 Summary of important user-visible changes for version 3.3:
 ---------------------------------------------------------
 
+ ** The fltk graphics backend now implements the following callback
+    properties: keypressfcn, keyreleasefcn, windowbuttondownfcn,
+    windowbuttonmotionfcn, windowbuttonupfcn, and currentpoint. These
+    enable keyboard and mouse interaction, an example of which can be
+    seen in the __fltk_ginput__.m script.
+
  ** BLAS and LAPACK libraries are now required to build Octave.  The
     subset of the reference BLAS and LAPACK libraries has been removed
     from the Octave sources.
