* \section Sec_ChangeLogXXXXXX Version XXXXXX
*
* <b>New:</b>
* - Added TPI programming support for 6-pin ATTINY to the AVRISP programmer project
*
* <b>Changed:</b>
*
* <b>Fixed:</b>
*
* \section Sec_ChangeLog091223 Version 091223
*
* <b>New:</b>
* - Added activity LED indicators to the AVRISP project to indicate when the device is busy processing a command
* - The USB target family and allowable USB mode tokens are now public and documented (USB_CAN_BE_*, USB_SERIES_*_AVR)
* - Added new XPLAIN USB to Serial Bridge project (thanks to John Steggall for initial proof-of-concept, David Prentice
