+ * - The non-standard "Ready" host state has been removed. Existing \ref HOST_STATE_Configured code should be moved to the end of\r
+ * the existing \ref HOST_STATE_Addressed state, and the existing HOST_STATE_Ready state code should be moved to the \ref HOST_STATE_Configured\r
+ * state.\r
+ * - The USB_IsConnected global has been removed, as it is too vague for general use. Test \ref USB_HostState explicitly to ensure the host is\r
+ * in the desired state instead.\r
+ * - The USB event names have been changed and their firing conditions changed to properly seperate out Host mode events from Device mode\r
+ * events. See the \ref Group_Events page for details on the new event names and firing conditions.\r

+ * <b>Device Mode</b>\r
+ * - The \ref CALLBACK_USB_GetDescriptor() function now takes an extra parameter to specify the descriptor's memory space so that\r
+ * descriptors in mixed memory spaces can be used. The previous functionality can be returned by defining the USE_FLASH_DESCRIPTORS\r
+ * token in the project makefile to fix all descriptors into FLASH space and remove the extra function parameter.\r
+ * - The USB_IsSuspended global has been removed - test \ref USB_DeviceState against \ref DEVICE_STATE_Suspended instead.\r
+ * - The USB_IsConnected global has been removed, as it is too vague for general use. Test \ref USB_DeviceState explicitly to ensure the device\r
+ * is in the desired state instead.\r
+ * - The VBUS events have been removed, as they are already exposed to the user via the USB_Connect and USB_Disconnect events.\r
+ * - The USB event names have been changed and their firing conditions changed to properly seperate out Host mode events from Device mode\r
+ * events. See the \ref Group_Events page for details on the new event names and firing conditions. *\r
