-  some interfaces were changed slightly to support 
  -stdin -stdout mode.
-  FilterCoder for simple filters
-  Wildcard censor class was changed.
-  Bug was fixed: when encrypted stream was multiple 16,
  it used additional 16 empty bytes.


3.11           2003-10-06
-------------------------
  File functions support unicode strings even
  on Windows 95/98/ME.


3.08.02        2003-09-20
-------------------------
  More compatible with GCC.


3.08.02 beta   2003-08-20
