     version 0.7.5, has been removed.  Please use the equivalent
     --disable-debugger option instead.
+  * optimization: REPLACE on declared (UNSIGNED-BYTE 8) vectors, as well
+    as other specialized array types, is much faster.  SUBSEQ and
+    COPY-SEQ on such arrays have also been sped up.
   * fixed inference of the upper bound of an iteration variable.
     (reported by Rajat Datta).
   * fixed bug 376: CONJUGATE type deriver.
