 changes in sbcl-1.0.16 relative to 1.0.15:
   * minor incompatible change: change PROBE-FILE back to returning
     NIL whenever we can't get a truename, as was the case before 1.0.14.
+  * optimization: MEMBER and ASSOC are over 50% faster for :TEST #'EQ
+    and cases where no :TEST is given but the compiler can infer that
+    the element to search is of type (OR FIXNUM (NOT NUMBER)).
   * bug fix: periodic polling was broken. (thanks to Espen S Johnsen)
   * bug fix: copying output from RUN-PROGRAM to a stream signalled
     bogus errors if select() was interrupted.
