* Power management
* Devices can now declare which system power states cause power loss.
This information can be used to set and release power state
constraints when it is needed by the device. This feature is enabled with
:kconfig:option:`CONFIG_PM_POLICY_DEVICE_CONSTRAINTS`. Use functions
:c:func:`pm_policy_device_power_lock_get` and :c:func:`pm_policy_device_power_lock_put`
to lock and unlock all power states that cause power loss in a device.
* Added shell support for device power management.
* Device power management was de-coupled from system power management. The new
:kconfig:option:`CONFIG_PM_DEVICE_SYSTEM_MANAGED` option is used to enable
whether or not devices must be suspended when the system sleeps.
* Make it possible to disable system device power management individually per
power state using ``zephyr,pm-device-disabled``. This allows targets tuning which
states should (and which should not) trigger device power management.
* Crypto
* Mbed TLS was updated to 3.6.0. Release notes can be found at:
