 changes relative to sbcl-1.1.14:
+  * new feature: the iterative spilling/coloring register allocator developed
+    by Alexandra Barchunova during Google Summer of Code 2013 is now merged
+    in.  By default, it only activates for functions that optimize with
+    (speed 3) and (> speed compilation-speed), but setting
+    sb-regalloc:*register-allocation-method* to :iterative forces its
+    execution.  The previous behaviour can be obtained by instead setting that
+    variable to :greedy.  Thanks again to Google for their support, and, more
+    crucially, to Alexandra Barchunova for her hard work.
   * enhancement: sb-ext:save-lisp-and-die on Windows now accepts
     :application-type argument, which can be :console or :gui. :gui allows
     having GUI applications without an automatically appearing console window.
