 Version 0.9.7
-
  - Don't let most characters below 0x0020 through. Old RTF's seem
    to have these for strange reasons.
  - Send data in chunks so massive amounts of picture data don't
    slow down the conversion.
+ - Don't let page number fields through.
 
 Version 0.9.6
  - Add character styles
