     compilation now inline the INVOKE-WITH-SAVED-FP-AND-PC dance.
   * optimization: ROOM no longer conses so egregiously on non-x86oid
     systems.
+  * optimization: associative bitwise operations reassociate patterns like
+    (f (f x k1) k2) to expose (f x (f k1 k2)).  Same for + and * of
+    rational values.
+  * optimization: quasiquote expressions now perform more constant folding,
+    instead of consing equal lists at runtime. (lp#1026439)
 
 changes in sbcl-1.1.7 relative to sbcl-1.1.6:
   * enhancement: TRACE :PRINT-ALL handles multiple-valued forms.
