* since they are not device APIs but PM subsystem APIs. The same applies to enumerations and definitions, they now follow the PM_DEVICE_* convention. Some other API calls such as device_set_power_state and device_get_power_state have been renamed to pm_device_state_set and pm_device_state_get in order to align with the naming of other device PM APIs.

• The runtime device power management (PM) APIs is now synchronous by default and the asynchronous API has the _async sufix. This change aligns the API with the convention used in Zephyr. The affected APIs are pm_device_put and pm_device_get.

• The following functions, macros, and structures related to the kernel work queue API:

  • k_work_pending() replace with k_work_is_pending()
  • k_work_q_start() replace with k_work_queue_start()
  • :c:struct:k_delayed_work replace with :c:struct:k_work_delayable
  • k_delayed_work_init() replace with k_work_init_delayable
  • k_delayed_work_submit_to_queue() replace with k_work_schedule_for_queue() or k_work_reschedule_for_queue()
  • k_delayed_work_submit() replace with k_work_schedule() or k_work_reschedule()
  • k_delayed_work_pending() replace with k_work_delayable_is_pending()
  • k_delayed_work_cancel() replace with k_work_cancel_delayable()
  • k_delayed_work_remaining_get() replace with k_work_delayable_remaining_get()
  • k_delayed_work_expires_ticks() replace with k_work_delayable_expires_get()
  • k_delayed_work_remaining_ticks() replace with k_work_delayable_remaining_get()
  • K_DELAYED_WORK_DEFINE replace with K_WORK_DELAYABLE_DEFINE

Removed APIs in this release

• Removed support for k_mem_domain_destroy and k_mem_domain_remove_thread

• Removed support for counter_read and counter_get_max_relative_alarm

  • Extended the pagetable generation script to allow specifying additional memory mapping during build.

  • x86-32

    • Added support for kernel image to reside in virtual address space, allowing code execution and data manipulation via virtual addresses.
