>>> UsbWidEx Version History <<<
                  ========================

V1.00:	(May 2013) first release:
	* Drive backup & restore via XMODEM connection. Detects drive type, 
	  including IDEfile volume number. 532 and 1024 byte blocks and BLU
	  header supported.
	* Widget servo debugger with Alternate Seek mode for optics alignment.
	* ProFile/Widget debugger: general R/W commands, Widget diag commands,
	  Widget status decoding
	* Line sniffer mode not working. µC seems to be to slow to catch
	  strobe pulses.
	* Surface Scan and Low Level Format procedures not implemented yet
	  (though the commands are available in debug mode).

V1.01:	(December 2013) new features:
	* Line sniffer code dropped.
	* Code reorganized. Low level procedured and general R/W in 
	  drivecmds.h. All low-level and general R/W functions only return 
	  1 = passed or 0 = failed, all error handling and reporting is done
	  internally. Trace mode off suppresses error messages (e.g. during
	  XMODEM).
	* separate debug modes for ProFile and Widget. ProFile mode supports
	  Create Spare (03) command and diagnostic read/write loops (to align 
	  the analog board circuits).

V1.02:	(April 2014) new features:
	* low level format and surface test procedures added
	* ProFile 10M has a completely different diag command set, so a new menu
	  was required. Common procedures have been moved into libraries
	* auto-increment function added for read, write, loop on R/W and seek

V1.03:	(January 2019) fixes:
	* scan result from PF5 LLF now reported for the first 32 bad blocks only 
	* bug fixed in bin/hex conversion of LBA number in bad block substitution 
	  text. Bad block count added. Format is now "0001:   0x001234".
	* DiagReadHeader now transfers 0x228 bytes
