+changes in sbcl-0.9.11 relative to sbcl-0.9.10:
+  * new feature: Unicode character names are now known to the system
+    (through CHAR-NAME and NAME-CHAR).
+  * bug fix: as implied by AMOP, standardized classes no longer have
+    slots named by external symbols of public packages.  (reported by
+    Pascal Costanza)
+  * optimization: calling functions via constant symbols -- as in 
+    (FUNCALL 'FOO) -- is now roughly as efficient as calling them
+    via the function object as in (FUNCALL #'FOO).
+  * enhancement: CONSTANTP is now able to determine constantness of
+    more complex forms, including calls to constant-foldable standardized
+    functions and some special forms beyond QUOTE.
