+ * - The USB_CONFIG_ATTR_BUSPOWERED constant has been renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed. All devices must set this bit in
+ * the Configuration descriptor's attributes field. As all devices are assumed to be bus-powered unless stated otherwise with the
+ * USB_CONFIG_ATTR_SELFPOWERED flag a replacement constant for bus powered devices is not provided.
+ *
+ * <b>Device Mode</b>
+ * - The device mode Audio class driver now requires a new user application callback, \ref CALLBACK_Audio_Device_GetSetInterfaceProperty().
+ * Existing applications must implement this new callback, however if no audio entities are defined in the audio device's descriptors,
+ * this function may be hard-coded to always return false for previous behaviour to be retained.
