+changes relative to sbcl-1.0.57:
+  * enhancement: implicit generic function warnings now specify the package
+    in which the new generic function is being created.
+  * enhancement: SB-EXT:ATOMIC-UPDATE makes it easy to perform non-destructive
+    updates of CAS-able places (similar to Clojure's swap!).
+  * enhancement: run-program no longer decodes and re-encodes environment when
+    :environment argument is not provided. (lp#985904)
+  * bug fix: potential for infinite recursion during compilation of CLOS slot
+    typechecks when dependency graph had loops. (lp#1001799)
+  * bug fix: error forms reported with some program-errors were not escaped
+    properly.
+  * bug fix: functions from EVAL are now on more equal footing with functions
+    from COMPILE. (lp#1000783, lp#851170, lp#922408)
+  * bug fix: ENSURE-GENERIC-METHOD-COMBINATION accepts method combination
+    objects as its :METHOD-COMBINATION argument, not just lists designating
+    method combinations. (lp#936513)
+  * bug fix: run-program no longer unconditionally uses /tmp/ for temporary
+    files. (lp#968837).
+  * optimization: On x86-64, code alignment of block headers is done with
+    multi-byte NOPs now instead of repetitions of the single-byte NOP.
