well, I don't mind much about the standard version numbering ;) But you 
wrote in an earlier mail that some frontends may already support the 1 
bit RGB mode. Since we should at least change the output of the test 
backend to conform with the addition to/clarification of the standard, 
the frontends should have some way to detect this change. So we should 
perhaps add something like

   "Before Sane release 1.0.9 RGB 1 bit data was stored in the reverse
   order."
