		* Added support for these SoC series:

		* Added ESP32-C2 and ESP8684 SoC support.
		* Added STM32U0 series with GPIO, Serial, I2C, DAC, ADC, flash, PWM and counter driver support.
		* Added STM32WB0 series with GPIO, Serial, I2C, SPI, ADC, DMA and flash driver support.
		* Added STM32U545xx SoC variant.

		* Made these changes in other SoC series:

		* NXP S32Z270: Added support for the new silicon cut version 2.0. Note that the previous
		versions (1.0 and 1.1) are no longer supported.
		* Added ESP32 WROVER-E-N16R4 variant.
		* STM32H5: Added support for OpenOCD through STMicroelectronics OpenOCD fork.

		* Support for Google Kukui EC board (``google_kukui``) has been dropped.
		* STM32: Deprecated MCO configuration via Kconfig in favour of setting it through devicetree.
		See ``samples/boards/stm32/mco`` sample.
		* STM32: STM32CubeProgrammer is now the default runner on all STMicroelectronics STM32 boards.
		* Removed the ``nrf54l15pdk`` board, use :ref:`nrf54l15dk_nrf54l15` instead.
		* PHYTEC: ``mimx8mp_phyboard_pollux`` has been renamed to :ref:`phyboard_pollux<phyboard_pollux>`,
		with the old name marked as deprecated.

		* STM32: :kconfig:option:`CONFIG_CLOCK_CONTROL` is now enabled by default at family level and doesn't need
		to be enabled at board level anymore.
		* STM32H7: PLL FRACN can now be configured (see :dtcompatible:`st,stm32h7-pll-clock`)

		* Ethernet

		* LiteX: Renamed the ``compatible`` from ``litex,eth0`` to :dtcompatible:`litex,liteeth`.
		* STM32: Driver can now be configured to use a preemptive RX thread priority, which could be useful
		in case of high network traffic load (reduces jitter).

		* Flash

		* Fixed SPI NOR driver issue where wp, hold and reset pins were incorrectly initialized from
		device tee when SFDP at run-time has been enabled (:github:`80383`)
		* Updated all Espressif's SoC driver initialization to allow new chipsets and octal flash support.

		* Added :kconfig:option:`CONFIG_SPI_NOR_ACTIVE_DWELL_MS`, to the SPI NOR driver configuration,
		which allows setting the time during which the driver will wait before triggering Deep Power Down (DPD).
		This option replaces ``CONFIG_SPI_NOR_IDLE_IN_DPD``, aiming at reducing unnecessary power
		state changes and SPI transfers between other operations, specifically when burst type
		access to an SPI NOR device occurs.

		* Added :kconfig:option:`CONFIG_SPI_NOR_INIT_PRIORITY` to allow selecting the SPI NOR driver initialization priority.

		* The flash API has been extended with the :c:func:`flash_copy` utility function which allows performing
		direct data copies between two Flash API devices.

		* Fixed a Flash Simulator issue where offsets were assumed to be absolute instead of relative
		to the device base address (:github:`79082`).
		* Extended STM32 OSPI drivers to support QUAL, DUAL and SPI modes. Additionally, added support
		for custom write and SFDP:BFP opcodes.
		* Added possibility to run STM32H7 flash driver from Cortex-M4 core.
		* Implemented readout protection handling (RDP levels) for STM32F7 SoCs.
