0.8.7.31:

    ** DIRECTORY on logical pathnames is more correct.

    ** CLEAR-INPUT, CLEAR-OUTPUT, FINISH-OUTPUT and FORCE-OUTPUT

       signal a TYPE-ERROR if their argument is not a stream.

    ** READ-BYTE and WRITE-BYTE signal a TYPE-ERROR if their stream

       designator argument does not designate a stream.

planned incompatible changes in 0.8.x:

  * (not done yet, but planned:) When the profiling interface settles

   "Used by READ-BYTE; returns either an integer, or the symbol :EOF

  if the stream is at end-of-file."))
