+* Added new header file where all defines and structures from Chapter 9
+  (USB Device Framework) should be included.
+* Revised configuraiton of USB device support.
+  Removed Kconfig option ``CONFIG_USB`` and introduced Kconfig option
+  ``CONFIG_USB_DEVICE_DRIVER`` to enable USB device controller drivers,
+  which is selected when option ``CONFIG_USB_DEVICE_STACK`` is enabled.
+* Enhanced verification of the control request in device stack, classes, and samples.
+* Added support to store alternate interface setting.
+* Added ``zephyr_udc0`` nodelabel to all boards with USB support to allow
+  generic USB device support samples to be build.
+* Reworked descriptors, config, and data definitions macros in CDC ACM class.
+* Changed CDC ACM UART implementation to get configuration from devicetree.
+  With this change, many ``CONFIG_*_ON_DEV_NAME`` options were removed and
+  applications revised. See :ref:`usb_device_cdc_acm` for more information.
