 " History
 "
+" Version 10.0
+"     Cycle through all the character ranges specified in the
+"     iskeyword option and build a list of valid word separators.
+"     Prior to this change, only actual characters were used, 
+"     where for example ASCII "45" == "-".  If "45" were used 
+"     in iskeyword the hyphen would not be picked up.  
+"     This introduces a new option, since the character ranges
+"     specified could be multibyte:
+"         let g:omni_syntax_use_single_byte = 1
+"     This by default will only allow single byte ASCII 
+"     characters to be added and an additional check to ensure
+"     the charater is printable (see documentation for isprint).
+"
+" Version 9.0
+"     Add the check for cpo.
+"
 " Version 8.0
 "     Updated SyntaxCSyntaxGroupItems()
