   *   - AVRISP-MKII Clone Project PDI/TPI frequency increased from 250KHz to 2MHz as it is now stable
   *   - Fixed incorrect signature bytes returned in the DFU bootloader
   *   - Added new libUSB host Python and NodeJS application examples for the class driver GenericHID demo (thanks to Laszlo Monda)
+  *   - Increased TPI/PDI handshake delay to 1ms from 1us to support targets with high amounts of capacitance on their
+  *     /RESET lines (thanks to Paul Duke)
