9 * \section Sec_ChangeLogXXXXXX Version XXXXXX
11 * - Added new SCSI_ASENSE_NOT_READY_TO_READY_CHANGE constant to the Mass Storage class driver, to indicate when a previously

21 * - Added new project makefile template to the library and moved board driver stub files into in a new "CodeTemplates" directory
24 * - Removed complicated logic for the Endpoint_ConfigureEndpoint() function to use inlined or function called versions
25 * depending of if the given bank size is a compile time constant, as the compiler does a better job of optimizing
27 * - Changed over all device demos to use a clearer algorithm for the configuring of the application's endpoints
28 * - Added missing DataflashManager_CheckDataflashOperation() function to the MassStorageKeyboard demo, removed redundant
29 * SCSI_Codes.h file as these values are part of the MassStorage Class Driver
30 * - Added compile time error to the AVRISP-MKII project when built for the U4 chips, as the default VTARGET detection ADC channel
31 * does not exist on these chips (thanks to Marco)
32 * - Changed all Device mode LowLevel demos and Device Class drivers so that the control request is acknowledged and any data
33 * transferred as quickly as possible without any processing inbetween sections, so that long callbacks or event handlers will
34 * not break communications with the host by exceeding the maximum control request stage timeout period
35 * - Changed the signature of the CALLBACK_USB_GetDescriptor() callback function so that the descriptor pointer is const, to remove
36 * the need for extra casting inside the callback (thanks to Jonathan Kollasch)

38 * - Changed over all demos, drivers and internal functions to use the current frame number over the Start of Frame flag where possible
39 * to free up the Start of Frame flag for interrupt use in the user application
42 * - Fixed USB_GetHIDReportItemInfo() function modifying the given report item's data when the report item does not exist
43 * within the supplied report of a multiple report HID device
44 * - Fixed MassStorage based demos and projects resetting the SCSI sense values before the command is executed, leading to
45 * missed SCSI sense values when the host retrieves the sense key (thanks to Martin Degelsegger)
46 * - Fixed critical pipe/endpoint memory allocation issue where the bank memory address space could be silently overlapped
47 * in the USB controller if the endpoints or pipes were allocated in anything other than ascending order (thanks to Martin Degelsegger)
48 * - Fixed USBtoSerial and Benito project SetLineEncoding calls failing if the USART is busy, due to the RX ISR delaying the control
50 * - Fixed LowLevel PrinterHost demo not sending control requests to the attached printer with the correct printer interface wIndex value

75 * parameters to EEPROM to preserve its lifespan
