	- first release

	29-05-2003
	- exchanged usb connector with FT245BM
	- use alternative circuitry of self powered
	  mode
	- modified footprint of 74AHC1G125
	- added pullups on strobe and autofeed of
	  parallel port
	- added pullup on Rxd input
	- exchanged autofeed and init connections
	  to the ATmega128
	- added pullup resistors for parallel port
	- bumped to version 1.1

	16-08-2003
	- put restrictions on the border of the pcb
	- added layer identification
	- 1 set is for pcb layout production :
	  this is defined as *.gpi, *.grb, *.drd
	  and *.drl
	- 1 set is pure for documentation :
	  all files ending in *.ps (postscript). The
	  size seen in *.ps is 1.8 times the original.
	- one file (gdb_new.drd) is added to view
	  correctly with gerbv-0.13 (free gerber viewer)
	- changed "12 DC to 20 V" to "12V AC to 20 V" in
	  schematic diagram
	- changed readme.txt into gdb_serializer.doc
	- added rudimentary partlist
	- added readme.txt

	17-08-2003
	- changed to version 1.3
	- ieee1284 connector (parallel port connector) changed
	  into receptable ieee1284C
	- added 74VHC125M instead of 2 separate tristate ports
	- changed connection of TDO ARM7/9 jtag. The used
	  configuration would prevent AVR TDO output to be
	- deleted LED circuit to show BDM/JTAG activity
	- added partlist in both postscript and openoffice
	  format
	- added assembly instruction in openoffice format
	- adapted the description and is in openoffice format 
	- changed boardsizes to really 100 mm x 100 mm
	- changed the text on the pcb (is thicker)
	- changed the inner layers now drawn with polygons
	- only one minor error exists but can be ignored
	- shifted up the pcb layout 
	- put the origin of the layout to the origin of Eagle

	27-02-2004
